note 77319 added to function.eval

This detects parse errors without executing the code: <?php function eval_syntax($code) { $b = 0; foreach (token_get_all($code) as $token) { if ('{' == $token) ++$b; else if ('}' == $token) --$b; } if ($b) return false; // Unbalanced braces would break the eval below else { ob_start(); // Catch potential parse error messages $code = eval('if(0){' . $code . '}'); // Put $code in a dead code sandbox to prevent its execution ob_end_clean(); return false !== $code; } } ?> ---- Server IP: 217.174.196.197 Probable Submitter: 82.239.245.173 ---- Manual Page -- http://www.php.net/manual/en/function.eval.php Edit -- https://master.php.net/note/edit/77319 Del: integrated -- https://master.php.net/note/delete/77319/integrated Del: useless -- https://master.php.net/note/delete/77319/useless Del: bad code -- https://master.php.net/note/delete/77319/bad+code Del: spam -- https://master.php.net/note/delete/77319/spam Del: non-english -- https://master.php.net/note/delete/77319/non-english Del: in docs -- https://master.php.net/note/delete/77319/in+docs Del: other reasons-- https://master.php.net/note/delete/77319 Reject -- https://master.php.net/note/reject/77319 Search -- https://master.php.net/manage/user-notes.php
