Almost. Change it to: `preg_replace('/\s+/', '', $str);` (PHP does not have a `preg_replace_all()` function. And `\s` need not be in a character class.) – Amal Murali Apr 20 '14 at 15:01
Also the space is actually `[ ]`, you've answered for whitespace (which probably OP has been looking for), perhaps with UTF-8 encoded input? – hakre Apr 20 '14 at 15:02
In that case, the OP might want to use `\p{Z}` or `\p{Zs}`. – Amal Murali Apr 20 '14 at 15:07
It will not be possible to do it just with Regex and without using php? – amorino Apr 21 '14 at 01:10
you need some language anyway, Regex just a feature of language – Alex Apr 21 '14 at 06:05

<?php
$string = "Hello Word";
$string = preg_replace('/ /', '', $string);
echo $string;
//HelloWord
?>
