note 32952 added to function.eval

eval() returns FALSE if a fatal error occurs. For this reason, you should never return() a FALSE value from eval()'d code or else you will lose the distinction between FALSE and FATAL. Note also that if you have installed a custom error handler, with set_error_handler(), it will NOT be used to handle errors inside your eval() statement. You can call eval("set_error_handler('myErrorHandler'); //...") but Parse and other Fatal errors that NEVER are passed to a custom error handler will still always result in FALSE being returned from eval(). Sample code: <?php // FILE: test/test.php $x=eval(";"); echo "Default Return Value: "; if($x===FALSE) echo "FALSE\n"; if(is_null($x)) echo "NULL\n"; $x=eval("<?"); echo "Fatal Error Returns: "; if($x===FALSE) echo "FALSE\n"; if(is_null($x)) echo "NULL\n"; ?> OUTPUT: $ php test/test.php Default Return Value: NULL PHP Parse error: parse error in /usr/local/apache/htdocs/common/php/xmake_org/xobj/test/test.php(6) : eval()'d code on line 1 Fatal Error Returns: FALSE ---- Manual Page -- http://www.php.net/manual/en/function.eval.php Edit Note -- http://master.php.net/manage/user-notes.php?action=edit+32952 Delete Note -- http://master.php.net/manage/user-notes.php?action=delete+32952&report=yes Reject Note -- http://master.php.net/manage/user-notes.php?action=reject+32952&report=yes
