<h1>Documentation for PHP 4</h1>
|
|
|
|
<h2>Introduction</h2>
|
|
<p>
|
|
The PHP 4 documentation was removed from the PHP Manual in August 2014,
|
|
approximately six years after PHP 4 reached its end of life. However, we have
|
|
provided downloadable copies of the manual for anyone who would need it, as well
|
|
as a link to a hosted third-party version.
|
|
</p>
|
|
|
|
<h2>PHP 4 Manual</h2>
|
|
<p>
|
|
An attempt has been made to preserve as much documentation related to PHP 4 as
|
|
possible. Despite this, we don't have a nice, separate manual covering only PHP 4.
|
|
The reason for this is how our documentation is structured. Even so, the linked copies
|
|
describe more aspects of PHP 4 than the actual manual described in August 2014 (e.g.
|
|
it covers more PHP 4 extensions).
|
|
</p>
|
|
|
|
<ul>

|
|
You can download a copy in the <a href="http://doc.php.net/archives/">documentation archives</a>.
|
|
</li>
|
|
<li>
|
|
You can also find the <a href="https://php-legacy-docs.zend.com/manual/php4/en/index">PHP 4 legacy manual</a>
|
|
on the Zend site, which was created from the official archives. This version of the manual is
|
|
maintained by Zend and not the PHP Documentation Group. Any questions about its content should be reported
|
|
via the "Report a Bug" links on the appropriate pages.
|

</ul>

|
|
|
<p>
|
|
Please remember that these documentation versions <strong>should not
|
|
</strong> be used in everyday development, unless you are maintaining PHP 4 applications.
|
|
These versions lacks many topics connected with newer PHP versions and are not updated anymore.
|
|
</p>

|
<h2>Migrating to supported PHP version</h2>
|
|
<p>
|
|
All users are strongly encouraged to upgrade their environments to newest PHP version.
|
|
Please read our guides for <a href="http://php.net/manual/en/migration5.php">Migrating
|
|
from PHP 4 to PHP 5.0.x</a> for more information.
