将时间转换为Php中的整数

Question

How would you convert time to integer?

 string(8) "04:04:07"

I want this as 4(hours) or much better 4.04(4hours and 4 minutes)

I tried

  $yourdatetime = "04:04:07";
  $timestamp = strtotime($yourdatetime);

Which results in

 int(1458590887)

Answer 1

Use (float) and preg_replace to one-line-code conversion:

$floatval = (float) preg_replace('/^(\d+):(\d+).+/','\1.\2',$yourdatetime);
