PHP - The "&" symbol

gregerly
192 Expert 100+
Hello All,

In PHP, what does the "&" syntax mean? An example of this is:

[PHP]$_POST = &$HTTP_POST_VARS;[/PHP]

I'm not so much concerned with the other parts of the above line except the "&" symbol.

Thanks

This is called reference. For detailed info look at PHP Manual.

If you still unable to understand, please post back.

To echo mwasif's advice:
References can be *very* confusing. If you have any questions, feel free to post back anytime :)
