note 81376 added to function.eval

If you attempt to call a user defined function in eval() and .php files are obfuscated by Zend encoder, it will result in a fatal error. Use a call_user_func() inside eval() to call your personal hand made functions. This is user function <?php function square_it($nmb) { return $nmb * $nmb; } ?> //Checking if eval sees it? <?php $code = var_export( function_exists('square_it') ); eval( $code ); //returns TRUE - so yes it does! ?> This will result in a fatal error: PHP Fatal error: Call to undefined function square_it() <?php $code = 'echo square_it(55);' ; eval( $code ); ?> This will work <?php $code = 'echo call_user_func(\'square_it\', 55);' ; eval( $code ); ?> ---- Server IP: 69.147.83.197 Probable Submitter: 82.193.208.173 ---- Manual Page -- http://www.php.net/manual/en/function.eval.php Edit -- https://master.php.net/note/edit/81376 Del: integrated -- https://master.php.net/note/delete/81376/integrated Del: useless -- https://master.php.net/note/delete/81376/useless Del: bad code -- https://master.php.net/note/delete/81376/bad+code Del: spam -- https://master.php.net/note/delete/81376/spam Del: non-english -- https://master.php.net/note/delete/81376/non-english Del: in docs -- https://master.php.net/note/delete/81376/in+docs Del: other reasons-- https://master.php.net/note/delete/81376 Reject -- https://master.php.net/note/reject/81376 Search -- https://master.php.net/manage/user-notes.php
