Php By Reference

Question

Can someone please explain what the \"&\" does in the following:

class TEST {

}

$abc =& new TEST();

I know it is by reference. Bu

Answer 1

The PHP Manual does a pretty decent job of explaining references.

I should note, that they are NOT the same thing as a pointer or a reference in many other languages, although there are similarities. And as for objects being "passed by reference" by default - that's not exactly true either.

I would recommend reading the manual section first (and probably then re-reading a couple of times until you get it), and then come back here if you still have more questions.
