PHP OOP Function Syntax

[OhNoMrBill]

What does the _ and & prefix mean when applied to php functions/variables?

ex:
public function &myVariable() {
$myVariable = &someFunction($someParam);
return $myVariable;
}

Thanks!

Welcome to WebmasterWorld!

The ampersand (&) before a variable makes it a reference. More here: references explained [us2.php.net].

The double underscore (__) before the function identifier can have a couple different meanings. I suggest that you read some of the documentation on classes: Classes and Objects (PHP5) [us2.php.net].

Thanks. The variable aspect makes perfect sense. Having a little trouble getting my head around function names declared as references. What is that intended to do?

Thanks again!

It allows you to pass a function argument by reference [php.net]
