A nested query must have an alias, so I added 'X' as the alias in your code:
As regards your earlier question, in MySQL and other databases too, there is a difference between single quote (') and backquote (`). I think you meant to use the latter, which is what Ditto was getting at.

mixed str_word_count (string $string, [int $format], [string $charlist])
DESCRIPTION
Counts the number of words inside $string. If the optional $format is not specified, then the return value will be an integer representing
the number of words found. In the event the $format is specified, the return value will be an array, content of which is dependent on the
$format. The possible value for the $format and the resultant outputs are listed below.
For the purpose of this function, 'word' is defined as a locale dependent string containing alphabetic characters, which also may contain,
but not start with "'" and "-" characters.
PARAMETERS
o $string
- The string
o $format
- Specify the return value of this function. The current supported values are:
o 0 - returns the number of words found
o 1 - returns an array containing all the words found inside the $string
o 2 - returns an associative array, where the key is the numeric position of the word inside the $string and the value is the
actual word itself
o $charlist
- A list of additional characters which will be considered as 'word'
RETURN VALUES
Returns an array or an integer, depending on the $format chosen.
