How can i write this as a while loop? PHP

July 25, 2022

<?php
for ($i=0; $i<10; $i++) {
    $number = mt_rand(1, 100);
    if ($number %2== 0) {
        $result = 'even';
    } else {
        $result = 'odd';
    }
    echo $number.' '.'('.$result.')'.'<br>';
}?>

I want to write it in a while loop form
this is as far as i have gotten. It just prints one random number and nothing else. I am using phpStorm and edge browser on PHP8.1.

<?php

$i=0;
while ($i<10) {
  if ($number=mt_rand(1,100)) {
    $result = 'even';
  } else {
    $result = 'odd';
  }
  $i++;
  echo $number.' '.'('.$result.')'.'<br>';
}
    
?>

>Solution :

The main reason that the code is not working is that you are assigning the $number = mt_rand(1,100) inside the if() condition.

So everytime you execute if then it will not compare but it’ll keep assigning the $number variable. I have separated the assignment and comparison logic.

Try This:

<?php

    $i=0;
    while ($i<10) {
        $number = mt_rand(1,100);
        if ($number % 2 == 0) {
            $result = 'even';
        } else {
            $result = 'odd';
        }
        $i++;
        echo $number.' '.'('.$result.')'.'<br>';
    }
