note 126715 added to function.eval

to avoid the evil eval() you may use the fact that function names, variable names, property names and method names can be handled strings. <?php class Fruit { public $tomato = "Tomatos"; public function red() {return " are red. ";} } $fruit = new Fruit; $fruitStr = "tomato"; $colorStr = "red"; echo $fruit->$fruitStr . $fruit->$colorStr(); // and procedural ////////////////////////////////////////// $lemon = "Lemons"; function yellow() {return " are yellow. ";} $fruitStr = "$lemon"; $colorStr = "yellow"; echo $fruitStr . $colorStr(); ?> ---- Server IP: 45.112.84.4 Probable Submitter: 80.90.5.135 (proxied: 217.100.185.202) ---- Manual Page -- https://php.net/manual/en/function.eval.php Edit -- https://main.php.net/note/edit/126715 Del: integrated -- https://main.php.net/note/delete/126715/integrated Del: useless -- https://main.php.net/note/delete/126715/useless Del: bad code -- https://main.php.net/note/delete/126715/bad+code Del: spam -- https://main.php.net/note/delete/126715/spam Del: non-english -- https://main.php.net/note/delete/126715/non-english Del: in docs -- https://main.php.net/note/delete/126715/in+docs Del: other reasons-- https://main.php.net/note/delete/126715 Reject -- https://main.php.net/note/reject/126715 Search -- https://main.php.net/manage/user-notes.php
