Re: [PHP] Sorting times (SOLVED)
Just a draft i thought should not go unnoticed on the list :-) just cleaning
up.
OK,
How about a super efficient soln where each string is only converted once
and a fast sorting algorithm is used:
?php
function time_sort($a, $b) {
static $now = time();
if (strtotime($a, $now) == strtotime($b, $now)) {
return 0;
}
return (strtotime($a, $now) strtotime($b, $now) ? -1 : 1;
}
function sortTime($times) {
}

I don't see another way. You go through the array converting string to
time (seconds), sort, and then convert back. You have to go through the
array more than once.

The other way, is the most likely ultra-fast solution I posted.

1. convert the string representation of times to timestamps using strtotime()
2. sort the timestamps
3. display the timestamps as strings using date('format', timestamp)
Would that work?

Bingo -- that worked!

Here's the code.
?php
// == returns a time array sorted
function sortTime($in_times)
{
$time = array();
foreach ($in_times as $t)
{
$time [] = strtotime($t);
}
sort($time);
$sort_time = array();
foreach ($time as $t)
{
$sort_time[] = date('g:ia', $t);
}
return $sort_time;
}
?
