Escape special chars in PHP

Question

How can I escape 'special chars' in PHP, regardless of in which enc-type they are? Like so:

INPUT: ë, ë

OUTPUT: e, e

I hope someone can help. Thanks in advance!

You don’t want _escaping_ here in the first place, according to the examples you have given – what you have described, is _substitution_ of characters by _other_ characters. — 04FS, Jan 20 '20 at 15:06
Have you tried anything? Might be worth showing us what you've tried and what error you are getting — Mark Davies, Jan 20 '20 at 16:17

Try starting with this:

function replace_accents($str) {
   $str = htmlentities($str, ENT_COMPAT, "UTF-8");
   $str = preg_replace('/&([a-zA-Z])(uml|acute|grave|circ|tilde);/','$1',$str);
   return html_entity_decode($str);
}

This function will convert all the accented chars into normal ones.

I've specified this regards 'accented chars' (not entity), it was just to start with a direction – Jazzpaths Jan 20 '20 at 14:55

... doesn't that basically make this question a duplicate? Should you not have just voted to close instead of answering? – CD001 Jan 20 '20 at 15:10
i think its not duplicate since this question is asking for the special character. and other is replacing accented characters. – KevDev Jan 20 '20 at 15:15
