將mm：ss轉換爲以毫秒爲單位的PHP

Question

能否讓我知道如何將mm：ss轉換爲以毫秒爲單位的PHP。

$value = "10:10"

$ms = ...

Answer 1

不需要做字符串轉換或數組操作：

sscanf($value, "%d:%d", $minutes, $seconds); 
$ms = $seconds * 1000 + $minutes * 60 * 1000; 

Answer 2

$ms = intval(substr($value, 0, 2))*60*1000 + intval(substr($value, 2, 2))*1000;

Answer 3

$value = "10:10"; 

list($minutes, $seconds) = explode(':', $value); 

$milliseconds = $seconds * 1000 + $minutes * 60000; 

var_dump($milliseconds); // 610000 

Answer 4

$value = "10:10"; 
$time = explode(':',$value); 
$ms = $time[0]*60000 + $time[1]*1000;
