As mentioned by the International PHP Magazine, PHP has held strong at its fourth place ranking on the TIOBE Programming Community Index for the month of May.

The TIOBE Programming Community index gives an indication of the popularity of programming languages. The index is updated once a month. The ratings are based on the world-wide availability of skilled engineers, courses and third party vendors. The popular search engines Google, MSN, and Yahoo! are used to calculate the ratings. Observe that the TIOBE index is not about the best programming language or the language in which most lines of code have been written.

PHP kept its ranking right alongside other popular languages like C++, Java and Perl to remain in the top five of the list. Their graph still shows a downward trend for the presence of PHP on the web, but it's the same trend that can be seen affecting several other languages as well.
