note 103698 added to language.types.string

Jeff's code, for evaluating php expressions within strings, contains errors (a misusage of eval and a missing = character) but the concept is good -- thanks for that. Here is a corrected version that should get the job done: <?php //Ultimater at gmail dot com's revision of jeff at kingdesk dot com's code $eval='evaluate'; function evaluate($str) { return eval("return $str;"); } echo "2 + 2 = {$eval('2+2')}"; ?> Note that I renamed the function to $eval rather than the desperate looking $e->val. ---- 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/103698 Del: integrated -- https://master.php.net/note/delete/103698/integrated Del: useless -- https://master.php.net/note/delete/103698/useless Del: bad code -- https://master.php.net/note/delete/103698/bad+code Del: spam -- https://master.php.net/note/delete/103698/spam Del: non-english -- https://master.php.net/note/delete/103698/non-english Del: in docs -- https://master.php.net/note/delete/103698/in+docs Del: other reasons-- https://master.php.net/note/delete/103698 Reject -- https://master.php.net/note/reject/103698 Search -- https://master.php.net/manage/user-notes.php
