Variable Help

[vhaxu]

I need help combining variables.

 

$foo = "bar";
$bar = "10";

 

How do I easily make $foo = 10? (I have to do this with about a hundred variables)

The simplest way is

<?php
$foo = 'bar';
$bar = 10;
$foo = $bar;
?>

 

Or you can use variable variables

<?php
$foo = 'bar';
$bar = 10;
$foo = $$foo;
echo $foo;
?>
