note 99496 added to language.references.whatdo

In reply to Drewseph with php4 I also got "hello hello" in your example. So I doubt the expression values of $a = 'set' in php4 and php5 are different. Example: <?php function foo(&$bar) { $bar = "hello\n"; } foo($unset); echo($unset); foo($set = "set\n"); echo($set); ?> Output: hello hello ---- Server IP: 69.147.83.197 Probable Submitter: 126.112.211.154 ---- Manual Page -- http://www.php.net/manual/en/language.references.whatdo.php Edit -- https://master.php.net/note/edit/99496 Del: integrated -- https://master.php.net/note/delete/99496/integrated Del: useless -- https://master.php.net/note/delete/99496/useless Del: bad code -- https://master.php.net/note/delete/99496/bad+code Del: spam -- https://master.php.net/note/delete/99496/spam Del: non-english -- https://master.php.net/note/delete/99496/non-english Del: in docs -- https://master.php.net/note/delete/99496/in+docs Del: other reasons-- https://master.php.net/note/delete/99496 Reject -- https://master.php.net/note/reject/99496 Search -- https://master.php.net/manage/user-notes.php
