Today my friend Sakib was looking for a Currency Exchange API to implement it on one of his projects. So, I decided to write this small PHP code snippet for him. I hope this will help him and also other developers. Because, XML-RPC section of the PHP Manual is still incomplete .

<?php

/*
* Reference :: http://foxrate.org/
*
* For $from and $to :: http://www.oanda.com/site/help/iso_code.shtml
*/

function getExchangeRate($from = 'USD', $to = 'BDT', $ammount = 1.0) {

    $ammount = doubleval($ammount);
    $request = xmlrpc_encode_request("foxrate.currencyConvert", array($from, $to, $ammount));

    $stream = stream_context_create(array('http' => array(
        'method' => "POST",
        'header' => "Content-Type: text/xml\r\nUser-Agent: xmlrpclib.py/1.0  1 (by www.pythonware.com)\r\nHost: foxrate.org\r\n",
        'content' => $request
    )));

    $endpoint = "http://foxrate.org/rpc/";
    $file = file_get_contents($endpoint, false, $stream);
    $response = xmlrpc_decode($file);

    if (is_array($response) && xmlrpc_is_fault($response)) :
        return 'error';
    else :
        return $response;
    endif;
}

print_r(getExchangeRate());

?>

Did you ever think of utilizing any site favicon? Probably not! But, I’ve been always thinking of it. Actually the space for the Bookmark Toolbar is never been enough for me, even in wide screen . So, I decided to remove labels from my toolbar bookmarks. And now its look like -

You can see, here my browser is Google Chrome. But, it is not necessary, you can also do it in Firefox.

Few days back I saw a really nice post of Nadim Jahangir about breaking captcha [Breaking CAPTCHA: Getting Naughty With Computer Vision Based Human Interaction Simulator Bot]. After, reading his post, I’d decided to create something similar with PHP. And I’ve already done it. I also use somewhereindhaka.net captcha for my experiment but didn’t create any bot to post in their site .

Steps are very simple -

1. Create horizontal & vertical histogram of captcha using PHP GD.
2. Recognize each character by comparing values from histogram.
3. I didn’t use any Template Recognition Algorithm. Rather, I use simple Edit Distance Algorithm (Levenshtein Distance). And it works
