note 65363 added to language.variables.variable

i think there was a comment about dynamically globalizing a var, but heres an example of using it for unsetting array keys. function unsetkeys($name=FALSE,$keys=FALSE){ global ${$name}; foreach($keys as $key){ unset(${$name}[$key]); } } // set an array. blah. $colors=array('cold'=>'blue', 'warm'=>'yellow', 'blah'='>stupid'); // remove cold and warm unsetkeys('colors',array('cold','warm')); // should output "blah => stupid" print_r($colors); ---- Server IP: 64.71.164.2 Probable Submitter: 71.71.211.240 ---- 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.variable.php Edit -- http://master.php.net/note/edit/65363 Del: integrated -- http://master.php.net/note/delete/65363/integrated Del: useless -- http://master.php.net/note/delete/65363/useless Del: bad code -- http://master.php.net/note/delete/65363/bad+code Del: spam -- http://master.php.net/note/delete/65363/spam Del: non-english -- http://master.php.net/note/delete/65363/non-english Del: in docs -- http://master.php.net/note/delete/65363/in+docs Del: other reasons-- http://master.php.net/note/delete/65363 Reject -- http://master.php.net/note/reject/65363 Search -- http://master.php.net/manage/user-notes.php
