Kevin Schroeder has some of his own thoughts on the recent results of the TIOBE index ranking the popularity of programming languages. PHP has slopped down two spots, replaced by Python and C++. He looks at the data TIOBE has to back it up and can't seem to find a reason why.

I decided to take a look and see what was going on behind the scenes by reading on the index definition to see if I could understand what happened. After reading through the definition I still don't know what happened, or even why it happened.

He goes through how the index data is created - search results from the top 6 hits in Alexa for each language result - and how he, basically, found nothing out of the ordinary. He points out that, because of inconsistencies like this, the TIOBE index shouldn't be regarded as much more than a loose guide. Since it's based on hard-coded search strings, it'll never be a true judge of "popularity" overall.

On the IBuildings bog today Ivo Jansch looks at a new step in PHP's evolution - its jump up into the top three on the TIOBE programming index (language popularity):

In their latest analysis PHP has entered the top 3 of most popular programming languages, and that is something that both makes us proud and provides further proof that PHP is still growing and here to stay. [...] What makes PHP's number 3 position remarkable is that the numbers 1 and 2 are very much general purpose languages. Java and C are pretty much used from anywhere from low level processes to desktop applications.

Some of the other languages in their top ten (according to their indexing tools) include Perl, Python, Ruby and Javascript.

According to the latest results for the TIOBE community index, PHP has made it into the top three in the monthly-updated list of programming language popularity.

PHP pushed ahead of now number four on the list, C++, with an almost one percent gain jumping up from number five on the previous month's list. The post includes graphs showing the trends and a link to the definition of the reports.

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.

As reported by the International PHP Magazine website, the results of the latest TIOBE Programming Community Index are in for the month and PHP is on the rise.

PHP has moved back up to take its spot back at #4 with (Visual) Basic falling back down to #5. As the trends graph shows, PHP had a sharp spike back up to overtake VB starting with the new year. If it continues the climb, it could be back up to levels it was during the middle of last year.

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.

According to the latest stats from the TIOBE Programming Community Index, PHP has dropped down a spot from its previous standing last month down to the number five slot for November, being bumped down by (Visual) Basic.

As the long term trends graph shows, though, PHP and Basic are neck and neck, with one only gaining slightly over the other. As the International PHP Magazine site notes:

As the graph on TIOBE's web site indicates, PHP has been charting an uneven course, facing ups and just as many downs. However, PHP's position as of Feb 2006 is significantly higher than that of 2005.

You can get all of the stats and graphs for this latest month of results from the TIOBE site.

As mentioned by the Zend Developer Zone, PHP is still holding strong in the TIOBE Programming Community index n terms of how popular the language is. PHP comes in, once again, at number four on the list, bested by (in descending order) Java, C, and C++.

Most of the top languages on the index are staying around the same spot, but two languages - Visual Basic and Python - are nipping at the top four's heels. Things are getting pretty neck and neck for three languages - PHP, Basic, and C++. Their stats have been fluctuating just around each other, but not changing enough to make a difference in the listings.

You can check out the full listing on the TIOBE Software website (including a graph of each language in relation to the others).

As mentioned in this new article on the International PHP Magazine's website today, PHP has come in fourth (once again) in the TIOBE Programming Community index's rankings.

PHP stands at fourth place in the October 2006 edition of the TIOBE Programming Community index. Its position has jumped a notch since last month, while Java continues to hold the top spot.

In long-term trends, PHP shows a significant jump from October 2001 to February 2002. As the graph on TIOBE's web site indicates, PHP has been charting an uneven course, facing ups and just as many downs. However, PHP's position as of Feb 2006 is significantly higher than that of 2005.

You can check out either their post or the actual index to get more information.

Back in 2004, PHP was named number one language of 2004. Since then, it's hovered in the top ten, maintaining its popularity and ranking, including a move up from 5th place to 4th (as mentioned on the Zend Developer Zone).

The TIOBE Programming Community Index has been updated for April 2006 showing their view on the status of programming languages in the development community. PHP moves up a spot from 5th to 4th. The long-in-the-tooth C fades back a bit relinquishing 1st place to Java, while C++ gains on its brethren with PHP biting on its heels (a margin of 0.02 between their percentages). PHP has a higher climb rate so expect another big move in the coming year.

For those that are wondering "why should I care?" about this random index? The post mentions how they come up with their numbers. It's mainly a popularity contest, but it's useful for seeing which way the public sways. The post also mentions thatm while it's one way to check the popularity, slightly altering the search parameters can give dramatically different results.
