Really need help on this.

I would like to combine 2 variables into 1 new variable.

Example:
$total = 3
$Cnt = 0
$var1 = string1
$var2 = string2
$var3 = string3

While $total > $Cnt
$Cnt = $Cnt + 1
$newvar = $var + $Cnt <------
? $newvar
Loop

What i would like to have: $newvar should have result as $var1 where is "string1".

Actually, i would like to loop as many as $total variable defined and use $var1, $var2, $var3 when is looping.

Thanks in advance.
