Here is a tip on using $GLOBALS. If you set an element of the $GLOBALS array equal to an array, you might have problems calling those variables. Below is an example. //declare array $list = array("ex1"=> "example1", "ex2"=> "example2"); //set example element of GLOBALS array equal to lis array $GLOBALS[example] = $list; //Now if you try to print print $GLOBALS[example][ex1]; //You get "example1" returned //as expected //But id you try to print //the same thing, but enclosed //in double quotes print "$GLOBALS[example][ex1]"; //You get "Array[ex1]"; //Enclosing in double quotes //somehow screws up the expansion //of that variable //You must instead print "{$GLOBALS[example][ex1]}"; //enclose the variable in curly braces //this returns "example1" as expected;
