i wonder where i should put the & properly.
$b =& $a;
or
$b = &$a;

A:
Both reference the same thing, just a matter of coding style.
Personally, I prefer the $b = &$a style for readability, the space from the & and $ throws me off.

I personally prefer the first way. `$b =`

@Aistina very true. Good enough reason to change my preference.

Better how? And in whose opinion? They both do the same thing, "better" is a point of view. -1

This is actually up to you.
I would, like most others, put the & directly before the $ sign of the variable - it makes the code easier to read in my opinion.

A:
Put it where the code convention you use tells you to put it.
The PHP manual on references uses =& exclusively, whereas the PHP manual on variables states
To assign by reference, simply prepend an ampersand (&) to the beginning of the variable which is being assigned (the source variable).
