Use Google finance calculator to convert currency with php

gistfile1.php

<?php
function convertCurrency($amount, $from, $to){
	$data = file_get_contents("https://www.google.com/finance/converter?a=$amount&from=$from&to=$to");
	preg_match("/<span class=bld>(.*)<\/span>/",$data, $converted);
	$converted = preg_replace("/[^0-9.]/", "", $converted[1]);
	return number_format(round($converted, 3),2);
}

echo convertCurrency("10.00", "GBP", "USD");

@cameraki thanks for this. Is there a $amount variable that can be applied?

Okay, this works for me. Hope it helps:

function convertCurrency($from, $to, $amount){
$url = file_get_contents('https://free.currencyconverterapi.com/api/v5/convert?q=' . $from . '_' . $to . '&compact=ultra');
$json = json_decode($url, true);
$rate = implode(" ",$json);
$total = $rate * $amount;
$rounded = round($total); //optional, rounds to a whole number
return $total //or return $rounded if you kept the rounding bit from above
}

thank you all, it really helped me

Just change your currency as necessary:

<?php
        $from = "ZAR";
        $to = "USD";
        // create curl resource 
        $ch = curl_init(); 

        // set url 
        curl_setopt($ch, CURLOPT_URL, "https://free.currencyconverterapi.com/api/v5/convert?q={$from}_{$to}&compact=ultra"); 

        //return the transfer as a string 
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 

        // $output contains the output string 
        $output = curl_exec($ch);
        // close curl resource to free up system resources 
        curl_close($ch); 
		$data = explode(':', $output);
		$data = explode(" ", $data[1]);
		$amnt = round($data[0], 8);
		echo $amnt;
?>

Thanks guys for keeping this gist active :)

Thanks guys for the solutions.

Thank you for keeping this alive!

i created conversion using a standard Google search.
I know it isn't very clean but it works for me. Here is a link to function:
https://github.com/KhunHtetzNaing/google-currency-converter-api

how to replace it

	$get = file_get_contents("https://finance.google.com/bctzjpnsun/converter?a=$encode_amount&from=$from_Currency&to=$to_Currency");

This works for me

    import urllib2
    import json
    curr_from = "JPY"
    curr_to = "INR"
    curr_input = 1
    curr_pair = curr_from + "_" + curr_to
    api_url = "https://free.currencyconverterapi.com/api/v5/convert?q={0}&compact=ultra".format(curr_pair)
    jsonurl = urllib2.urlopen(api_url)
    rate_json = json.loads(jsonurl.read())
    rate = curr_input * float(rate_json[curr_pair])
    print rate

As google shut down converter link you just need to replace url given below

Just replace:
https://www.google.com/finance/converter?a=
https://finance.google.com/finance/converter?a=
https://finance.google.com/bctzjpnsun/converter?a=
http://free.currencyconverterapi.com/api/v3/convert?q=

with this URL:
https://www.xe.com/currencyconverter/convert/?Amount=

https://www.xe.com/currencyconverter/convert/?Amount=

Doesn't work anymore either

Thanks for referencing free.currencyconverterapi.com , please use the "v5" onwards API. And just to give a quick update, refresh values are now updated every 60 minutes.

Friends don't worry i made the converter working again use the following code
`<?php
function convertCurrency($amount, $from, $to){
$data = file_get_contents("https://www.xe.com/currencyconverter/convert/?Amount=$amount&From=$from&To=$to");
//var_dump($data);
$doc = new DOMDocument;
$doc->loadHTML($data);

$xpath = new DOMXPath($doc);
$node  = $xpath->query("//span[@class='uccResultAmount']")->item(0);
echo trim($node->nodeValue); //=> "$249.95"

}
echo convertCurrency("1", "INR", "USD");`

This is the code my application uses for the google currency api; what would be the code I should use for the free currency converter api? Nothing I've tried works.

function convert($from,$to,$amount) {

    $url = "https://finance.google.com/bctzjpnsun/converter?a=1&from=" . $from . "&to=" . $to;
    $page = file_get_contents($url);
    preg_match_all("/bld>(.*) .*/", $page, $matches);

    $value = $matches[1][0];

    $response = (float) $value * $amount;

    return $response;

}

Fixed:

function convert($from,$to,$amount){
    $url = "https://www.google.com/search?q=".$from.$to;
    $request = curl_init();
    $timeOut = 0;
    curl_setopt ($request, CURLOPT_URL, $url);
    curl_setopt ($request, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt ($request, CURLOPT_USERAGENT,"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/68.0.3440.106 Safari/537.36");
    curl_setopt ($request, CURLOPT_CONNECTTIMEOUT, $timeOut);
    $response = curl_exec($request);
    curl_close($request);

    preg_match('~<span [^>]* id="knowledge-currency__tgt-amount"[^>]*>(.*?)</span>~si', $response, $finalData);
    return floatval((floatval(preg_replace("/[^-0-9\.]/","", $finalData[1]))/100) * $amount);
}

Thank you, Alisson, this works like a charm. The only thing was I had to delete "/100" in the last line.

Thanks a lot @alissonlinneker.
Though I'd suggest replacing $url with:
$url = "https://www.google.com/search?q=".$from."+to+".$to;
because in some cases like BRL to CAD, Above function was throwing exception.

Need a little help here,
I used above code, tested it on my local environment and it worked smooth as butter, but once I uploaded this to my production environment, it started throwing errors, I debugged and found that Google isn't allowing this code to scrape their data. It gives "302 Moved" Error. Further explanation from Google is: "Our systems have detected unusual traffic from your computer network. Please try your request again later". So, anybody has any tip for that??

Get currency conversion .... https://pastebin.com/TFewge8t

Hello
In above all solutions USD to CNY converter not working

Can you please help me

Thanks!!

Hello
In above all solutions USD to CNY converter not working

Can you please help me

Thanks!!

Yes! Сan you give another solution?

can anyone pls help me with any free currency converter api?

Any solutions!!

It is not the best solution and not very clean, but you can do this:

1. Convert from your old currency to BTC (Bitcoin)
2. Convert your Bitcoin to your new currency! ;-)

Example for 100 EUR to USD:

1. 100 EUR to Bitcoin. Result: 0.01282849
   https://blockchain.info/tobtc?currency=EUR&value=100

2. Convert 01282849 (without "0.") to USD
   https://blockchain.info/frombtc?value=01282849&currency=USD

Attention: In this solution you can convert max 1 full Bitcoin (~8000 EUR)
PHP Code:

function convert($amount, $from, $to)
{
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://blockchain.info/tobtc?currency=" . $from . "&value=" . $amount);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$conversion = curl_exec($ch);
$conversion = substr($conversion, 2);
curl_setopt($ch, CURLOPT_URL, "https://blockchain.info/frombtc?currency=" . $to . "&value=" . $conversion);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
return $conversion = curl_exec($ch);
}
echo convert(100, "EUR", "USD");

Here we are again :(
