Replacing Perl Scripts with PHP Scripts

Replacing Perl Scripts with PHP Scripts 11/26/2002 05:12 AM
With the introduction of version 4.2, PHP has started supporting a new SAPI (Server Application Programming Interface) called CLI (Command Line Interface). This facility was introduced to help developers create small shell applications (scripts) with PHP. So, now you can kiss Perl goodbye forever. -- Jayesh Jain

Hear hear. Thanks to my influence, other developers at Natsoft are using PHP for their batch scripts too. Hmm maybe it is because they report to me...

iTunes hacker ranks music and auto-pays

iTunes hacker ranks music and auto-pays
musicians with perl scripts 04/19/2005 03:38 AM
Cory Doctorow: Merlin sez, "Glenn McDonald has concocted a wonderfully byzantine bit of iTunes scripting that rates his music tracks automatically based on a number of factors. Great stuff. Perhaps most interestingly, though, he uses some of the resulting data from his listening habits to determine any outstanding 'payments' that he owes to the artist, dutifully paid via an automated perl script."

For artists who accept electronic payment via Paypal or credit cards, the database records the relevant payment info. A separate nightly perl script issues electronic payments (via CapitolOne's excellent web-services "micropayment" (sic) interface) where possible (batched until the amount exceeds $1.75), and for artists without electronic payment info, totals the corresponding amounts and transfers the overall total to the money-market escrow account I have for this purpose. The escrow account isn't automated yet, but I usually kludge around this, when I get new payment info for an artist, by simply moving the money back out of escrow, resetting the amount paid/escrowed to $0, and rerunning the original script. At the end of each month I mail physical checks to artists for whom I have physical addresses but not electronic, and rebalance the escrow account accordingly. I don't currently have a way to split this compensation across the performer and the publisher for material where the two are different. The best I can do is include track info with all my payments and rely on the artist in turn to pay for material they acquired from elsewhere.

I did an interview last month with James Schellenberg from Strange Horizons, on the kind of music I listen to while writing, as part of a piece on SF writers' listening habits. I hand-rate all my music and use iTunes's last-played feature to put together a rolling playlist of high-ranked music I haven't heard in 30 days or more, so I get to hear all my fave music (at least) once a month.

FunkDaddy: "I wanted to look at the code of an AppleScript in the Scripts Menu. Normally, I would have to do this by navigating to the script in the Finder and opening it in Script Editor. But I took a wild guess and Option-clicked on the script in the menu, and it opened in Script Editor directly! This makes tweaking my frequently-used scripts really easy."

Going the whole hog: benchmarking MDB

Going the whole hog: benchmarking MDB 02/06/2003 11:53 AM
Well since I just benchmarked dbx, I decided to go the whole hog and benchmark MDB also. This gives us a good idea of the performance of all the modern database abstraction classes available for PHP:

        Average	 Overhead
MySQL	 1.14	  -
dbx      1.37     20% (index only)
ADODB	 1.45	  27%
dbx      1.53     34% (index/assoc/info)
PhpLib	 1.60	  40%
MDB      1.75	  54%
PEAR DB  2.87	 152% (fetchInto)
PEAR DB  3.15	 176% (fetchRow)
M'base	 2.52	 296% (numeric cols)
M'base	 4.77	 318% (assoc cols)

Benchmarking PHP with no BS

Benchmarking PHP with no BS 04/09/2004 03:58 PM
After I posted my XML benchmarks in February 2004, I was approached by Indu Britto to convert a discussion of the full benchmarks into an article for PHP Magazine. I kept on postponing him (correction, 2 Apr 2004: Indu is a her, apologies for the goof), but in a way, Prophet Mohammed helped me write the article. I'm not muslim, but the prophet's birthday is a public holiday in Malaysia. That gave me the breathing room to write the article.

I tried to make the article interesting by not focusing on the mechanics of the benchmark (yawn), but on useful results that everyone can use to improve their code. I was very pleased (and surprised - no one told me beforehand) to hear that the editors decided to feature it as the main article of the March 2004 issue.

Now that it has been published, i can announce that the source code of the benchmarking suite and results are available at http://ormestech.com/benchmark_suite/ . The results are static html pages to prevent enthusiatic testers from bringing our server to its knees. You should download the source code to try out all its functionality. The benchmarks are easily extensible also. You just need to add new benchmarking files and the benchmarking suite will auto-detect the files.

The nice thing about the benchmarks is that it measures relative performance between algorithms, so you can make meaningful conclusions across disparate hardware platforms. And if you need more clarification, you can read it (shameless plug) in PHP-Mag.

Benchmarking dbx, preliminary results

Benchmarking dbx, preliminary results 02/05/2003 11:18 AM
Yesterday, I benchmarked dbx, native MySQL and ADOdb. The results might be interesting to some of you:

                Average  Overhead
MySQL native	 1.14	  -
dbx              1.37     20% (flags=DBX_RESULT_INDEX)
ADOdb	         1.45	  27% (numeric indexes)
dbx              1.53     34% (default flags)

This reveals that dbx using default settings will provide no speedup over ADOdb because it also queries the field information and generates both associative and numeric indexes. The speedup of dbx over ADOdb is minimal when the dbx flags is set to DBX_RESULT_INDEX.

The benchmark algorithm used is the same one as that found at http://phplens.com/lens/adodb/ and if i have the time, i will upload the dbx benchmark source. Test system was a 800Mhz PIII running Win2000 with IIS and MySQL installed.

John's PHP Benchmarking Suite (ZIP)

My benchmarking suite. Apart from XML, it also benchmarks string handling, looping (foreach vs for), output buffering, etc. And it's easily extensible too.

I wrote it when i was thinking about writing a book on optimizing PHP, and realized i would need a benchmarking suite to test various performance hypotheses. Its not OOP, but i think it demonstrates how far you can make procedural programming extensible in PHP.

The benchmarking engine scans sub-directories, and each sub-directory is treated as a test suite. A .php file in a sub-directory is one test. Every .php file in a sub-directory can be run stand-alone, and when running stand-alone debugging output is generated so you can verify the correctness of the code you are measuring.

To install, just unpack in a web server directory, and open up index.php from your web browser.

Requires PHP 4.3 or later.

Sebastian is doing some neat work on testing performance. I found it hard to decipher the data, so I graphed it in Excel.

There seems to be some drop-off in performance in PHP 4.3.4. I guess the core developers are putting their energies into PHP 5.
