php regex: removing more than double space

Question

$tags = preg_replace(\'/\\s\\s+/\',\' \', $tags);

that will remove more than just one space ?

i need to remove anything more than double space.

Answer 1

I'm taking "more than double space" to mean 3 or more spaces:

$tags = preg_replace('/\s{3,}/',' ', $tags);

This will replace 3 or more contiguous occurrences of any whitespace character with a single space.
