php calculate time difference in percentage
First, make those minutes into seconds:
4 min 35 sec = 275 seconds
11 min = 660 seconds
Your percentage of remaining time will be (275 / 660) * 100. The percentage of time left would be ((660 - 275) / 660) * 100. Of course, that's all in seconds. Don't know how you are receiving that time in php, but it might look like:
$maxTime = 660;
$timeTaken = 275;
$percentage = ($timeTaken / $maxTime) * 100;
// To get percentage of time left
$percentLeft = (($maxTime - $timeTaken) / $maxTime) * 100;
