Planning on attending the International PHP Conference happening October 27th through 31st in Mainz, Germany? The ThinkPHP/Mayflower folks wanted you to know about their "Meet the Experts" event happening at their Coffee Lounge during the conference.

Coffee is the most important thing for developers. Yet, good coffee. At conferences it is almost vital to have a good coffee during the breaks and talk to experts. For this reason, MAYFLOWER will have a Coffee Lounge at the International PHP Conference in Mainz (Germany): Get coffee en masse for your business card.

Developers with lots of different specialties will be there on topics like web security, moving your applications to PHP5, getting the best performance out of your apps and the Zend Framework.

After singing the praises of DTrace for a while now, Johannes Schluter decided to show it off in a different way - introducing a collegue to it:

Yesterday, during a break at the Barcamp Munich, I gave Wolfram a short introduction on his Mac and decided to put some stuff here [in this post]. DTrace is a toolkit available on Solaris (Solaris 10 or OpenSolaris), recent MacOS versions and FreeBSD for mightier than tools like truss or strace but with way less impact. DTrace allows you to "hook" (called "probes") into the system and allows to do some analysis then.

He shows how to set up some of these "hooks" using D-script to wrap around a simple PHP script call. He alters the results to show things like the memory function its in, how much of the memory its using and a fu ......

Eran Galperin has a new post today that talks about profiling your database queries for optimum efficiency with the help of a component from the Zend Framework, the Zend_Db_Profiler.

Database performance is one of the major bottlenecks for most web applications. Most web developers are not database experts (and I'm no exception), there are however several basic methods to analyze and optimize database performance without resorting to expert consultants. [...] Since I'm dealing mostly (only?) with MySQL, this article covers it mainly (though it is probably relevant to a large degree for other engines).

Eran talks about first profiling your application and checking to see where the real problems might be. Something as simple as 2008-10-13 23:40:03 | 全文 | 评论(0)

So what do namespaces and playlists have to do with each other? Nothing of course. I am just mixing a short note that PHP 5.3 alpha3 is still delayed because of the lack of a decision on how namespaces are supposed to work, with one more genius idea I want to get published, before some idiot goes to patent town with it (though I heard that if someone is quick enough one can even get a legal patent of something that has been published shortly before a patent submission was made). So todays topic are playlists, or rather what I shall label "semi-manual continuous playlists".

I usually listen to my music in shuffle mode. However I also tend to skip songs a lot depending on my mood. Since I listen to music all day, I go through quite a number of songs in a day. Also I do own quite a ton of songs, a fair number of songs end up forgotten, but none the less still liked. I use iTunes (not because I like it, but its just so happily integra ......

PHPFreaks.com has posted part one of a series of tutorials covering some of the basics of one of the more powerful features in any language - regular expression support.

Regular expressions (which will now be referred to as "regexes") are basically pattern matching inside of text. They use special syntax and concepts in order to obtain information from a string. Many programming languages have some sort of support for regexes, because of the sheer usefulness of them. Not only can patterns be used to validate that a certain pattern exists in a string, but they can also be used to physically extract matched portions and make them usable in your PHP code.

They look at some of the basics - example structure, metacharacters, greediness as well as include a brief comparison of PCRE versus POSIX versions. The tutorial is peppered with plenty of example expressions t ......

On the NETTUTS website today there's a new tutorial about mashups - specifically showing how to create a sample one by combining three services: Google Maps, the IPloc service and the Beer Mapping Project.

This tutorial will show you how to create a mashup of three different APIs including integration with Google Maps. This idea came about when I was searching through ProgrammableWeb's API directory for a couple APIs that complimented each other enough that I could use one to provide the other with data. What I came up with will be known as the "Beer Mashup".

They include links to scripts to interface easily with the APIs and the sample code you'll need to query against them. They wrap it up with the HTML for the output page (a map showing "beer hot s ......

In a recent post to his blog Daniel Cousineau shows a method for correctly outputting CSV data in push down to the client browser as a method of export.

Nearly every application you could write in for the business sphere in PHP probably requires some sort of data export, most likely in the CSV format. The easiest way to provide a downloadable file is by altering the headers and echo'ing the file content.

His method sets the headers for the CSV file type then pushes the content out (contained in an array) via the fputcsv function. He wraps it all in a function near the end for simple cut and paste.
