Convert string in php

Question

I have one string:

"Hello\u00c2\u00a0World"

I would like convert in:

"Hello World"

I try :

str_replace("\u00c2\u00a0"," ","Hello\u00c2\u00a0World");

or

str_replace("\\u00c2\\u00a0"," ","Hello\u00c2\u00a0World");

but not work!

Where does that string come from? Is it possibly a JSON encoded string? I'm smelling some serious encoding conversion problem here. — deceze, Nov 12 '13 at 14:58
Remember that you have to assign that back to the string, i.e. `$string = str_replace(..);` - working: http://codepad.org/qcCtedUr — naththedeveloper, Nov 12 '13 at 14:59

Resolve!

str_replace(chr(194).chr(160)," ","Hello\u00c2\u00a0World");

If you would like to remove \u.... like patterns then you can use this for example:

$string = preg_replace('/(\\\u....)+/',' ',$input);

i don't want remove but replace! – Mauro Midolo Nov 12 '13 at 15:00
This replaces it to spaces. If you would like to unescape them, this link (mentioned by perdeu) can help: http://stackoverflow.com/questions/8180920/how-to-decode-something-beginning-with-u-with-php – Lajos Veres Nov 12 '13 at 15:02

You are most of the way there.

$stuff = "Hello\u00c2\u00a0World";
$newstuff = str_replace("\u00c2\u00a0"," ",$stuff);

you need to put the return from str_replace into a variable in order to do something with it later.

This should work

$str="Hello\u00c2\u00a0World";   
echo str_replace("\u00c2\u00a0"," ",$str);

You may try this, taken from this answer

function replaceUnicode($str) {
    return preg_replace_callback("/\\\\u00([0-9a-f]{2})/", function($m){ return chr(hexdec($m[1])); }, $str);
}
echo replaceUnicode("Hello\u00c2\u00a0World");
