$str = "one    two              three";
$str = preg_replace('/ +/',' ',$str);

This replaces one or more spaces with a single space. It will also replace a single space with itself!! To improve it a bit:

$str = preg_replace('/ {2,}/',' ',$str);

which replaces a group of 2 or more consecutive spaces with single space.

I think `preg_replace('/s+/',' ',$str);` would be a little better. – Jesse Good Dec 20 '11 at 06:02

try this:

$str = preg_replace("/[ ]{2,}/", " ", $str);
