在PHP中将mm：ss转换为毫秒

Question

请告诉我如何在PHP中将mm：ss转换为毫秒。

$value = "10:10"

$ms = ...

Answer 1

无需进行字符串转换或数组操作：

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

Answer 4

$value = "10:10";

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

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

var_dump($milliseconds); // 610000
