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; }
