I'm looking for a way to convert army time (such as 23:00) to regular time with the AM/PM expression.

回答1:

Just pass your time in strtotime function like this:

$time_in_12_hour_format = date("g:i a", strtotime("23:00"));
echo $time_in_12_hour_format;

http://www.php.net/manual/en/function.date.php

$army_time_str = "23:00";
$regular_time_str = date( 'g:i A', strtotime( $army_time_str ) );
echo $regular_time_str;

input $time is in the form of 'XXXX' (e.g. '0000', '0001',...,'2300'). i couldn't find a function for this so wrote the following. wanted to post here in case anyone else is looking for the same thing.

function convert_army_to_regular($time) {
    $hours = substr($time, 0, 2);
    $minutes = substr($time, 2, 2);

    if ($hours > 12) { 
        $hours = $hours - 12;
        $ampm = 'PM';
    } else {
        if ($hours != 11) {
            $hours = substr($hours, 1, 1);
        }
        $ampm = 'AM';
    }
    return $hours . ':' . $minutes . $ampm;
}
