Debug

Provides the ability to see debug messages for deprecated functions, malformed documents and parsing issues. Debug messages can be send to a custom message handler or written to error_log (default).

Example

<?php
include_once 'HtmlDocument.php';
include_once 'Debug.php';
use simplehtmldom\HtmlDocument;
use simplehtmldom\Debug;

Debug::enable();

$dom = new HtmlDocument();
$dom->load('<html></html>');
$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."
