Posted 2021-05-15

function cleanHTML($html) {
/// <summary>
/// Removes all FONT and SPAN tags, and all Class and Style attributes.
/// Designed to get rid of non-standard Microsoft Word HTML tags.
/// </summary>
// start by completely removing all unwanted tags

$html = ereg_replace("<(/)?(font|span|del|ins)[^>]*>","",$html);

// then run another pass over the html (twice), removing unwanted attributes

$html = ereg_replace("<([^>]*)(class|lang|style|size|face)=(\"[^\"]*\"|'[^']*'|[^>]+)([^>]*)>","<\\1>",$html);
$html = ereg_replace("<([^>]*)(class|lang|style|size|face)=(\"[^\"]*\"|'[^']*'|[^>]+)([^>]*)>","<\\1>",$html);

return $html
}
