As mentioned by the International PHP Magazine site, the latest results for the TIOBE Programming Community Index poll are in for January and it looks like PHP has lost some ground.

PHP, previously in the number four slot, has been superseded by Visual Basic by a decent margin (a difference of 1.18%). This shows as a drop in popularity (as measured by the survey) to be trending back down to where it was around the middle of 2005. It still remains in the top five, though, in a close race with Visual Basic and C++ for those three positions.

The full language list and graph showing the trends back to 2002 can be found on the TIOBE website.
