How To Check if the cURL PHP extension is loaded

There is not a lot of information about checking if a particular extension is loaded and the few tidbits there are on the internet, are very impractical, so I decided to dig a bit deeper and I came up with my own solution.

The following function returns TRUE if it can find the cURL extension installed, and FALSE if it fails to find it.

// ### Checks for presence of the cURL extension.
function _iscurlinstalled() {
	if  (in_array  ('curl', get_loaded_extensions())) {
		return true;
	}
	else{
		return false;
	}
}

Sample usage:

if (_iscurlinstalled()) echo "cURL is installed"; else echo "cURL is NOT installed";
