Using old code with new versions of PHP

Now that PHP has grown to be a popular scripting language, there are a lot of public repositories and libraries containing code you can reuse. The PHP developers have largely tried to preserve backwards compatibility, so a script written for an older version will run (ideally) without changes in a newer version of PHP. In practice, some changes will usually be needed.

Two of the most important recent changes that affect old code are:

• The deprecation of the old $HTTP_*_VARS arrays (which need to be indicated as global when used inside a function or method). The following superglobal arrays were introduced in PHP » 4.1.0. They are: $_GET,$_POST, $_COOKIE, $_SERVER, $_FILES, $_ENV, $_REQUEST, and $_SESSION. The older$HTTP_*_VARS arrays, such as $HTTP_POST_VARS, also exist. As of PHP 5.0.0, the long PHP predefined variable arrays may be disabled with the register_long_arrays directive.


• External variables are no longer registered in the global scope by default. In other words, as of PHP» 4.2.0 the PHP directive register_globals is off by default in php.ini. The preferred method of accessing these values is via the superglobal arrays mentioned above. Older scripts, books, and tutorials may rely on this directive being on. If it were on, for example, one could use $id from the URLhttp://www.example.com/foo.php?id=42. Whether on or off, $_GET['id'] is available.

Dealing with Forms

One of the most powerful features of PHP is the way it handles HTML forms. The basic concept that is important to understand is that any form element will automatically be available to your PHP scripts. Please read the manual section on Variables from external sources for more information and examples on using forms with PHP. Here is an example HTML form:

Example #1 A simple HTML form

<form action="action.php" method="post">

 <p>Your name: <input type="text" name="name" /></p>

 <p>Your age: <input type="text" name="age" /></p>

 <p><input type="submit" /></p>

</form>

There is nothing special about this form. It is a straight HTML form with no special tags of any kind. When the user fills in this form and hits the submit button, the action.php page is called. In this file you would write something like this:

Example #2 Printing data from our form

Hi <?php echo htmlspecialchars($_POST['name']); ?>.
You are <?php echo (int)$_POST['age']; ?> years old.

A sample output of this script may be:

Hi Joe. You are 22 years old.

Apart from the htmlspecialchars() and (int) parts, it should be obvious what this does. htmlspecialchars()makes sure any characters that are special in html are properly encoded so people can't inject HTML tags or Javascript into your page. For the age field, since we know it is a number, we can just convert it to an integerwhich will automatically get rid of any stray characters. You can also have PHP do this for you automatically by using the filter extension. The $_POST['name'] and $_POST['age'] variables are automatically set for you by PHP. Earlier we used the $_SERVER superglobal; above we just introduced the $_POST superglobal which contains all POST data. Notice how the method of our form is POST. If we used the method GET then our form information would live in the $_GET superglobal instead. You may also use the $_REQUEST superglobal, if you do not care about the source of your request data. It contains the merged information of GET, POST and COOKIE data. Also see the import_request_variables() function.

You can also deal with XForms input in PHP, although you will find yourself comfortable with the well supported HTML forms for quite some time. While working with XForms is not for beginners, you might be interested in them. We also have a short introduction to handling data received from XForms in our features section.

Something Useful

Let us do something more useful now. We are going to check what sort of browser the visitor is using. For that, we check the user agent string the browser sends as part of the HTTP request. This information is stored in a variable. Variables always start with a dollar-sign in PHP. The variable we are interested in right now is$_SERVER['HTTP_USER_AGENT'].

Note:

$_SERVER is a special reserved PHP variable that contains all web server information. It is known as a superglobal. See the related manual page on superglobals for more information. These special variables were introduced in PHP » 4.1.0. Before this time, we used the older $HTTP_*_VARS arrays instead, such as$HTTP_SERVER_VARS. Although deprecated, these older variables still exist. (See also the note on old code.)

