获取在PHP中运行函数/类的文件的名称

Question

Is there any way to find out which file runs function/class in PHP.

I have index.php which includes functions/classes, than it includes other files depending on url. I wish to know which file runs function/class for debugging.

For example I have MySql class and I what to know which file used this class.

One option is to type the file name in function like $sql->do($cmd,$fileName) , but there are too many files so I can't change all them.

See debug_backtrace .

In your MySql class you can simply call this function, and trace the call to it's origin.
