Another random number question

Let's say $mynum = 3. What function can give me a random number from 1-99 except the current value of $mynum? Noob here (obviously).

 

<?php

$mynum = rand(1,99);
echo $mynum;

?>

PHP:

 

Or something like this:

$num = rand(1,99);
while($num == $mynum){
$num = rand(1,99);
}
$mynum = $num;

echo $mynum.


Other option is to use an array: $arr = range(1,99); $mynum = $arr[rand(1,99)];

 

<?php
$mynum = 3;
$rand =  rand(1,99);
if($rand == $mynum)
{
$rand = rand(1,99);
}

echo $rand;
?>

Code (markup):

that should be what you want

 

My mistake: while($num == $mynum)
