Re: bug when using foreach with references?

I don't follow. Is this really the intended behavior? It seems quite unintuitive that the original array would be modified by *empty* loops. Suppose I create an include file that loops through $_GET variables with references: foreach ($_GET as &$get) { /* empty loop */ } Subsequent foreach() loops on $_GET would cause corruption. Seems dangerous. When would this behavior be desired? !intuitive && !desired == bug ? Richard On Oct 21, 2009, at 8:19 PM, mm w wrote:

Richard, enumerator exhausted, repeat your sub-sequence again you will get it e.g pointer and pointed

<?php $items = array('apple', 'banana', 'carrot'); print_r($items); foreach ($items as &$item) { } print_r($items); foreach ($items as $item) { } print_r($items);
