Note Submitter: tomasz dot wasiluk at dnc dot pl Reason: 1 ---- To eduard dot ereza at blueit dot es: It's not about the position of the variable. You do not seem to know the basics of calling functions. Additionally switch your error level to E_ALL and display errors. You're example won't even work in the real world. Calling $z=foo($i) means you are passing $i as the $a parameter of the function definition. It's the equivalent of doing $z=foo($i, null, null, null, null, null, null, null, null) except it shouldn't work (can't pass null for a parameter by reference - I think this is being worked on though).
