create a debug function (public) and use get_class. call that in the
debug function. when u want to do the debugging, use it with the obj
as parameter, maybe $this will work when u're in the class, otherwise,
use the object aka class instance variable.
u may wanna pass by reference and make it const (won't have to use
more memory for it...since it's task with it is small and read-only)
from http://php.net/get_class

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
