value of variable in a variable

[kanakana]

$var1=10;
$var2="var1";

now how can i get the value 10 from $var1 to $var3 interms of $var2.

like $var3=$$var2
but the above statement only outputs $var1 not 10;


TIA

Could you explain what you mean by "$var1 to $var3 interms of $var2."

A shoot in the dark as i don't fully understand what you need  ::) :
[code]
<?php

$var1 = 10;
$var2 = $var1;    // $var2 = 10
$var3 = $var2;    // $var3 = 10

?>
[/code]
