Re: RE: session

Regarding the proposed reasoning for it not working from Tim, I find conflicting evidence. For example, try this : $a = array('a','b','c'); foreach ($a as $key => $value) { $a[$key] = $value . $key; } print_r($a); The array does indeed change. It does work on a copy but one still can modify it if one decides to, as demonstrated above. Perhaps a kind soul can explain the meaning of it "working on a copy" as described in the manual with an example on why it matters (possible mishaps). Regarding why negative numbers remain (your array not changing), read the user comments found here : http://www.php.net/manual/function.session-register.php Many discuss this very topic. In fact, this issue looks to be the most popular form of user comment.
