The simplest example is this:

function __autload($name) {

require_once 'lib/'.$name.'.class.php';

}

$glab = new GraficLab();

It will include ‘lib/GraficLab.class.php’ file.

The thing is, each time you call class_exists() function, if the class does not exists, it calls __autload() function. If autloading handler is simple, ok, not problem, but if you want a complex autoload engine it will consume a lot of memory.

My purpose is to define a new function like this:

function gl_class_exists($class) {

return in_array($class, get_declared_classes());

}

From now, each time you want to check if a class is declared, use this function. Of  course, you will have to compare the autoloading method with this checking function; in my case is better to use this method.

Waiting your opinion!

Agafa aire que no és curt i ve sense comes amb sa idea de no perdre’t de vista i fer-te arribar a n’es final d’unes lletres esbojarrades que si més no esper que t’agradin i que de fet ja fan camí però no conten una gran història només et roben un microbocí des teu temps i et mantenen a s’expectativa de què acabaran dient. Idò! Ja ho han dit.

[Castellano]

Toma aire que no es corto y viene sin comas con la idea de no perderte de vista y hacerte llegar al final de unas letras alocadas que al menos espero que te gusten y que de hecho ya hacen camino pero no cuentan una gran historia sólo te roban un microtrocito0 de tu tiempo y te mantienen a la expectativa para saber qué acabarán diciendo. Idò! Ya lo han dicho.

[Autotranslate: English]

Take a breath that is short and has no commas with the idea of ​​not losing sight of you and make you reach the end of a crazy letters that at least I hope that you enjoy and which already make their way but do not have a great story just want to stole you a micropiece of your time and keep you on the lookout to know what will end up saying. Ido! Have already said.

What is the gap? This way you will be able to choose which part of image you want to see and round.

Take a look on next code.

HTML, an image of 300×300 pixels:
<div>
<img src="http://www.jordisalord.com/wp-content/uploads/2012/02/qr-jordisalord-300x300.png" alt="Jordi Salord @ Blog" />
</div>

CSS:
<style>
div.img-round {
overflow: hidden;
border-radius: 5px;
box-shadow:-1px 1px 2px #000;
height:280px;
width:280px;
}
div.img-round img {
margin-top:-10px;
margin-left:-10px;
}
</style>

The original image:

The result:

That’s all folks!

What do you think about this technique? Is there any other way to do it?

Enjoy this tip, I’ve recently used this technique to round non-editable images.

Snow remembered me a thing: I really like QR codes.

QR codes can be useful for a lot of things: promoting your URL/Text/Images using a single image, posted or printed anywhere. Ok, it is a little bit geek, but there is no problem with that, isn’t it?

If you want to start using QR Codes for your brand, check this link: http://qrcode.kaywa.com/

[UPDATE]: Thanks to Aigu, I discover another generator that let’s your colorize it!

Here comes a QR Code with a link to my blog:

And another one with full info:

Try this with your website, brand or anything you want to easily promote.

Enjoy!

You have to create httpd.conf files inside these directories:

1. Domains
1. /var/www/vhosts/domain.com/conf/httpd.conf
2. Subdomains
1. /var/www/vhosts/domain.com/subdomains/subdomain.com/conf/httpd.conf

Then, once you have finished with configuration files, you must say Plesk to reload these configurations:

1. Per domain
1. # /usr/local/psa/admin/sbin/websrvmng -u --vhost-name=domain.com
2. Global
1. # /usr/local/psa/admin/sbin/websrvmng -a

It is really useful to add permissions, rewrites, svn, or anything you want.

Y añadir estas tres líneas de código:
global $query_string;
$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
query_posts($query_string . '&order=DESC&orderby=modified&paged='.$paged);

En este ejemplo s’está ordenando por fecha de modificación de forma descendiente, en lugar de hacerlo por fecha de publicación.

Se puede aplicar a cualquier zona del blog modificando otros archivos, como por ejemplo category.php.
