round down to nearest 5 mintues php mysqli - php

Question

I"m trying to get this time code to round down to the nearest time
example if the time listed is 10:28, then i want it to show 10:25
What I have is (the time modify is required)
<?php
include('../../database/2ndconnection.php');
$sql="SELECT * FROM raid ORDER BY TimeRecord DESC LIMIT 1";
$result=mysqli_query($dbcon,$sql);
while($rows=mysqli_fetch_array($result)){
$dateStr = $rows['TimeRecord'];
$pst = new \DateTime($dateStr);
$pst->modify("-3 hours");
$est = new \DateTime($dateStr);
} ?>
PST: <?php echo $pst->format('H:i'); ?>
<br>EST: <?php echo $est->format('H:i'); ?>
thanks in advance for your help

Answer 1

Insert this:
<?php
$currentMinutes = $time->format('i');
$minutesToSubtract = $currentMinutes % 5;
$time = $time->sub(new DateInterval('M' . $minutesToSubtract));
?>
$currentMinutes will hold the current number of minutes, using %, you can compute the minutes that need to be subtracted, and afterwards you subtract them through the sub function
It could be integrated into your code as following:
<?php
include('../../database/2ndconnection.php');
$sql="SELECT * FROM raid ORDER BY TimeRecord DESC LIMIT 1";
$result=mysqli_query($dbcon,$sql);
while($rows=mysqli_fetch_array($result)){
$dateStr = $rows['TimeRecord'];
$pst = new \DateTime($dateStr);
$pst->modify("-3 hours");
$est = new \DateTime($dateStr);
}
$currentMinutes = $pst->format('i');
$minutesToSubtract = $currentMinutes % 5;
$pst = $pst->sub(new DateInterval('M' . $minutesToSubtract));
?>
PST: <?php echo $pst->format('H:i'); ?>
<br>EST: <?php echo $est->format('H:i'); ?>
