by my template engine
to avoid ugly error messages i won't to prepend these lines
if (!isset($_SERVER['DOCUMENT_ROOT'])) $_SERVER['DOCUMENT_ROOT'] = NULL;
if (!isset($data['eine_variable'])) $data['eine_variable'] = NULL;
if (!defined('DIRECTORY_SEPARATOR')) define('DIRECTORY_SEPARATOR', NULL);
if (!defined('__FILE__')) define('__FILE__', NULL);
Suppressing error message by using error_reporting(0); is no option becuase it slows down the code (error still occurs, php looks for an error handler, ...)
So I need to detect all vars and constants used in th etemplate.
I can look at the produced code and find anything starting with $.
This way I don't find any constants used.
I can look at the template and search for anything between { and }
This way I get everything except DIRECTORY_SEPARATOR, cause it's not used as a "plain" constant but it's ued in an if-statement.
So where and how do I find the two vars and the two constants used?
In the template? If so: How?
In the produced code? If so: How?
