change variable name in a foreach

Question

How can I change the $rank variable name to $rank1, $rank2 and so on depending on the user $userID?

foreach($myClient as $users){
   $username = $users->usrnm;
   $userID = $users->usrID;
   $rank...
   
}

Using numbered variables is usually a good sign that using an array is a better solution. — Nigel Ren, Aug 01 '21 at 18:31
What exactly are you trying to achieve and what's in `$myClient`? — digijay, Aug 01 '21 at 18:35
Dynamic variable naming is bad. Why do you need this anyway? — nice_dev, Aug 01 '21 at 18:45

@nice_dev Can you explain to me why dynamic variables is a bad thing? — Marcel, Aug 01 '21 at 19:00
@Marcel Ok, if you create dynamic variables, can you assure $rank465 exists always, to use it in your code? There are other reasons too though. — nice_dev, Aug 01 '21 at 19:07

You can do like this:

$userId1 = 1;
$userId2 = 2;

$rankVarName1 = sprintf('rank%s', $userId1);
$rankVarName2 = sprintf('rank%s', $userId2);

$$rankVarName1 = 'rank var value';
$$rankVarName2 = 'other rank';

var_dump($rank1); // rank var value
var_dump($rank2); // other rank

but I recommend you use an array

$ranks = [];

$userId1 = 1;
$userId2 = 2;

$ranks[$userId1] = 'rank var value';
$ranks[$userId2] = 'other rank';

var_dump($ranks[$userId1]); // rank var value
var_dump($ranks[$userId2]); // other rank
