Provides the ability to see debug messages for deprecated functions, malformed documents and parsing issues. Debug messages can be sent to a custom message handler or written to error_log (default). ## Example ```php load(''); $dom->root->children(); // This causes a deprecation warning Debug::disable(); ``` **Output** ``` [DEBUG] [/var/www/html/simplehtmldom/Debug.php:30] [/var/www/html/simplehtmldom/test.php:7] "Debug mode has been enabled" [DEBUG] [/var/www/html/simplehtmldom/HtmlNode.php:83] [/var/www/html/simplehtmldom/test.php:11] "simplehtmldom\HtmlNode->children() has been deprecated and will be removed in the next major version of simplehtmldom. Use simplehtmldom\HtmlNode->childNodes() instead." [DEBUG] [/var/www/html/simplehtmldom/Debug.php:38] [/var/www/html/simplehtmldom/test.php:13] "Debug mode has been disabled" ```
