be ware that php urlencode is not compatible with javascript so u should use rawUrlEncode instead – Amir Surnay Oct 28 '13 at 13:42
Working for me (((PHP))) $msg = array(); $msg['adds'] = rawUrlEncode($complexAddsWithHTMLMarkup); echo json_encode($msg); ......(((jQuery ajax dataType json))) decodeURIComponent(msg.adds); – Coisox Aug 01 '14 at 11:41

Unfortunately, this answer is wrong for some characters. In php `rawurlencode(")") == "%29"` while in javascript `encodeURIComponent(")") == ")"`. – Régis B. Mar 20 '17 at 18:39

@RégisB. To comply to RFC 3986 there is a fix on [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/encodeURIComponent). To the bottom there is a function called `fixedEncodeURIComponent` – Michel Sep 29 '18 at 07:12

Try using rawurlencode instead - urlencode does some things differently for "historical" reasons.

See http://us.php.net/manual/en/function.urlencode.php for more information.

Parenthesis are exceptions to all of what is said in this post.

geek mode on :

false

PHP rawUrlEncode() !== JavaScript encodeURIComponent()

but true

PHP rawUrlEncode() == JavaScript encodeURIComponent()

In other words, there are many special characters that aren't treated as safe in rawurlencode when they are in encodeURIComponent.

Try this:

return decodeURIComponent((str + '').replace(/\+/g, '%20'));

I think it should be `replace(/\+/g, ' '))` – gregmatys Sep 27 '13 at 12:46

PHP rawUrlEncode with JS unescape (deprecated but working)

For me decodeURIComponent throw errors sometimes.
