Are you want dynamic variable or just a normal variable which will give you the out put like
12345678910

<?php 
$var=10;
$a='';
for($i=1;$i<=$var;$i++){
$a.=$i;
}
echo $a;
?>

output: http://3v4l.org/2p8L6

or if you want dynamic variable then use following code to make a variable dynamic

${"num_" . $i} = $i;

output will be 

$num_1=1; 
$num_2=2;
$num_3=3;

etc

In plain English; PHP is updating the value stored in lopping variable automatically, and this is the whole idea behind using for loops, not only in PHP, but also in other programming languages.

Usually, you would want to use it (the variable $i) as a kind of a counter, and run code in the loop based on the iteration count.
