How can I make an array of times with half hour intervals?

Question

I needed a list of times like so in an array...

12am
12:30am
1:00pm
...

How can I do this with PHP?

Answer 1

We can simply use strtotime to increment our time by N amount here in this case 30 minutes and date function to format it to our desired output.

$startTime = strtotime('12 am');
$endTime   = strtotime('11:59 pm');

$arrInterval = [];
while($endTime >= $startTime){
  $arrInterval[] = date("h:ia", $startTime);
  $startTime = strtotime('+30 minutes', $startTime);
}
