OK, you could use several different ways (again, speed is not as
important as readability and maintainability).  Again, a regex is
overkill for something so simple.

So it looks like you're only concerned of the times when you have no
spaces in your string, but have one value.

First thing I would do is get rid of any leading and trailing white
space using trim:

$str1 = trim($str);

Then I would use the previous examples to extract the numbers and see
how many spaces (and numbers) you have.
