Note Submitter: kieran@kieran.ca ---- I ran across something that should be noted... Take care when using variables for referencing arrays. PHP will interpret the square bracket syntax [] as a substr() like reference.... <? // this doesn't work, PHP evaluates $($foo[$bar]) instead of ($$foo)[$bar] $temp = $$foo[$bar]; /*--------------------------------------------------------*/ // use this method instead: // make a temp array so we can refer to it by an absolute name $temp_array = $$foo; // now pull the value $temp = $temp_array[$bar]; ?> Cheers!
