note 63586 added to language.variables

I had an application for this a while back and couldn't find a solution and ended up spending a while testing things myself until I found a solution. I'm adding this for Google's sake so that others can find it. I searched for: dynamic variables, using contents of variable as variable name, declaring variables as variable names, etc. So here's what I got: <?php $foo = "bar"; ${$foo} = "goo"; echo $bar; ?> This example set the variable $foo to "bar"... then declares a new variable from the contents of $foo and sets its value to "goo"... effectively that line translates to $bar = "goo". then I output the value of $bar just to prove the point and its works as assumed... it prints "goo"... Hope that helps someone else out! ---- Server IP: 64.71.164.2 Probable Submitter: 69.29.51.66 ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/language.variables.php Edit -- http://master.php.net/note/edit/63586 Del: integrated -- http://master.php.net/note/delete/63586/integrated Del: useless -- http://master.php.net/note/delete/63586/useless Del: bad code -- http://master.php.net/note/delete/63586/bad+code Del: spam -- http://master.php.net/note/delete/63586/spam Del: non-english -- http://master.php.net/note/delete/63586/non-english Del: in docs -- http://master.php.net/note/delete/63586/in+docs Del: other reasons-- http://master.php.net/note/delete/63586 Reject -- http://master.php.net/note/reject/63586 Search -- http://master.php.net/manage/user-notes.php
