Remove HTML Tags Selectively in PHP
Question: How can I selectively remove all HTML tags from a string in PHP, except for a specified list of allowed tags?
Answer: To remove all HTML tags while preserving a specific set of allowed tags, utilize PHP's strip_tags function. The strip_tags function allows you to specify a string containing the tags you want to retain.

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.
