Convert Time String to Decimal Hours PHP

Question

I would like to convert time strings (Such as 2:12:0) to decimal format in hours (ex 2:12:0 would be 2.2 hours) in PHP.

Solution

A fairly dumb conversion from the top of my head, using explode by colon:

<?php 

$hms = "2:12:0";
$decimalHours = decimalHours($hms);

function decimalHours($time)
{
    $hms = explode(":", $time);
    return ($hms[0] + ($hms[1]/60) + ($hms[2]/3600));
}

echo $decimalHours;

?>

Had an error in the return line (in the seconds part). It's $hms[2]/3600 and not $hms[1]/3600. Sorry.
