note 71170 added to language.references.arent

I needed a function to set a few globals for me. The globals had very long names (to be somewhat unique), so the function started to look really ugly. Using a reference helped me to clean up the code a little. Here's an interesing way of using references with globals - in a bit of a 'pointer-like' way. <? function f1() { global $g_B, $g_C; $v =& $g_B; $v = 91; $v =& $NULL; $v =& $g_C; $v = 45; $v =& $NULL; } f1(); echo $g_B . ", " . $g_C; ?> The result is: 91, 45 Btw, does it really matter how much the references are like or unlike pointers? As long as they work... :) ---- Server IP: 66.163.161.117 Probable Submitter: 217.30.156.35 ---- Manual Page -- http://www.php.net/manual/en/language.references.arent.php Edit -- https://master.php.net/note/edit/71170 Del: integrated -- https://master.php.net/note/delete/71170/integrated Del: useless -- https://master.php.net/note/delete/71170/useless Del: bad code -- https://master.php.net/note/delete/71170/bad+code Del: spam -- https://master.php.net/note/delete/71170/spam Del: non-english -- https://master.php.net/note/delete/71170/non-english Del: in docs -- https://master.php.net/note/delete/71170/in+docs Del: other reasons-- https://master.php.net/note/delete/71170 Reject -- https://master.php.net/note/reject/71170 Search -- https://master.php.net/manage/user-notes.php