To display this variable, you can simply do:

Example #1 Printing a variable (Array element)

<?phpecho $_SERVER['HTTP_USER_AGENT'];?>

A sample output of this script may be:

Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)

There are many types of variables available in PHP. In the above example we printed an Array element. Arrays can be very useful.

$_SERVER is just one variable that PHP automatically makes available to you. A list can be seen in the Reserved Variables section of the manual or you can get a complete list of them by looking at the output of the phpinfo()function used in the example in the previous section.

You can put multiple PHP statements inside a PHP tag and create little blocks of code that do more than just a single echo. For example, if you want to check for Internet Explorer you can do this:

Example #2 Example using control structures and functions

<?phpif (strpos($_SERVER['HTTP_USER_AGENT'], 'MSIE') !== FALSE) {
    echo 'You are using Internet Explorer.<br />';
}?>

A sample output of this script may be:

You are using Internet Explorer.<br />

Here we introduce a couple of new concepts. We have an if statement. If you are familiar with the basic syntax used by the C language, this should look logical to you. Otherwise, you should probably pick up an introductory PHP book and read the first couple of chapters, or read the Language Reference part of the manual.

The second concept we introduced was the strpos() function call. strpos() is a function built into PHP which searches a string for another string. In this case we are looking for 'MSIE' (so-called needle) inside$_SERVER['HTTP_USER_AGENT'] (so-called haystack). If the needle is found inside the haystack, the function returns the position of the needle relative to the start of the haystack. Otherwise, it returns FALSE. If it does not return FALSE, the if expression evaluates to TRUE and the code within its {braces} is executed. Otherwise, the code is not run. Feel free to create similar examples, with if, else, and other functions such as strtoupper()and strlen(). Each related manual page contains examples too. If you are unsure how to use functions, you will want to read both the manual page on how to read a function definition and the section about PHP functions.

We can take this a step further and show how you can jump in and out of PHP mode even in the middle of a PHP block:

Example #3 Mixing both HTML and PHP modes

<?phpif (strpos($_SERVER['HTTP_USER_AGENT'], 'MSIE') !== FALSE) {?><h3>strpos() must have returned non-false</h3>
<p>You are using Internet Explorer</p>
<?php} else {?><h3>strpos() must have returned false</h3>
<p>You are not using Internet Explorer</p>
<?php}?>

A sample output of this script may be:

<h3>strpos() must have returned non-false</h3>

<p>You are using Internet Explorer</p>

Instead of using a PHP echo statement to output something, we jumped out of PHP mode and just sent straight HTML. The important and powerful point to note here is that the logical flow of the script remains intact. Only one of the HTML blocks will end up getting sent to the viewer depending on the result of strpos(). In other words, it depends on whether the string MSIE was found or not.

Your first PHP-enabled page

Create a file named hello.php and put it in your web server's root directory (DOCUMENT_ROOT) with the following content:

Example #1 Our first PHP script: hello.php

<html>
 <head>
  <title>PHP Test</title>
 </head>
 <body>
 <?php echo '<p>Hello World</p>'; ?>
 </body>
</html>

Use your browser to access the file with your web server's URL, ending with the /hello.php file reference. When developing locally this URL will be something like http://localhost/hello.php orhttp://127.0.0.1/hello.php but this depends on the web server's configuration. If everything is configured correctly, this file will be parsed by PHP and the following output will be sent to your browser:

<html>

 <head>

  <title>PHP Test</title>

 </head>

 <body>

 <p>Hello World</p>

 </body>

</html>

This program is extremely simple and you really did not need to use PHP to create a page like this. All it does is display: Hello World using the PHP echo() statement. Note that the file does not need to be executable or special in any way. The server finds out that this file needs to be interpreted by PHP because you used the ".php" extension, which the server is configured to pass on to PHP. Think of this as a normal HTML file which happens to have a set of special tags available to you that do a lot of interesting things.

