The International PHP Magazine has posted results from their latest PHP community poll as voted on by visitors to their site. The question for this poll asked developers what they thought, of the choices on the list, was the most common mistake that PHP developers make.
Coming in at number one by an overwhelming lead was “Not escaping entities and SQL input” (a definite problem indeed) with the next highest option, “Not using a Framework” a full twenty percent lower. The next two options were closer (descending) - “Using old PHP versions” and “No or little use of Object Orientation”.
There’s a new poll this week for your consideration - this time asking which stage, of the five options, should come first in the development cycle of a typical content management system. Head on over and cast your vote today!

As mentioned over on the Zend Developer Zone, the IBM developerWorks website has posted a a new tutorial with a hand-holding guide to the creation of your own PEAR channels.
This tutorial discusses channels, introduces and explains the channel.xml file, and demonstrates how to build a channel for distributing packages. Channels are ordinarily used to expose PEAR packages through the Internet, but enterprises can uses channels to make distribution of enterprise-specific PHP code easy.
You’ll need to log in to the IBM developerWorks website to get to the good stuff (you do have a login, don’t you?), but once you do, you’ll find a guide that goes through:
- what PEAR is and what PEAR channels are
- channel management (including the channel.xml file)
- building the XML-RPC methods
- publishing the channel
- installing and upgrading a test package
- and some troubleshooting hints and further resources

On the Windows Skills blog, there’s a new post that talks about the use of a SQLite database (via PHP) to handle the assault that Digg.com can dish out to a popular webiste.
Physical memory was limited and Apache and MySQL soon started to fight for every remaining byte and eventually the page was unavailable.
After this experience I started to look for a alternative for the database storage and I found an interesting one: SQLite.
He mentions some of the features the database has including zero-configuration, a simple API, and the portability of having a single database in a single file. The next step was getting it to work with his Apache/PHP5 installation and to run some statistics on it. The results show SQLite pulling ahead of MySQL (INNODB) by a bit and MySQL (MYISAM) by a good bit.
