It performs an Apache sub-request. It is useful for including CGI scripts or .shtml files, or anything else that you would parse through Apache.

At the minimum that means it must generate a Content-type header. </p> <p class="para"> To run the sub-request, all buffers are terminated and flushed to the browser, pending headers are sent too. </p> <p class="simpara">This function is only supported when PHP is installed as an Apache module.</p> </div> <div class="refsect1 parameters"> <h3 class="title">Parameters</h3> <p class="para"> <dl> <dt> <span class="term"><i><tt class="parameter">filename</tt></i></span> <dd> <p class="para"> The file that the virtual command will be performed on. </p> </dd> </dt> </dl> </p> </div> <div class="refsect1 returnvalues"> <h3 class="title">Return Values</h3> <p class="para"> Performs the virtual command on success, or returns <b><tt>FALSE</tt></b> on failure. </p> </div> <div class="refsect1 changelog"> <h3 class="title">ChangeLog</h3> <p class="para"> <table class="informaltable"> <colgroup> <thead valign="middle"> <tr valign="middle"> <th colspan="1">Version</th> <th colspan="1">Description</th> </tr> </thead> <tbody valign="middle" class="tbody"> <tr valign="middle"> <td colspan="1" rowspan="1" align="left">4.0.6</td> <td colspan="1" rowspan="1" align="left"> This function may be used on PHP files.
