And you could even remove the '+'.

Won't work either. :)
This should work fine:
if (preg_match('|\s+|i', $string) === 0)
{
echo '$string does not contain white spaces!';
}
elseif preg_match('/\s+/i', $string)
{
echo 'One or more white spaces found!';
}
else
{
echo 'An error has occurred!';
}
According to your needs, it could be simply shortened to the first if:
if (preg_match('/\s+/i', $string) === 0)
{
echo 'No white spaces';
}
Hope that works well.

Won't work either. The problem lies in using the === comparison
operator. preg_match() returns 0 if no match is found, and FALSE if an
error occurred. So using === will always echo 'No spaces' whether
there were spaces or not, provided that no error has occurred.
if (!preg_match('/\s+/i', $string))
{
echo 'No spaces';
}
should suffice.

How about:
if (preg_match('/\s/', $string) === false) {
echo 'No spaces!';
}
