<h2>External variables</h2>
|
|
|
|
<p>
|
|
The biggest change in PHP 4.2.0 concerns 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. More information about this change:</p>

|
<h2>Compatibility</h2>
|
|
|
|
<p>
|
|
The Apache Software Foundation recently released their first
|
|
General Availability version of Apache 2. PHP 4.2.0 will have
|
|
<strong>EXPERIMENTAL</strong> support for this version. You can
|
|
build a DSO module for Apache 2 with --with-apxs2. We do
|
|
<strong>not</strong> recommend that you use this in a production
|
|
environment.
|
|
</p>
|
|
<p>
|
|
PHP 4.2.0 still lacks certain key features on Mac OS X and
|
|
Darwin, and isn't officially supported by the PHP Group on
|
|
these platforms. Specifically, building PHP as a dynamically
|
|
loaded Apache module isn't supported at this time. PHP 4.3.0,
|
|
due to be released in August, 2002, will be the first PHP
|
|
release to officially support Mac OS X. It, along with future
|
|
Mac OS X and Apache releases, will enable full feature parity
|
|
with other PHP platforms. <strong>Update:</strong>

overcoming these limitations</a>
