PHP is the most popular web application programming language, according to Imperva. The language, PHP, handles certain kinds of variables in its code, a report says. The report was critical of the way the application programming programming language defines by default certain “super global” variables and allows external programs, such as cookies, to manipulate them. PHP has been in the sights of hackers for years, with 2,100 flaws listed in the ISS database of vulnerabilities to tempt net baddies. “Technically, PHP isn’t broken,” NSS Research Director Chris Morales said in an interview.”]