If you tried this example and it did not output anything, it prompted for download, or you see the whole file as text, chances are that the server you are on does not have PHP enabled, or is not configured properly. Ask your administrator to enable it for you using the Installation chapter of the manual. If you are developing locally, also read the installation chapter to make sure everything is configured properly. Make sure that you access the file via http with the server providing you the output. If you just call up the file from your file system, then it will not be parsed by PHP. If the problems persist anyway, do not hesitate to use one of the many » PHP support options.

The point of the example is to show the special PHP tag format. In this example we used <?php to indicate the start of a PHP tag. Then we put the PHP statement and left PHP mode by adding the closing tag, ?>. You may jump in and out of PHP mode in an HTML file like this anywhere you want. For more details, read the manual section on the basic PHP syntax.

Note: A Note on Line Feeds

Line feeds have little meaning in HTML, however it is still a good idea to make your HTML look nice and clean by putting line feeds in. A linefeed that follows immediately after a closing ?> will be removed by PHP. This can be extremely useful when you are putting in many blocks of PHP or include files containing PHP that aren't supposed to output anything. At the same time it can be a bit confusing. You can put a space after the closing ?> to force a space and a line feed to be output, or you can put an explicit line feed in the last echo/print from within your PHP block.

Note: A Note on Text Editors

There are many text editors and Integrated Development Environments (IDEs) that you can use to create, edit and manage PHP files. A partial list of these tools is maintained at » PHP Editors List. If you wish to recommend an editor, please visit the above page and ask the page maintainer to add the editor to the list. Having an editor with syntax highlighting can be helpful.

Note: A Note on Word Processors

Word processors such as StarOffice Writer, Microsoft Word and Abiword are not optimal for editing PHP files. If you wish to use one for this test script, you must ensure that you save the file as plain text or PHP will not be able to read and execute the script.

Note: A Note on Windows Notepad

If you are writing your PHP scripts using Windows Notepad, you will need to ensure that your files are saved with the .php extension. (Notepad adds a .txt extension to files automatically unless you take one of the following steps to prevent it.) When you save the file and are prompted to provide a name for the file, place the filename in quotes (i.e. "hello.php"). Alternatively, you can click on the 'Text Documents' drop-down menu in the 'Save' dialog box and change the setting to "All Files". You can then enter your filename without quotes.

Now that you have successfully created a working PHP script, it is time to create the most famous PHP script! Make a call to the phpinfo() function and you will see a lot of useful information about your system and setup such as available predefined variables, loaded PHP modules, and configuration settings. Take some time and review this important information.

Example #2 Get system information from PHP

<?php phpinfo(); ?>

How to Create My Own PHP Website

What do I need?

In this tutorial we assume that your server has activated support for PHP and that all files ending in .php are handled by PHP. On most servers, this is the default extension for PHP files, but ask your server administrator to be sure. If your server supports PHP, then you do not need to do anything. Just create your .php files, put them in your web directory and the server will automatically parse them for you. There is no need to compile anything nor do you need to install any extra tools. Think of these PHP-enabled files as simple HTML files with a whole new family of magical tags that let you do all sorts of things. Most web hosts offer PHP support, but if your host does not, consider reading the »  PHP Links section for resources on finding PHP enabled web hosts.

Let us say you want to save precious bandwidth and develop locally. In this case, you will want to install a web server, such as » Apache, and of course » PHP. You will most likely want to install a database as well, such as» MySQL.

You can either install these individually or choose a simpler way. Our manual has installation instructions for PHP(assuming you already have some web server set up). If you have problems with installing PHP yourself, we would suggest you ask your questions on our » installation mailing list. If you choose to go on the simpler route, then » locate a pre-configured package for your operating system, which automatically installs all of these with just a few mouse clicks. It is easy to setup a web server with PHP support on any operating system, including MacOSX, Linux and Windows. On Linux, you may find » rpm find and » PBone helpful for locating RPMs. You may also want to visit » apt-get to find packages for Debian.

How to get to a MS-DOS prompt or Windows command line.

Windows Vista and 7 users

1. Click Start.
2. Type cmd and press enter.

If you're attempting to get into a MS-DOS prompt to troubleshoot the computer boot the computer into Safe Mode.

