PHP average time from an array

Question

How do I work out the average time from an array of times.

I have an array that looks like this :

(\'17:29:53\',\'16:00:32\')

And I

Answer 1

$times = array('17:29:53','16:00:32');

$totaltime = '';
foreach($times as $time){
        $timestamp = strtotime($time);
        $totaltime += $timestamp;
}

$average_time = ($totaltime/count($times));

echo date('H:i:s',$average_time);

Answer 2

1. Loop over all Entries and add times, converted to seconds
2. Divide by length of Array and convert back to hh:mm:ss

Answer 3

• convert both using strtotime() function
• add the value
• divide by 2 (or how many items there in your array)
• convert back to normal time format

Answer 4

date('H:i:s', array_sum(array_map('strtotime', $array)) / count($array))

Untested solution typed on my phone, should work though.
