The latest from the MySQL community

I was writing about PHP.next before, many things improved there meanwhile. Most notably we have a committed version number: The next PHP release will be called PHP 5.4. The topic I want to talk about today is "Improved application portability" which covers multiple small changes which aim at making it simpler for developers to write applications working on any PHP setup.

Separating <?= from short_open_tags

PHP knows quite a few ways to separate PHP code from surrounding text (usually HTML), most applications use <?php as that works on every system. There is a short form of this, <?, which can be disabled using php.ini's short_open_tags setting. Being able to disable this is important when embedding PHP code into XML documents containing XML processing instructions. Now we also have …

This year I'll attend OSCON for the first time. I'll give two talks:

• PHP and MySQL - Recent Developments
  PHP’s MySQL support recently received many changes under the hood. PHP 5.3 introduced mysqlnd – the MySQL native driver which is a replacement for libmysql deeply bound into PHP. In this presentation you will learn what the PHP and MySQL development teams were up to. After starting with an introduction of the PHP-stack, demystifying things like mysqli, mysqlnd or PDO, this presentation will show you how to build mysqlnd plugins as PHP C extension and hooking into mysqlnd from PHP userland. It will also discuss existing plugins like a client side query cache or a module for doing read-write-splitting, both working transparently, without changes to your application.

This week I've been using phpMyAdmin for what feels like the first time in years. I'm happier at the command line, but needed some graphical representation of information and easy ways to export example queries for the book I'm working on. I noticed that phpMyAdmin now has a Designer tab, which shows relationships between tables and allows you to define them.

If your table types don't support foreign keys, you can still draw links in here, and phpMyAdmin will show the id fields as links to the data they represent, which is quite a nice touch (MyISAM doesn't support foreign keys). If your database does support foreign keys, then I found this post which explained that you must have an index on the column that will …

I have been writing a bit about Gearman lately, including installing it for PHP and Ubuntu, actually using it from PHP and also how I use persistent storage with Gearman. I'm moving on to look at adding jobs of different priorities.

I use Gearman entirely as a point to introduce asynchronous-ness in my application. There is a complicated and image-heavy PDF to generate and this happens on an automated schedule. To do this, I use the GearmanClient::doBackground method. This inserts a priority 1 job into my queue. …

Lighttpd is a secure, fast, standards-compliant web server designed for speed-critical environments. This tutorial shows how you can install Lighttpd on an Ubuntu 11.04 server with PHP5 support (through FastCGI) and MySQL support.

I have been asked if there is a way to insert data into two MyISAM tables that connected by a one-to-one relationship in one MySQL query. For example: mysql> CREATE TABLE `user` ( `id` int(10) unsigned NOT NULL auto_increment, `name` varchar(255) NOT NULL default '', PRIMARY KEY (`id`) ) ENGINE=MyISAM AUTO_INCREMENT=5 DEFAULT CHARSET=latin1   mysql> […]
