note 82866 added to language.variables.variable

You can use eval() to get around the limitation on using variable variables to reference superglobal arrays. e.g.: # this fails: function indir($name) { $moe = $$name; echo "<pre>"; print_r($moe); echo "</pre>"; } indir("_SERVER"); # this works :-) function indir($name) { $moe = eval("return \$$name;"); echo "<pre>"; print_r($moe); echo "</pre>"; } indir("_SERVER"); ---- Server IP: 64.71.164.2 Probable Submitter: 70.112.242.197 ---- Manual Page -- http://www.php.net/manual/en/language.variables.variable.php Edit -- https://master.php.net/note/edit/82866 Del: integrated -- https://master.php.net/note/delete/82866/integrated Del: useless -- https://master.php.net/note/delete/82866/useless Del: bad code -- https://master.php.net/note/delete/82866/bad+code Del: spam -- https://master.php.net/note/delete/82866/spam Del: non-english -- https://master.php.net/note/delete/82866/non-english Del: in docs -- https://master.php.net/note/delete/82866/in+docs Del: other reasons-- https://master.php.net/note/delete/82866 Reject -- https://master.php.net/note/reject/82866 Search -- https://master.php.net/manage/user-notes.php
