	$minutes = sprintf('%02d',(int) $minutes);
	$seconds = sprintf('%02d',(int) $seconds);
	$meridiem = (strtolower($meridiem)=='am') ? 'am' : 'pm';
	return date('H:i:s', strtotime("{$hours}:{$minutes}:{$seconds} {$meridiem}"));

echo to_24_hour( 1, 2, 3, 'pm' ); // Returns 13:02:03

Initial Description
Convert 12-hour time format with hour, minutes, seconds, and meridiem into 24-hour  format. Performs data correction to make sure hours, minutes and seconds have leading zeros if needed.

The trick here is to use strtotime() where we pass the time string in this format: "hh:mm:ss meridiem" 
Example: "02:30:00 pm"
