Could you give me a good example of the tip you recommend or point me to a good tutorial on it?

$GLOBALS holds all variables defined in main(), main() meaning outside any function or class //main() $my_var = 'test'; function myFunction() {

    echo $GLOBALS['my_var'];

    // is the same as:
    global $my_var
    echo $my_var;

    // 'global' just creates a local reference to the global variable
    // global $my_var; is the same as:
    $my_var =& $GLOBALS['my_var'];
    echo $my_var;
