In the whole guide, PHP 4.0.6 or later version is assumed, however most of information will also be applicable to earlier versions of PHP. All OS-specific stuff will be marked as such.

PHP allows overloading of property access and method calls by implementing
special proxy methods that are invoked if the relevant property or method
doesn’t exist. This gives you a lot of flexibility in intercepting these actions and defining your own functionality.

Perhaps the most important thing to note about the object-oriented improvements of PHP 5 is that objects are now referenced by handle and not by value.

Appendix A, “PEAR and PECL Package Index,” provides an overview of all important packages, with descriptions and dependencies on other packages. Appendix B, “phpDocument Format Reference,” explains the syntax as understood by the PHP Documenter tool to generate API documentation from source code. Appendix C, “Zend Studio Quick Start,” is an introduction to working in the Zend Studio IDE.

Because a real-life situation will rarely match the book’s example problems precisely, PHP 5 in Practice explains the solution well enough that you will understand it and can learn how to truly solve your own problem.

ErrorDocument 404 /error.php

Can be used to redirect all 404 errors to a PHP script. The following server variables are of interest:

1. $REDIRECT_ERROR_NOTES - File does not exist: /docroot/bogus
2. $REDIRECT_REQUEST_METHOD - GET
3. $REDIRECT_STATUS - 404
4. $REDIRECT_URL - /docroot/bogus

Don’t forget to send a 404 status if you choose not to redirect to a real page.

<? Header('HTTP/1.0 404 Not Found'); ?>

Interesting uses

1. Search for closest matching valid URL and redirect
2. Use attempted url text as a DB keyword lookup
3. Funky caching

An interesting way to handle caching is to have all 404’s redirected to a PHP script.

ErrorDocument 404 /generate.php

Then in your generate.php script use the contents of $REDIRECT_URI to determine which URL the person was trying to get to. In your database you would then have fields linking content to the URL they affect and from that you should be able to generate the page. Then in your generate.php script do something like:

<?php $s = $REDIRECT_URI; $d = $DOCUMENT_ROOT; // determine requested uri $uri =
substr($s, strpos($s,$d) + strlen($d) + 1); ob_start(); //
Start buffering output // ... code to fetch and output content from DB ... $data = ob_get_contents(); $fp =
fopen("$DOCUMENT_ROOT/$uri",'w'); fputs($fp,$data); fclose($fp); ob_end_flush(); // Flush and turn off buffering ?>

So, the way it works, when a request comes in for a page that doesn’t exist, generate.php checks the database and determines if it should actually exist and if so it will create it and respond with this generated data. The next request for that same URL will get the generated page directly. So in order to refresh your cache you simply have to delete the files.
