How Can I Safely Remove HTML Tag Attributes Using PHP?

Safely Removing HTML Tag Attributes

When working with HTML code, there may be instances where you need to remove all attributes from tags to achieve a cleaner or more streamlined output. Here's how to achieve this using PHP's regular expression capabilities:

$text = '<p>

This powerful regular expression matches:

• The start of a tag with an alphanumeric tag name (<([a-z][a-z0-9]*))
• Any non-angle bracket characters following the tag name ([^>]*?)
• An optional closing slash for self-closing tags ((/?))
• The closing angle bracket marking the end of the tag (>)

The replacement text, <$1$2>, preserves the tag name and closing slash (if any) while removing all attributes.

Please Note:

This solution is not foolproof and may fail in certain cases, such as tags with empty attributes. For more robust attribute removal, consider using a dedicated PHP library like Zend_Filter_StripTags.
