How to speed up the processing of dates

[tahishae]

function pc_date_sort() the example shows how to sort the dates.

function pc_date_sort($a, $b) {
    list($a_month, $a_day, $a_year) = explode('/', $a);
    list($b_month, $b_day, $b_year) = explode('/', $b);
    if ($a_year > $b_year ) return 1;
    if ($a_year < $b_year ) return -1;
    if ($a_month > $b_month) return 1;
    if ($a_month < $b_month) return -1;
    if ($a_day > $b_day ) return 1;
    if ($a_day < $b_day ) return -1;
    return 0;
}
$dates = array('12/14/2000', '08/07/1999', '08/10/2001');
usort($dates, 'pc_date_sort');
echo '<pre>';
print_r($dates);

Weort(s) is often the function of usort whenever it is I need to compare the two elements recalculate the values, return. The sorting function, which slows the process.

Please help me streamline the code. How to avoid unnecessary work?

use standard built-in http://php.net/manual/en/class.datetime.php ♪ It used to be a bicycle town with dates.

• a built-in datetime written on C, it will be faster,
• He's challenged and safer.
• He offers more opportunities than his bike.

You can add it to your class/function, inheriting it.
