I've been using this class I built for a while, so I thought I'd release it to the bitcoin community as I haven't really saw many others like this:
https://github.com/Someguy123/MtGOX-PHP-API

Feel free to try it out, if you find any problems, just post in this thread here, or let me know on IRC: irc.freenode.org #bitcoin-otc #bitcoin - someguy123

Code:

NMC: N5omEguYDarGmHt2R23DFvkXYU49yPAAKN

If the class has helped you in any way, please donate to any of the addresses above ^ even a bitcent is fine :)

NOTE: This class is still using Version 0 of the MtGOX API, this means it could be deprecated at any time, but works right now as of 26/07/2012 despite the API changes

This is excellent, just ran thru the code and really nice work.

I will point this to people who ask us for help with the Gox API.

Thanks, doesn't seem to be getting much attention amazingly enough, even though I always see people asking about using the MtGOX API...
Also does anyone know if I would be able to add a link to my API on https://en.bitcoin.it/wiki/MtGox/API ?

Nice work. Very clear, efficient and well structured code.

You might want to use this as a subclass and have a class wrapper with functions such as placebid($amt,$price), placeask($amt,$price) etc... That's what I have done as it saves you having to add the $path each time you place a call. It'll also make using each function simpler as each function will have a pre-defined set of inputs instead of having to look up the api page to find out what you should put in the $req = array() variable (which could lead to all sorts of mistakes caused by human error).

If I ever get round to tidying up my API code I'll share it one day.

Do you trade using your script?

... I'd be interested to hear from anyone who has written a PHP socket.io class for MtGox!

That's because you're advertising it like a programmer.

I'd bet that traffic to this thread would double if you put "MtGox Bot Source Code" or something in the title.

Here's the class I use to do the same thing:

https://github.com/dooglus/intersango/blob/aud/mtgox_api.php

It's more complete, offering functions like buy_btc, sell_btc, cancel_order, etc.

Use it if you like, but I can't offer any guarantees as to its correctness, but it works well enough for my purposes.

dooglus, how may I execute the functions?

For example there is the function get_funds(), but how and where may I execute it?

Sorry for my dumb questions  Undecided

<?PHP

include "mtgox_api.php";

$inst = new MtGox_API();

echo '<pre>' . print_r($inst->get_funds(),true) . '</pre>';

?>

Also you need to edit the first function in mtgox_api.php

function __construct($key, $secret)
    {
        $this->key = MTGOX_KEY;
        $this->secret = MTGOX_SECRET;
    }

so the vars match mtgox_config.php

BCB, thank you very much... I have never been so close  Grin

But I please you to pardon my noobness : may I ask you what is incorrect in my code?

The following, modified as you told me :

    {
        // generate a nonce as microtime, with as-string handling to avoid problems with 32bits systems
        $mt = explode(' ', microtime());

        // generate the POST data string
        $post_data = http_build_query($req, '', 'name=sandy67&pass=lovebitcoins84');
 
        // generate the extra headers

Okay I was able to fix the first set of errors by putting

Quote
<?php

class MtGox_API
{

    function __construct($key="sdsfdfyssfd-sfdsdf-dsfdfds-fdsdfsfds-fddfsfsd", $secret="fdsgfgffftgrgretzt3355353tet5trr5353")
    ...

bu I then still get

Quote
Fatal error: Uncaught exception 'Exception' with message 'Could not get reply: error setting certificate verify locations: CAfile: ABSPATH/cert/facacbc6.0 CApath: none ' in myserver.com/json.php:42 Stack trace: #0 myserver.com/json.php(187): MtGox_API->query('0/btcAddress.ph...') #1 myserver.com/json.php(213): MtGox_API->get_btc_address() #2 {main} thrown in myserver.com/json.php on line 42

What is wrong there?

Could some1 point me to the solution  Huh Help !

You need to install facacbc6.0 on your server

https://github.com/dooglus/intersango/tree/aud/cert


It is called in the curl option:

curl_setopt($ch, CURLOPT_CAINFO, ABSPATH . "/cert/facacbc6.0");

I am gonna try this little piece of code Smiley

I suppose that this file should be adapted with some specific informations, as I saw a kind of PGP encoding inside?

So is there any PHP-based class for socket.io-based MtGox API?

Just a note guys: Apparantly this still works, MtGox hasn't removed the version 0 API yet, so the wrapper should still function without error.
