Remove all white space from a string

[Rulkster]

Is there an easy string function that will remove all white spaces from a string.
EX.

$mystring = "hello goodbye blue red yellow green";

i want the string to be:

hellogoodbyeblueredyellowgreen

Thanks.

Well, let's start with the obvious --

$mystring = str_replace(" ", "", $mystring);

Are we missing something? Do you want something different?

Man do I feel dumb. For I don't know how long, I've been using this:

$result = "";
for ($i = 0; $i < strlen($str); $i++) if ($str[$i] != " ") $result .= $str[$i];

That's a big Homer "d'oh" for me. Thanks.
