Question

This is my code;

$script = $row['script']; 

   // $row is from database and the $row['script'] is exeactly the same with $script commented below.
  // $script ="global \$timedate;\$target =\$timedate->now();return \$target;";

return eval($script);

When I uncomment the $script, it will run correctly. However, if I commnent $script and load the value from $row[‘script’], the eval get error below:

 [12-May-2012 22:09:25 UTC] PHP Parse error:  syntax error, unexpected $end in C:\Users\iopen\Documents\IOPEN\Project\Clients\sugarcrm\hfcrmlocal\custom\modules\iopenwf\model\IOpenAction.php(56) : eval()'d code on line 3

Any idea?

Don’t use eval its a very bad idea.

For experimenting purpose you can use stripslashes to remove most slashes issues

class Test {
    function now() {
        return time ();
    }
}

$timedate = new Test ();
$script = "global \$timedate;\$target =\$timedate->now();return \$target;";
$script = stripslashes ( $script );
var_dump ( eval ( $script ) );
