|
|
<h2>Compatibility</h2>
|
|
|
|
<p>
|
|
PHP 4.2.1 also has improved (but still experimental) support for Apache version 2.
|
|
We do <strong>not</strong> recommend that you use this in a production environment,
|
|
but feel free to test it and report bugs to the <a href="http://bugs.php.net">bug
|
|
system</a>.
|
|
</p>
|
|
|
|
<h2>External variables</h2>
|
|
|
|
<p>
|
|
We would also like to attend you on a big change in PHP 4.2.0 concerning
|
|
variable handling. <strong>External variables (from the environment, the HTTP
|
|
request, cookies or the web server) are no longer registered in the global
|
|
scope by default.</strong> The preferred method of accessing these external
|
|
variables is by using the new Superglobal arrays, introduced in PHP 4.1.0.
|
