Question

How to do the same operation until it reaches one condition?
For Example:

<?php
  $n = rand(5,157);
  if ($n=='63'){
    echo 'ok';
  } else {
    //* another random, until rand () will give 63  *//
  }
?>

how can I fix this? Thanks in advance!

Answer 1

You need to use while loop:

<?php
  $n = rand(5,157);
  while ($n != 63) {
    $n = rand(5,157); // n is not 63, get another number
  }

  echo 'ok';
?>

if will check for condition once, whereas while will check condition until it is not true
