PHP List, I have a list of variables: $001 $002 $003 $004 And what I'd like to do is have a function which will select and return one of them. Something like: public function returnVar($n) { return $(somehow n is made to reference the name of the variable); } And then in later scripts I can call anyone of the variables by saying returnVar(001)

Or something like that.

I've been scratching my head on how to do this for a while. I thought the answer might lie somewhere in call_user_func(), but even if it is I can't determine how. Any advice would be much appreciated.

<?php function easy_peasy( $name ) {

    $foo1 = 1;
    $foo2 = 2;
    $foo3 = 3;

    return $$name;

} echo easy_peasy( 'foo2' )."\n"; ?> Cheers, Rob.

Or something like that. <---- :-)

$easy_peasyier = array("foo1" => 1, "foo2" => 2, "foo3" => 3); echo($easy_peasyier['foo1']); tedd -- ------- http://sperling.com http://ancientstones.com http://earthstones.com
