remove spaces - no line brakes

[pedroz]

I have this funtion below to:
1. remove multiple spaces from textarea
2. space at the end of the string...

function space($string) {	
$string = eregi_replace('^[[:space:]]+', '',preg_replace('/\s+/', ' ', $string));	
return $string; 
}

How can avoid removing the line breaks?

example:
Hi...
How are you?

with the function above it will result
Hi... How are you?

... removing me the line break and I only want to remove extra spaces

To remove space at the end of the string, use [man]rtrim/man
To remove consecutive whitespace but not newlines, match [\t ]+

function space($string) {
	return preg_replace('/[\t ]+/', ' ', rtrim($string));
}
