note 49466 added to language.variables.variable

in response to "pear at inkas dot it" ${$_SESSION['var_name']} does work. What doesn''t work is something like this: <?php // consider file has been called with ?var=val function test() { $val = '_GET'; var_dump($$a); echo "\n"; var_dump(${$_GET['var']}); } test(); ?> will output NULL string(4) "_GET" the use of $$a inside a function or method will not reference the superglobal ever, but instead look for a local variable $_GET, which will never exist, even if you try to create one by doing something like "$_GET = array();" inside the function. setting "global $_GET" inside the function won't work also. You simply can't create a reference to a superglobal inside a function or method by trying to access it via a variable variable. ---- Manual Page -- http://www.php.net/manual/en/language.variables.variable.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+49466 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+49466&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+49466&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+49466&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+49466&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+49466&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+49466&report=yes Search -- http://master.php.net/manage/user-notes.php
