How to sort an array of times chronologically?

Question

I have a non-associative array where the data that comes in is not sorted (I\'m receiving the data from an outside system and cannot force it to come into the array in sorte

Answer 1

sort, like all of php's sorting functions, sorts in-place. It returns true if the sorting was successful, false otherwise. This result is irrelevant if you're only sorting strings/numbers.

$wedTrackTimes = array("9:30 AM-10:30 AM", "8:15 AM-9:15 AM",
                       "12:30 PM-1:30 PM", "2:00 PM-3:00 PM", "3:30 PM-4:30 PM");
$wedTrackTimes = array_unique($wedTrackTimes);
sort($wedTrackTimes);
print_r($wedTrackTimes);

is the way to go.
