我怎么知道fastcgi_finish_request（）是否可用？ [重复]
问题描述：
This question already has an answer here:
Is there any approach like:
if (extension_loaded('apc') && ini_get('apc.enabled'))
{
echo "APC enabled!";
}
Cheers

答
You can test with function_exists():
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";
}
