Too long URLs in Apache

It turned out that in current version of Apache you’re limited to 255 characters at most between each pair od slashes (after URL decoding is done). This short article discusses this issue and maybe useful to all developers, who are dealing with “beauty” (SEO-optimized) URLs, like for example URLs to blog posts containing entire title inside.

This is a rare situation (255 characters limit between slashes, not for the entire URL), but still worth exploring.

Is it possible to convert working pure PHP appication to Yii

I was once asked, if it would be possible to do step-by-step conversion of a large project written in pure PHP into Yii. In my opinion, it is possible, but absolutely not worth it.

Most professional frameworks are complete opposite to “pure PHP” code in actually all areas. Code is separated most times (i.e. into model, view and controller in MVC design pattern) and uses mostly framework classes or code. I would even say, that writing an application in some framework means using only 10-20% of pure PHP code and doing rest purely on framework classes, extensions, controllers etc.

In other words: porting a “pure PHP” application into framework code would mean writing that application from scratch. I’m not sure, if you would be able to reuse more than 5% of your original source code?

Using PHP and Oracle database

I was working on bigger project using PHP (Yii) and Oracle database (through PDO and Yii). This isn’t a very common combination and many developers thinks, that writing PHP application to use Oracle database is a pure madness, mostly due to many strange behaviors and nasty bugs, that are present in PDO driver for Oracle. I can actually confirm this. Following article contains links to my Yii forum discussions on various aspects of using Oracle with Yii and PHP. You may find it useful, if you’re struggling with any problem.

Modify CGridView look

The CGridView class in Yii is a state of art solution, that gives you out-of-the-box full model browsing features including filtering, pagination and sorting. The picture would be perfect, if not for default look of grid view, which is a little bit “nasty”! :> It is understandable, as Yii author focused himself on delivering perfectly working framework, that does not necessary have to be pretty in the same time.

However, basing on famous flexibility of all components in Yii, with a help of few simple steps, you can completely change the look & feel of your grid view.

Populate record

You can use CActiveRecord::populateRecord method in Yii to create new record basing on existing one. And, as this descriptions means, you must use it like that:

[code language=”php”]
$data = $this->getUser($id);
$model = new Users;
$model = $model->populateRecord($data, FALSE);
[/code]

instead of (last line):

[code language=”php”]
$model->populateRecord($data, FALSE);
[/code]

because populateRecord creates new model instead of modifying existing one!
