将javascript时间函数转换为php

Question

I have an working javascript code that i use on an webpage to set text of an button. The text of the button show the time in 24 hour format with added 1 hour and 30 minutes rounded of to nearest 5 minutes. As i need to use the resulting time in an php code snippet on button click i need to convert my code to php syntax to get the same result.

As example if time now is 15:17 the result should be 16:50

<SCRIPT>
    var today = new Date();
    today.setHours(today.getHours() + 1);
    today.setMinutes(today.getMinutes() + 30);
    var coeff = 1000 * 60 * 5;
    var date = "09:07:00";  //or use any other date
    var rounded = new Date(Math.round(today.getTime() / coeff) * coeff)
    var tid_1hour30min_from_now = rounded.toLocaleTimeString([], {hour: '2-digit', minute:'2-digit'});
    var tid_hour = rounded.getHours();
    var tid_minutes = rounded.getMinutes();
    var ater = "Åter"
    var result1hour30minfromnow = ater +" "+ tid_1hour_from_now
</SCRIPT>

So i would like to do the same but in php.

Been trying with simular code to this:

$startTime = date("Y-m-d H:i:s");
$cenvertedTime = date('Y-m-d H:i:s',strtotime('+1,5 
hour',strtotime($startTime)));

$current_time = strtotime($cenvertedTime);

$frac = 900;
$r = $current_time % $frac;

$new_time = $current_time + ($frac-$r);
$new_date = date('Y-m-d g:i:s A', $new_time);

But this doesn't turn out well, i newer get the same time in both script above. How can i translate the javascript as close as possible to php?

It can be done with "normal" date() function also.

$startTime = strtotime(date("Y-m-d H:i:s"))+90*60; // add 90 minutes times 60 seconds to UNIX time.
$NewMinute = round(date("i", $startTime)/5)*5; // find new minute by rounding on "5"

echo date("Y-m-d H:", $startTime) .str_pad($NewMinute, 2, "0", STR_PAD_LEFT);
