create a debug function (public) and use get_class. call that in the

if you're using php5 all objects are references, pass-by-reference occurs whether you like it or not (unless you specifically use 'clone') ...also a constant (global or class scope) cannot be set to an object. I'm still very curious as to how Yangshiqi intends to use his DebugHelper class! (apologies if I have written your name incorrectly.)

more memory for it...since it's task with it is small and read-only) from http://php.net/get_class [quote] Example 1. Using get_class() <?php class foo { function foo() { // implements some logic } function name() {

       echo "My name is " , get_class($this) , "\n";

} } // create an object $bar = new foo(); // external call echo "Its name is " , get_class($bar) , "\n"; // internal call $bar->name(); ?> The above example will output: Its name is foo My name is foo [/quote]
