Return a file extention from a string

This php function returns a file extention from a string. 

I think it will only work if the string does not have any additional . in it. 

I think a better way to do this function would be to split the string into an array on the . and then select the last dot content. 

Actually after testing this it does already locate the last . location. Test Link with multiple .'s

// return a file extention
	function get_file_extension($file_name) {
		return substr(strrchr($file_name,'.'),1);

echo get_file_extension($file_name = "1.2.3456.678-asz.txt");

For a long time it had seemed to me that life was about to begin - real life. But there was always some obstacle in the way, something to be gotten through first, some unfinished business, time still to be served, or a debt to be paid. Then life would begin. At last it dawned on me that these obstacles were my life.
