Answer 1

Using substr_count to Count the number of any substring occurrences. for finding number of words set $needle to ' '. int substr_count ( string $haystack , string $needle)

$text = 'This is a test';
echo substr_count($text, 'is'); // 2


echo substr_count($text, ' ');// return number of occurance of words
