PHP Currency Converter with Google Currency Converter API

Are you looking for a reliable PHP Currency Converter, here is Google give you a solution from their open Google Currency Converter API

How this API Works:

This PHP Currency Converter work with following URL call back.

Querying Converter API from PHP function as per following URL:

q=1USD=?INR

http://www.google.com/ig/calculator?q=1USD=?INR

Based on Google Currency Converter API, I build an PHP Function to get Currency values from the out put of http://www.google.com/ig/calculator?hl=en&q=1USD=?INR. as PHP Array

function google_currency_converter($amount,$to,$from="INR")
{
 $content = file_get_contents("http://www.google.com/ig/calculator?hl=en&q=$amount."."$from=?$to"); 
 // Remove Spaces on API Output
 $content = preg_replace('/[^A-Za-z0-9.]+/','',$content);
 // Match All Currency values 0-9 and .(decimal)
 preg_match_all('/([0-9.]+)/', $content, $m);
 
 // Convert values with 3 decimal points
 $currency[$from] = sprintf("%.3f",$m[0][0]);
 $currency[$to] = sprintf("%.3f",$m[0][1]);
 
 return $currency;
}


$c = google_currency_converter(2800,"USD");

echo "INR:".$c['INR'];
echo "<br />";
echo "USD:".$c['USD'];

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Text Area to Array</title>
</head>
<body>

<?php
// Check Form Submission
if(isset($_POST['submit']))
{
 // Capture cities text into variable
 $text = ucwords($_POST['cities']);
 // Replace entry new line with Comma(,)
 $cities = preg_replace("~\s*[\r\n]+~", ', ', $text);
 // Explode by Comma(,) and trim if any white spaces with array_map
 $cities = array_map('trim',explode(",",$cities));
 // final output as array
 echo "<pre>";
 print_r($cities);
 echo "</pre>";
}


?>

<form action="" method="post">
  <h2>Convert Text Area to Array</h2>
  <p>Enter each city every line<br />
    <textarea name="cities" cols="50" rows="10" id="keywords"></textarea>
