You can use the built in PHP function str_word_count. Use it like this:

$str = "This is my simple string.";
echo str_word_count($str);

This will output 5.

If you plan on using special characters in any of your words, you can supply any extra characters as the third parameter.

$str = "This weather is like el ninã.";
echo str_word_count($str, 0, 'àáã');

This will output 6.
