从表单提交时间时从$ _post中删除AM / PM

Question

I have a form on my website which allows a user to select a time.

when the user posts the time - it is currently posting as 12:00 PM

What is the best way to remove the PM or the AM from $eventtime and replace it with :00

I am using a timepicker jquery plugin, which automatically adds the AM / PM.

And my PHP converts the selected date and time into a timestamp.

My html element

<input type="text" id="booking-time1" name ="selectedtime" value="" />

PHP

$eventdate = $this->input->post('selecteddate');
$eventtime = $this->input->post('selectedtime');


$timestamp = strtotime(''.$eventdate.' '.$eventtime.'');

Answer 1

I would use preg_replace.

$time = "12:00 PM";
$newTime = preg_replace('/ ?[AP]M$/', ':00', $time);
echo $newTime;

But as stated in the comments you are losing some information by doing that. You could also extract the AM/PM using a similar regular expression and preg_match

preg_match('/[AP]M$/', $time, $match);
var_dump($match);
