VIRTUAL(3) 1 VIRTUAL(3)virtual - Perform an Apache sub-requestSYNOPSIS
bool virtual (string $filename)
DESCRIPTION virtual(3) is an Apache-specific function which is similar to <!--#include virtual...--> in mod_include. 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. Note that for a CGI script,
the script must generate valid CGI headers. At the minimum that means it must generate a Content-Type header.
To run the sub-request, all buffers are terminated and flushed to the browser, pending headers are sent too.
This function is supported when PHP is installed as an Apache module or by the NSAPI server module in Netscape/iPlanet/SunONE webservers.
PARAMETERS
o $filename
- The file that the virtual command will be performed on.
RETURN VALUES
Performs the virtual command on success, or returns FALSE on failure.
EXAMPLES
See apache_note(3) for an example.
NOTES
Warning
The query string can be passed to the included file but $_GET is copied from the parent script and only $_SERVER['QUERY_STRING'] is
filled with the passed query string. The query string may only be passed when using Apache 2. The requested file will not be listed
in the Apache access log.
Note
Environment variables set in the requested file are not visible to the calling script.
Note
This function may be used on PHP files. However, it is typically better to use include(3) or require(3) for PHP files.

NSAPI_REQUEST_HEADERS(3) 1 NSAPI_REQUEST_HEADERS(3)nsapi_request_headers - Fetch all HTTP request headersSYNOPSIS
array nsapi_request_headers (void )
DESCRIPTION nsapi_request_headers(3) gets all the HTTP headers in the current request. This is only supported when PHP runs as a NSAPI module.
Note
Prior to PHP 4.3.3, getallheaders(3) was only available for the Apache servers. After PHP 4.3.3, getallheaders(3) is an alias for
nsapi_request_headers(3) if you use the NSAPI module.
Note
You can also get at the value of the common CGI variables by reading them from the $_SERVER superglobal, which works whether or not
you are using PHP as a NSAPI module.
RETURN VALUES
Returns an associative array with all the HTTP headers.
EXAMPLES
Example #1
nsapi_request_headers(3) example
<?php
$headers = nsapi_request_headers();
foreach ($headers as $header => $value) {
echo "$header: $value <br />
";
