Hi I am trying to work out this problem where I need to make a infinite while loop generate random numbers between 1-10, where if the value is 5 it terminates, however any other number will output the cube root of that value.

This is what I have so far however I am new to PHP so I really don't know where to go from here to get the correct answer. Can anyone help me out?

while(true)
{
$counter = rand(1, 10);   
    if ($counter <=10) {
        echo sqrt($counter) . "</br>";
    }
if($counter ==5) break;
}

while(true) {
   $i = rand(1, 10);
   if($i != 5) {
      echo sqrt($i);
   }
}

This would be how I'd do it.

There is a syntax error on that code for me bro. Around the rand function.

Okay I fixed the syntax, however with your code, the web browser is very slow because of the loop. Is there any way to make it hit 5 quicker to terminate?

Shouldn't be. I tested it and it works fine lol.

Only thing different is I added the <br/> to make it on a different line.

OH I miss understood what you were asking for haha. One second I'll fxi my code up.

Edit:
This would work
<?php
$a = true;
while($a == true) {
   $b = rand(1, 10);
   if($b != 5) {
      echo sqrt($b) .'<br/>';
   }
   else {
      $a = false;
   }
}
?>

No problem at all.

As for how good I am? I've been doing it for a few years and have picked up a few tricks here and there. I'm not gonna say I'm the best, but I definitely know how to do ALMOST anything.

This will run in an "infinite" loop until the random number is 5.
little bit shorter than ryzen's

$not5 = true;
while($not5){
    $i = rand(1,10);
    if ($i == 5) $not5 = false;
    echo sqrt($i);
}
