What's the difference? Should I always be using =&, does = use more memory? |

Should I always be using =& No.
does = use more memory? Well, sort of. =& means 'assign a reference', whereas = is 'assign the value' (so you're therefore copying it). They have different uses so use the one that you need  . |

Indeed.
$a = 1;
$b =& $a;
$a = 2;
echo $b;
Will output 2, which might not always be what you're after. |

Erm, what I meant to ask was about $a=new Blah() and $a=&Blah() -- what exactly happens which each of those? And how come a mysterious bug disappeared when I changed = to =& ?  |

I'm referencing the right object, I just don't understand these pesky references properly |

. Still no answers Well, to be fair, you haven't asked a question that's particularly easy to answer without access to the source code, and what exactly you're doing.
http://www.php.net/manual/en/language.references.return.php seems to maybe be relevant, along with the whole of the references section - I don't think you want to be using references unless you know exactly what you're doing with them. |

Well, the problems I'm experiencing are to do with variables set after calling the constructor. Under certain circumstances, when the object gets copied (yeah, I know, that's too vague), the variables initialised in the constructor are preserved, but those set after object construction are undefined.
Perhaps I'll try a PHP forum or sommit. |

Yes, that's the idea. It does exist, you know 
No links though, because the official site is still in pieces |
