Answer 1

if you want to remove excess of only-spaces (not tabs, new-lines, etc) you could use HEX code to be more specific:

    $text = preg_replace('/\x20+/', ' ', $text);

Answer 2

http://www.php.net/manual/en/regexp.reference.escape.php defines \h any horizontal whitespace character (since PHP 5.2.4) so probably you are looking for

$foo = preg_replace( '/\h+/', ' ', $foo );
