Question

Answer 1

As far as I am aware using different variable names is not possible.

However if you uses arrays so as below

$xm[3] = "";
$xm[2] = "";
$xm[1] = "";
$xm[0] = "";

or just $xm[] = "";

Then you can use a for each loop:

foreach($xm as $v) { echo $v; }

Edit: Just Googled and this is possible using variable names but is considered poor practice. Learn and use arrays!
