Question

目前，我有以下时间格式：

0m12.345s
2m34.567s

我把它们放在变量$time中。如何仅在PHP中将变量转换为秒，例如第一个变为12.345，第二个变为154.567？

Answer 1

你可以这样做，

//Exploding time string on 'm' this way we have an array 
//with minutes at the 0 index and seconds at the 1 index
//substr function is used to remove the last s from your initial time string
$time_array=explode('m', substr($time, 0, -1));
//Calculating 
$time=($time_array[0]*60)+$time_array[1];

Answer 2

<?php
    $time="2m34.567s";
    $split=explode('m',$time);
//   print_r($split[0]);
    $split2=explode('s',$split[1]);

$sec= seconds_from_time($split[0])+$split2[0];
echo $sec;
function seconds_from_time($time) {

        return $time*60;
    }

?>