Windows NT, 2000, and XP users

1. Click Start.
2. Click Run.
3. Type cmd or command and press enter.

• Difference between the command.com and cmd.exe.

If you're attempting to get into a MS-DOS prompt to troubleshoot the computer, boot the computer into Safe Mode.

Windows 2000 and XP users who are unable to boot the computer into Normal Windows mode or Safe mode, can also enter the recovery console to manage their computer from a prompt. Additional information about how to do this can be found on document CH000627.

Finally, if you are experiencing issues getting into Windows NT, 2000, or XP, it may be necessary to run troubleshooting steps from a MS-DOS prompt. It is recommended that the Network Administrator get into the MS-DOS prompt by using either a standard MS-DOS boot diskette (note: will not be able to access data using a standard MS-DOS bootable diskette) or the ERD diskettes created after the installation of Windows NT, or boot from the Windows XP CD.

Windows 95, 98, and ME users

If you are able to get into Windows 95, 98 or ME, you can get to a MS-DOS prompt by following the steps below.

1. Click Start
2. Click Run
3. Type "command" and press enter.

This will open a MS-DOS shell. However, if you are attempting to troubleshoot an issue with the computer and are using Microsoft Windows 95 or Windows 98, we suggest you restart the computer into MS-DOS. To do this follow the below steps.

1. Click Start
2. Click Shutdown
3. Choose the option to restart the computer into a MS-DOS prompt.

If you are unable to get into Windows 95 or Windows 98 to get into a MS-DOS prompt, follow the below instructions (Windows ME does not have this option).

1. Reboot the computer
2. As the computer is booting, press the F8 key when you hear a beep or when you see "Starting Windows 95" or "Starting Windows 98." Windows 98 users sometimes may find it easier to press and hold the left CTRL key as the computer is booting.
3. If done properly the user should get to a screen similar to the below screen.

Microsoft Windows 95 Startup Menu ============================= 1. Normal 2. Logged (\BOOTLOG.TXT) 3. Safe mode 4. Step-by-step confirmation 5. Command prompt only 6. Safe mode command prompt only Enter a choice: 1 F5=Safe Mode Shift+F5=Command prompt Shift+F8= Step-by-step confirmation [N]

   4.   Select the option for Safe mode command prompt only.

MS-DOS users

If you are running MS-DOS with no other operating systems, the computer should be booting into a MS-DOS prompt automatically unless you have a shell or other program loading automatically.

If the computer is not getting you to a MS-DOS prompt, reboot the computer and as the computer is booting, press the F5 key when you see the message "Starting MS-DOS" or the MS-DOS version. This will load the default standard MS-DOS.

If you successfully get to a MS-DOS prompt and would like to prevent the computer from loading the program that is preventing you from getting to a MS-DOS prompt, or if you would like to fix possible error messages you may be receiving when booting the computer, edit the autoexec.bat or the config.sys files.

Windows 3.x users

If you are running Windows 3.x it is likely that the computer is booting into Windows automatically and bypassing the MS-DOS prompt. If Windows loads successfully into Windows, to exit to a MS-DOS prompt, from Program Manager, click the File menu and then Exit.

If the computer is trying to load into Windows but is encountering errors while it is booting, reboot the computer and press F5 key when you see the message "Starting MS-DOS" or the MS-DOS version. This will load the default standard MS-DOS.

If you do not want Windows 3.x to load automatically into Windows 3.x, you will need to edit the autoexec.batfile and remove the "win" line.

Other operating system users

If you are using another operating system such as OS/2, Linux variants, or Unix variants and you need to get to a MS-DOS prompt, it is recommended that you use a MS-DOS boot diskette unless you are dual booting the computer. Keep in mind that booting from a MS-DOS diskette is not going to allow you to have access to the files used with other operating systems. However, if you're erasing everything and starting over this would allow you to delete all pre-existing information and start over.
