How do you parse and process HTML/XML in PHP?
PHP offers a wide range of approaches for parsing and processing HTML or XML:
Native XML Extensions
- DOM (Document Object Model): Provides an object-oriented interface for manipulating XML documents, including parsing, modifying, and querying.
- XMLReader: An XML pull parser that operates as a cursor, traversing the document and stopping at each node.
- XML Parser: A SAX (Simple API for XML) style push parser that creates XML parsers and defines event handlers.
- SimpleXML: Converts XML to objects, enabling easy processing with property selectors and iterators.
3rd Party Libraries (libxml based)
- FluentDOM: A jQuery-like interface for the DOM, using XPath or CSS selectors.
- HtmlPageDom: Manipulate HTML documents using DOM, extending DomCrawler with methods for manipulating the DOM tree.
- phpQuery: A CSS3 selector-driven DOM API based on jQuery.
- laminas-dom: Provides tools for working with DOM documents and structures, including CSS selectors.
- fDOMDocument: Extends the standard DOM with exception handling and convenience methods.
- sabre/xml: A library for mapping XML to objects/arrays, providing fast and low-memory processing.
- FluidXML: A concise and fluent API for manipulating XML using XPath.
3rd-Party (not libxml-based)
- PHP Simple HTML DOM Parser: A fast and easy-to-use HTML parser, not recommended for performance reasons.
- PHP Html Parser: A CSS selector-based parser, not recommended due to slow performance.
HTML 5
- HTML5DomDocument: Extends the native DOMDocument library, fixing bugs and adding new features for HTML5.
- HTML5: A standards-compliant HTML5 parser and writer written entirely in PHP.
Regular Expressions
Regular expressions are not recommended for parsing HTML due to their brittleness. Custom parsers using regular expressions are time-consuming to write, and less reliable than existing libraries.

How do I destroy a session in PHP using session_destroy()?
Jun 20, 2025 am 01:06 AM
To completely destroy a session in PHP, you must first call session_start() to start the session, and then call session_destroy() to delete all session data. 1. First use session_start() to ensure that the session has started; 2. Then call session_destroy() to clear the session data; 3. Optional but recommended: manually unset$_SESSION array to clear global variables; 4. At the same time, delete session cookies to prevent the user from retaining the session state; 5. Finally, pay attention to redirecting the user after destruction, and avoid reusing the session variables immediately, otherwise the session needs to be restarted. Doing this will ensure that the user completely exits the system without leaving any residual information.
