How to Remove Style Attributes from HTML Tags in PHP?

Scrubbing HTML Tags of Style Attributes

To remove style attributes from HTML tags in PHP, the preg_replace() function offers a powerful solution. The following code demonstrates how:

$output = preg_replace('/(<[^>]+)>

Breaking Down the Regex

The regex used here meticulously selects the targeted tags:

• <[^>] : Matches the starting HTML tag with any characters ([^>]) inside, excluding > characters.
• style=".*?": Captures the style="..." attribute and its contents. The .*? is a non-greedy quantifier that matches the shortest possible string that fulfills the pattern. The " ensures accurate matching of double quotes.

Replacement Logic

The $1 in the replacement string refers to the first captured group, which is the opening HTML tag without the style attribute. This effectively removes the style attribute from the tag while maintaining its content.

Caveats

This regex works well in most cases but may not handle extremely complex HTML structures. For comprehensive coverage, consider using a more robust HTML-parsing library.
