[phpclass] dinamicParams – Calling function with named params

Gabi Solomon — Sun, 23 Nov 2008 15:17:49 +0000

A lot of time while developing a function or a method of a class you need to specify 1, 2 or 3 parameters as inputs for that function or method. But usually as you develop further you might end-up in the situation where you would want to add a new parameter to your function.

And so you might have coded a function that has 5 or more parameters, and although it works fine, eventually you will want to call that function and leave the first 4 parameters with the default value and only change the last one. I ended up here a lot of times, and normally in php there is nothing you can do.

A workaround would be to specify the params as a single array variable, but that is just making you write more code and it looks really bad ( at least in my opinion).

Well today i found a new method of doing this in php5 with the help of the Reflection API that is offer in php5. I will not get into to much details about what it does, you can read that in the documentation, basicly it provides a way to reverse-engineer classes, interfaces, functions and methods.

So i wrote a simple class that is going to solve that problem.

With the help of the Reflection API from php5 the class will allow you to call function and methods by providing the parameters as an array specifying names and values even if the original function or methods receives them in the normal fashion.

But enough talk, heres the example.

PLAIN TEXT

PHP:

require('dinamicParams.class.php');
class news {
function fetch ( $id, $page = 0, $items_pp = 10, $order_by = 'date', $method = 'desc') {
echo "
id: $id,
page: $page,
items_pp: $items_pp,
order_by: $order_by,
method: $method
";
}
}
$news = new news();
$dinamicParams = new dinamicParams();
$dinamicParams->call(array($news, 'fetch'), array('order_by' => 'name'));

This will output :

id: , page: 0, items_pp: 10, order_by: name, method: desc

This class is based on this implementation of the reflection API.

Want to build an application to update all major social services ?

As social networks seem to get bigger and bigger and new ways of online communication spring up, people get more and more caught up into updating their accounts on various networks.

So wheres there's a need there's an application .

As i was talking a few days ago a new service has been borne a few months ago called ping.fm that allows users to update their services all from one place. Well today i stumble upon a class on phpclasses.org called Ping.FM Wrapper that can be used to update multiple social networks using the Ping.FM API.

It accesses the Ping.FM Web services API server and can perform several operations to update social networks of a given user. It can for instance post messages or the user status, retrieve received messages, etc..

I guess this will make the life of developers required to do an application that will update social networks a whole lot easyer.

Cheers

Google Translate Tool Class v0.9

As almost all of my classes i have developed this class for a project requirement, and i decided to make it public on phpclasses.com that is available for download at this link.

This is quite a simple class can translate text, and webpages using Google translate services.

The class usses curl to make a tranlation request to the Google translate Web page and asking for the translation of the given text or URL from the selected from and to languages. The result is parsed to obtain the translation and returned by the class.

The translation class supports all the languages currently available at google including:
English, German, Spanish, French, Italian, Portuguese, Arabic, Chinese and Russian.
