How to Efficiently Strip Attributes from HTML Tags Using PHP?

Strip Attributes from HTML Tags

Many web applications require the removal of attributes from HTML tags for performance or security reasons. Consider the following HTML code:

<p></p>

To strip all attributes from this code, ensuring it resembles the following:

<p>
  <strong>hello</strong>
</p>

Utilize the following PHP code:

$text = '<p></p>

The regular expression employed in this code performs the following tasks:

• Captures the tag name in capture group $1.
• Captures the closing slash "/" in capture group $2, if present.
• Removes any text or attributes that appear between the tag name and the closing tag character.

By replacing the original text with the stripped-down version, you successfully eliminate all attributes from the HTML tags.

However, it's essential to note that this approach may not handle all possible HTML inputs perfectly. Therefore, it's advisable to consider using more comprehensive filtering mechanisms, such as Zend_Filter_StripTags, for more robust attribute removal.
