How do I know if fastcgi_finish_request() is available?

Question

Is there any approach like:

if (extension_loaded('apc') && ini_get('apc.enabled'))
{
echo "APC enabled!";
}

Cheers

Answer 1

You can test with function_exists():

• function_exists — Return TRUE if the given function has been defined

Checks the list of defined functions, both built-in (internal) and user-defined, for function_name […] Returns TRUE if function_name exists and is a function, FALSE otherwise.

Example usage:

if (function_exists('fastcgi_finish_request')) {
    fastcgi_finish_request();
}

fastcgi_finish_request() is not a module but a function, to check if you can call it you would do :

if (function_exists('fastcgi_finish_request')) {
  echo "fastcgi enabled";
}
