Answer 1

You just have to use the strtotime() function, passing it your time :

$ts = strtotime('09:00');
var_dump($ts);

And you'll get :

int 1300435200

Note : if you don't specify the date, strtotime will use today .

You could also use the DateTime class :

$dt = new DateTime('09:00');
$ts = $dt->format('U');
var_dump($ts);

Answer 2

使用strtotime ：

$timestamp = strtotime('09:00');
