I have created a static website. Each page was created by manually coding. Now when I checked out Bing crawlers report. They refused to index by saying that the length of the meta description is more than 160 characters. I am unable to (because pages are too much) modify each file to edit meta descriptions under the required limit. Is there any way to show only 160 characters to the crawler by any script? Or any other way so that Bing index my website.

Note that every page has a .php extension and the rest of everything in it is not linked to the database.
