Wanted to understand What will be API

nani_nisha06 · 11-17-2012, 05:29 PM

Hi Friends,

I am back with another point of discussion.These time I wanted to know what is API really means in technical or practical terms? .....i know its theoretical definition is "Application programming interface". But, I wanted to see some good examples or theories how they really work. For instance i am new with PHP and if some one says API how should I understand & react to it as a PHP developer.

I wanted to clear up this doubt because where I working currently every one uses only API language ...and being technical & Service delivery manager I don't know how really it works... of course I also keep referring API language with out knowing any pinpoint of it coz my client dose the same even I need to, Funny rite...so, At this point I don't want to be a dumb crackling guy in front of them. on the same reason I have started learning PHP and now I want to deep down in to it step by step.

Any write ups or discussion?

I am really happy to discuss on this...

Regards,
Nani

Google is your friend.

But look at the following links:

http://en.wikipedia.org/wiki/Applica...ming_interface

http://www.quora.com/APIs/What-is-an...n-layman-terms

http://www.wisegeek.com/what-is-an-api.htm

http://www.computerworld.com/s/artic...ming_Interface

Anybody can build there own simple API's. For example:

PHP Code:


			
<?php

//http://jayctech.com/pics.php

if(isset($_GET['user_id']))
{
//Queries to get user name, picture from mysql database

echo "$picture_location";

}

At the page that requested the picture, have the following code.(I've made it very long with unnecessary code to make it easily understandable).

PHP Code:


			
<?php
$pic_location = file_get_contents('http://jayctech.com/pics.php?id=2');
?>

<html>
<body>
<img src="<?=$pic_location?>" />
</body>
</html>
