Common gotcha, what you’re missing there is the apache developer libraries. What distro are you on? For example, on Ubuntu you can install those using “sudo apt-get install apache2-threaded-dev”

Installing APC isn’t as easy as it sounds….

checking whether the C compiler works… configure: error: cannot run C compiled programs.
If you meant to cross compile, use `–host’.
See `config.log’ for more details.
ERROR: `/root/tmp/pear/APC/configure –with-apxs’ failed

I’ve been toying with the idea of using a singleton for my database class… or one for read and another for right… or a singleton with somekind of factory init which passes back the db handle for read or write depending on an arg… Thoughts? I use a singleton for my error messages class, so the model/validate methods can write to it, the controller can check it, and the view can show the errors easily… It’s like globals through a back-door, but right now I’m saying global $DB_WRITE anyway…

Oh, and what’s the 2nd false argument to spl_autoload_register. It’s not documented? Namespace?

I was delighted to learn that SPL is compiled by default in PHP5 now. I hadn’t checked on that one in a long time…

Instead of include_once and require_once, do you recommend simply using include and require?

Also, with autoload (_autoload or spl method), that stuff is not loaded twice, because those are only called the first time the class file is needed, right?

Great slides. Wish I could have caught your presentation. Congrats, my young friend!
