In this example creating new variable string that will echo to particular string for example ‘This is an example string.’. Now we will doing few things along the tutorials. Now creating new variable which uses function and apply this function to this particular string. Now let see str_word_count this uses for count certain amount of words may be through user input and through database uses etc etc.. creating new variable $string_word_count and this will equal to function name which is str_word_count() this function take three arguments in total here i want only one argument required the one which is required is the actual string itself. So, I am just taking reference variable $string and echo out the result. And you can see result is 5 because in string we have 5 words. Full-stop does not count because it does not include in our word count.
