Every now and then I want to profile a given part of PHP code. For example I want to quickly check wether my current changeset to GeSHi works faster or is horribly slower. For a big change I’ll stick to Xdebug and KCachegrind. But for a quick overview? Overkill in my eyes.
Say hello to profile.class.php, a simple timer class for PHP5 which you can use to get an overview about where how much time is spent. This is in no way a scientific method nor should you take the results of a single run as a basis for you decisions.
I’ve set an emphasize on an easy API so you don’t have to pollute your code with arbitrary hoops and whistles.
UPDATE: You can find the current updated source in the SVN repo of GeSHi.
» Opera 9.50 beta
Tue, 09/04/2007 - 15:43
Opera released their first 9.5 Alpha today, nicknamed Kestrel. Usually I don’t use Opera, I use Firefox for webdevelopment with Firebug and similar tools but it’s pretty slow even on my fast new machine. For my everyday browsing I use Konqueror for it’s neat desktop integration (read ASpell, KWallet, Kio, Filebrowser etc.). And compared to Firefox Konqueror is fast.
But Opera… Well I knew it was fast but in their release note they mentioned even more speed improvements, also for ECMA Script (JavaScript). So I thought, lets give it a try and I have to say I’m pretty much flabbergasted. It feals like it’s more than double as fast as Konqueror! I really might start to use Opera more frequently now… Let’s see what else they got except speed!
Also very interesting is this part of the release note:
Platform integration
We worked to make Kestrel feel even more integrated with your platform. Mac users can expect a nice new visual look and feel, while Opera for Linux will add a QT4 build, so you can easily adjust your skin to match the desktop. 64-bit Linux/FreeBSD packages will also be available.
Neat! I’m really looking foreward to this since I prefer programs which adapt to the widget styles I use and see in other (KDE/Qt) programs.
Downside
Even in my first few minutes of usage I encountered a few problems, most notably some layout quirks with form elements which resolve after a refresh of the page.
