You can download simple_html to parse the html code.
Then traverse all the divs and
1. obtain the div id and check whether the div contains comment or share.
1. obtain the div class and check whether it contains comment or share.
If yes, delete the div and output the processed html.

Share) [^>] *> (. *) <\/div>/is ', '', $ htmls); // greedy match

If the regular expression does not work, you can use one character or one character to check the regular expression. Regular expressions are sometimes not omnipotent. they are only useful for regular strings.
