PHP date time to date, time split function with period

split-date-time.php

<?php

// made this way so it only has to be called once
// did a dumb thing using a date/time storage with separate date time fields in MySQL with hourly period in the time part
// harder to sort natively with MySQL

function split_date_time($cur_date_time) {
    // split date_time components
    $date_time_split = explode(' ', $cur_date_time);
    // return array
    $date_time_arr = [];
    $date_time_arr['date'] = $date_time_split[0];
    // deal with period
    $cur_hour = explode(':', $date_time_split[1]);
    if (intval($cur_hour[0]) > 12) {
        // pm case
        $date_time_arr['time'] = $cur_hour[0]%12 . ':' . $cur_hour[1] . ' PM';
    }
    else {
        $date_time_arr['time'] = $cur_hour[0] . ':' . $cur_hour[1] . ' AM';
    }
    return $date_time_arr;
}

// example use
echo split_date_time(2017-08-15 13:10:00)['date']; // outputs date component
echo split_date_time(2017-08-15 13:10:00)['time']; // outputs time component
