Description: ------------ Since php 5.4 you should not have function __construct and old type constructor - method name same as class - HTML_CSS() in one class. When you do, php generates warning - Redefining already defined constructor for class HTML_CSS I suggest just to delete old type constructor - function HTML_CSS($attributes = array(), $errorPrefs = array()) I found old report here - https://pear.php.net/bugs/bug.php?id=16255 Can you create new major version and fix this issue please? Test script: --------------- require_once 'HTML/CSS.php'; new HTML_CSS(); Expected result: ---------------- No PHP warning is generated. Actual result: -------------- PHP Notice: Redefining already defined constructor for class HTML_CSS
