Javascript array of bytes to binary string?

Question

This is my array of bytes: var $x = [108,181,183,176,140,239,53,105,104,47,47,21,147,67,96,87,175,35,67,97]

It has a binary PHP equivalent of gibberish: $x = "lµ·°Œï5ih//“C``W¯#Ca";

Now, what I can use so that javascript:btoa(SOME_ENCODING_FUNCTION($x)); perfectly matches <?php base64_encode($x); ?>?

Thank you!

Create a string using String.fromCharCode(), then pass it to one of the 100s of JS base64 implementations you can easily find on google. — DaveRandom

Yes, String.fromCharCode() is what I was looking for. Thanks. — Silviu-Marian

String.fromCharCode.apply(null, $x);

will return the string to use in btoa.

You can use base64_encode function but the javascript version of it

http://phpjs.org/functions/base64_encode:358

PHP JS is a good project that aims to port PHP functions to javascript, so if you ever need a javascript function that does exactly the same as a PHP function googling "phpjs _function_name_" will often give you what you are after :)

Apart from not answering my question, if you test it, it won't work on binary strings. Using btoa because it works on bin strings and my project doesn't need cross-browser.
