如何在foreach循环运行的每50次增加一个值1

Question

How can I increment a value in a foreach loop for every 50 times the loop runs.

<?php

$counter = 1; 
foreach ($numbers as $num) {
      //For the first 50 times the loop runs, $counter = 1. For every 50 runs, increment by 1
$counter = 1;

//if loop has run more than 50 times, increment $counter to 2 


}
?>

        <?php 
    $counter = 0;
    $value = 50; // Intial position
    $numbers = 230 // Lets say you have total 230 iterations.
    for ($i = 0 ; $i <= $numbers ; i++)
    {
     if($i == $value) // if 50 counter is increased and we are setting the value to 100
{
$counter += 1;
$value = $value * 2;
}
}
