note 82864 added to language.types.array

Using variables as array names no longer works in PHP5. $fum = "somevar"; $foo = $$fum; # Still works if $somevar isn't an array. $foo contains the value of $somevar but .... $fum = "_POST"; print_r($$fum); print_r(${$fum}); Neither form of indirection works in this context. $$fum comes back empty. If you have PHP4 code that used this kind of indirection you can work around the change in PHP5 using an eval(). $fum = "_POST"; $foo = eval("return $$fum;"); print_r($foo); This works! ---- Server IP: 64.71.164.2 Probable Submitter: 70.112.242.197 ---- Manual Page -- http://www.php.net/manual/en/language.types.array.php Edit -- https://master.php.net/note/edit/82864 Del: integrated -- https://master.php.net/note/delete/82864/integrated Del: useless -- https://master.php.net/note/delete/82864/useless Del: bad code -- https://master.php.net/note/delete/82864/bad+code Del: spam -- https://master.php.net/note/delete/82864/spam Del: non-english -- https://master.php.net/note/delete/82864/non-english Del: in docs -- https://master.php.net/note/delete/82864/in+docs Del: other reasons-- https://master.php.net/note/delete/82864 Reject -- https://master.php.net/note/reject/82864 Search -- https://master.php.net/manage/user-notes.php
