Arrays and varialbles

[llebron]

I'm trying to get the following code to work:
<?php
$resp_id=array(1, 5, 7, 9, 11);
$resp_id_1=array(1, 3, 4, 5);

//This works
$temp=$resp_id_1;
print_r($temp);

//This doesn't work
$i=0;
$temp="\$resp_id_".$resp_id[$i];
print_r($temp);

?>

Can someone tell me why the last three lines of code do not work correctly?

thanks,

Luis

${'resp_id'.$resp_id[$i]}

think that should do it

//This does work
$i=0;
$temp="resp_id_" . $resp_id[$i];
print_r($$temp);
