PHP Simple HTML DOM Parser - an Intoduction

PHP Simple HTML DOM Parser, is one of the easiest DOM manipulation script written in PHP5+. Being Open source, it is free to use under the MIT License. Supporting invalid HTML, this parser is better then other PHP scripts that use complicated regexes to extract information from web pages. It helps to find tags on an HTML page with selectors just like jQuery.

htmLawed is a highly customizable single-file PHP script to make text secure, standard and admin policy-compliant for use in the body of HTML 4, XHTML 1 or 1.1, or generic XML documents. It is thus a configurable input (X)HTML filter, processor, purifier, sanitizer, beautifier, etc., and an alternative to the HTMLTidy application.

The lawing in of input text is needed to ensure that HTML code in the text is standard-compliant, does not introduce security vulnerabilities, and does not break the aesthetics, design or layout of web-pages. htmLawed tries to do this by, for example, making HTML well-formed with balanced and properly nested tags, neutralizing code that may be used for cross-site scripting (XSS) attacks, and allowing only specified HTML elements/tags and attributes

Most the times I have noticed the beginners are confused in testing the variable, whether it contains some data or not.

While it is important to be checking values, it is equally important to understand the difference between the different methods of checking and testing values for empty, null, or if they are set.

The following difference chart between "isset", "empty" and "is_null" will be quite helpful for everyone.
