note 103697 added to language.types.string

I'm having trouble getting jeff at kingdesk dot com's code to work -- PHP's eval function is slightly different from what you learn in JavaScript's -- although the concept is good. $e->val can also be replaced with $eval like so: <?php $eval='evaluate'; function evaluate($str) { return eval("return $str;"); } echo "2 + 2 = {$eval('2+2')}"; ?> ---- Server IP: 69.147.83.197 Probable Submitter: 76.90.130.197 ---- Manual Page -- http://www.php.net/manual/en/language.types.string.php Edit -- https://master.php.net/note/edit/103697 Del: integrated -- https://master.php.net/note/delete/103697/integrated Del: useless -- https://master.php.net/note/delete/103697/useless Del: bad code -- https://master.php.net/note/delete/103697/bad+code Del: spam -- https://master.php.net/note/delete/103697/spam Del: non-english -- https://master.php.net/note/delete/103697/non-english Del: in docs -- https://master.php.net/note/delete/103697/in+docs Del: other reasons-- https://master.php.net/note/delete/103697 Reject -- https://master.php.net/note/reject/103697 Search -- https://master.php.net/manage/user-notes.php
