Prior to PHP 4.3.3, <span class="function"><a href="getallheaders.html" class="function">getallheaders()</a></span> was only
|
|
available for the Apache servers. After PHP 4.3.3,

|
<span class="function"><a href="getallheaders.html" class="function">getallheaders()</a></span> is an alias for
|
|
<span class="function"><strong>nsapi_request_headers()</strong></span> if you use the NSAPI module.

You can also get at the value of the common CGI variables by

reading them from the <var class="varname"><var class="varname"><a href="reserved.variables.server.html" class="classname">$_SERVER</a></var></var> superglobal, which
