There is some kind of type hinting in function arguments declaration since PHP 5.1, so... since 2005?

Since when can you specify the array keyword before variable declaration in a function's arguments?

This is a project I just recently started. It's written in PHP, upload the script somewhere and run it through your browser.

It shows when there is arbitrage available within the BTC-e exchange itself. It does nothing else yet, I'm still working on getting automatic trades executed. Fees are automatically calculated. If I've missed something here as far as the actual calculations go please let me know. Yes, I'm aware it's only going off last price at the moment, it's going to be able to calculate using the whole order book soon. It's sloppy and quite awful, but I've only just started. I've had good luck with it during the night when prices tend to jump around a bit more, and conversions through RUR/EUR seem to yield the best results.

Code:
function btce_query($method, array $req = array()) {
        static $ch = null;
        if (is_null($ch)) {
                $ch = curl_init();
                curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
                curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; BTCE PHP client; '.php_uname('s').'; PHP/'.phpversion().')');
        }
        curl_setopt($ch, CURLOPT_URL, 'https://btc-e.ru/tapi/');
        curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
 
        // run the query
        $res = curl_exec($ch);
        if ($res === false) throw new Exception('Could not get reply: '.curl_error($ch));
        $dec = json_decode($res, true);
        if (!$dec) throw new Exception('Invalid data received, please make sure connection is working and requested API exists');
        return $dec;
}


function GetJsonFeed($json_url)
{
    $feed = file_get_contents($json_url);
    return json_decode($feed, true);
}
$BTC_RUR = GetJsonFeed("http://btc-e.com/api/2/btc_rur/ticker");
