Pattern matching: <http://php.net/preg_match>

If the function returns 0 for the proper pattern, there either is no number 
or there is no number followed by space.

If it returns 1 then, there is a number followed by space.

For the first number, all preceding characters (in the line) must be non-
digits.  That can either be addressed with a negating *character class* (see 
the corresponding section in the PHP manual) or with negative *lookbehind* 
(see the section “Assertions”).
