[snip] I'm helping someone out with some PHP code, and I keep seeing them using the operator "=&", which AFAIK is not a PHP operator... but it seems to work fine, as though it were a simple assignment operator (i.e. "="). Before I go telling him that he shouldn't be using it (for the sake of code readability, at least), does someone know of some obscure part of the PHP docs that mentions this operator? Or perhaps he's confusing it with an operator from some other language? [/snip] http://www.php.net/manual/en/language.references.php#language.references .whatare
