Help with php site

A good place to start is by skimming through the ever-growing list of frequently asked questions (with answers, of course). Then have a look at the rest of the online manual and other resources in the documentation section.

Mailing Lists

There are a number of mailing lists devoted to talking about PHP and related projects. This list describes them all, has links to searchable archives for all of the lists, and explains how to subscribe to the lists.

Newsgroups

The PHP language newsgroup is comp.lang.php, available on any news server around the globe. In addition to this many of our mailing lists are also reflected onto the news server at news://news.php.net/. The server also has a read only web interface at http://news.php.net/.

Mailing list messages are transfered to newsgroup posts and newsgroup posts are sent to the mailing lists. Please note that these newsgroups are only available on this server.

User Groups

Chances are that there is a User Group in your neighborhood, which are generally a great resource both for beginners and experienced PHP users. Check out the User Group listing on PHP.ug to see if there is one close by.

Events & Training

Internet Relay Chat

Otherwise known as IRC. Here you can usually find experienced PHP people sitting around doing nothing on various channels with php in their names. Note that there is no official IRC channel. Check Libera.Chat or any other major network (EFNet, QuakeNet, IRCNet, IrCQNet, DALNet and OFTC).

PHP.net webmasters

If you have a problem or suggestion in connection with the PHP.net website or mirror sites, please contact the webmasters. If you have problems setting up PHP or using some functionality, please ask your question on a support channel detailed above, the webmasters will not answer any such questions.

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

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 or http://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:

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 . 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.

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
