PHP removes the unformatted function directly pasted from word _ PHP Tutorial

PHP removes the unformatted functions directly pasted from word. There are two general processing methods: 1. directly remove them through the JS editor. 2. after the application is submitted to the background, remove the invalid tag using the program. Next I will share a PHP-based processing method. There are two general processing methods: 1. directly remove them through the JS editor. 2. after the application is submitted to the background, remove the invalid tag using the program. Next I will share a PHP processing method with a success rate of not 100%. This program is also seen on the PHP official website and pasted by the way.

The code is as follows:

Function ClearHtml ($ content, $ allowtags = ''){

Mb_regex_encoding ('utf-8 ');
// Replace MS special characters first
$ Search = array ('/U','/U', '/', '/"/U ', '/-/u ');
$ Replace = array ('\'','\'','"','"','-');
$ Content = preg_replace ($ search, $ replace, $ content );
// Make sure _ all _ html entities are converted to the plain ascii equivalents-it appears
// In some MS headers, some html entities are encoded and some aren't
$ Content = html_entity_decode ($ content, ENT_QUOTES, 'utf-8 ');
// Try to strip out any C style comments first, since these, embedded in html comments, seem
// Prevent strip_tags from removing html comments (MS Word introduced combination)
If (mb_stripos ($ content ,'/*')! = FALSE ){
$ Content = mb_eregi_replace ('#/\*.*? \ */# S', '', $ content, 'M ');
}
// Introduce a space into any arithmetic expressions that cocould be caught by strip_tags so that they won't be
// '<1' becomes' <1' (note: somewhat application specific)
$ Content = preg_replace (array ('/<([0-9] +)/'), array ('<$1'), $ content );

$ Content = strip_tags ($ content, $ allowtags );
// Eliminate extraneous whitespace from start and end of line, or anywhere there are two or more spaces, convert it to one
$ Content = preg_replace (array ('/^ \ s +/', '/\ s + $ /', '/\ s +/u'), array ('','', ''), $ content );
// Strip out inline css and simplify style tags
$ Search = array ('# <(strong | B) [^>] *> (.*?) # Isu', '# <(em | I) [^>] *> (.*?) # Isu ','# ] *> (.*?)# Isu ');
$ Replace = array (' $2',' $2',' $1');
$ Content = preg_replace ($ search, $ replace, $ content );

// On some of? Newer MS Word exports, where you get conditionals of the form 'If gte mso 9', etc., it appears
// That whatever is in one of the html comments prevents strip_tags from eradicating the html comment that contains
// Some MS Style Definitions-this last bit gets rid of any leftover comments */
$ Num_matches = preg_match_all ("/\
