There are two kinds of general processing methods: 1. JS is removed directly from the editor. 2. After submitting to the backstage, the invalid label is removed directly from the program. Below I will share a way to deal with PHP, the success rate may not be 100%. This procedure is also on the PHP official website to see, by the way pasted over.
Copy CodeThe code is as follows:
function clearhtml ($content, $allowtags = ") {
Mb_regex_encoding (' UTF-8 ');
Replace MS special characters first
$search = Array ('/'/U ', '/'/U ', '/'/U ', '/'/U ', '/-/u ');
$replace = Array (' \ ', ' \ ', ' ' ', ' ' ', '-');
$content = Preg_replace ($search, $replace, $content);
Make sure _all_ HTML entities is converted to the plain ASCII equivalents-it appears
In some MS headers, some HTML entities is encoded and some aren ' t
$content = Html_entity_decode ($content, ent_quotes, ' UTF-8 ');
Try to strip out all C style comments first, since these, embedded in HTML comments, seem to
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 this could be caught by strip_tags so this they won ' t be
' <1 ' becomes ' < 1 ' (Note:somewhat application specific)
$content = preg_replace (Array ('/< ([0-9]+)/'), Array (' < $ '), $content);
$content = Strip_tags ($content, $allowtags);
Eliminate extraneous whitespace from start and end of line, or anywhere there is or more spaces, convert it to one
$content = preg_replace (Array ('/^\s\s+/', '/\s\s+$/', '/\s\s+/u '), Array (', ', '), $content);
Strip out inline CSS and simplify style tags
$search = Array (' #< (strong|b) [^>]*> (. *?) #isu ', ' #< (em|i) [^>]*> (. *?) #isu ', ' # ]*> (. *?)#isu ');
$replace = Array ('
$', '
$', '
$');
$content = Preg_replace ($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 was 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 ("/\
