Update to "Please Don't Grab!"

After someone challenged me to write some type of program/script to find the frequency of the word grab occurring in a webpage I have an update for you.

The following two lines get the job done: 

$str = file_get_contents('URL'); //gets the contents of the webpage

print_r(array_count_values(str_word_count(strip_tags(strtolower($str)), 1))); //prints a list of all words found

The second line:

•  converts all words to lower case using strtolower
•  then it uses strip_tags to remove the html tags
• str_word_count returns information about words used in a string
• and array_count_values counts the values of the array

I copied and pasted a few URLs from the Pioneer Woman's website and ran the script to produce the following:
