Please help w/ an easy question:

Note: I'm not looking to need to Authenticate w/ the full API
https://en.bitcoin.it/wiki/MtGox/API#Authentication

1) This URl:
https://mtgox.com/api/0/data/ticker.php
Returns the data in a browser, so it must be possible to do a simple script like this (for example)

Code:
<?php

$jsonurl 
"https://mtgox.com/api/0/data/ticker.php";
$json file_get_contents($jsonurl,0,null,null);
$values json_decode($jsontrue);

echo 
$values['ticker']['sell'];

?>

The above just gives a blank page.
This must be easy, can someone please tell me what is wrong?
Thank you very much.

Code:
<?php
function updateExchangeRate() {
$result False;
$url "https://mtgox.com/api/0/data/ticker.php";

if ($CH curl_init()) {
curl_setopt($CHCURLOPT_URL$url);
curl_setopt($CHCURLOPT_RETURNTRANSFERTrue);
curl_setopt($CHCURLOPT_SSL_VERIFYHOSTFalse);
curl_setopt($CHCURLOPT_SSL_VERIFYPEERFalse);
curl_setopt($CHCURLOPT_TIMEOUT5);
curl_setopt($CHCURLOPT_USERAGENT"MtGox PHP Client");

if ($output curl_exec($CH)) {
if ($result json_decode($outputTrue)) {
if ($result $result['ticker']) {
databaseQuery("UPDATE `mytable`.`misc` SET `value`=:price WHERE `key`='mtgox'"False, array('price' => round($result['last'], 2)));
}
} else {
// JSON decoding failed. //
}
} else {
// cURL connection failed. //
}
} else {
// cURL initialization failed. //
}
$CH NULL;
}
?>

the above saves the price on database, and then i get the updated price each time from database.

you can alter it any way you like, good luck, tell us if it works for you.

...tell us if it works for you.

After the curl, I just needed the variable, so  (for example)

Code:
//decode from an object to array
$output_mtgox = json_decode($mtgoxjson);
$output_mtgox_1 = get_object_vars($output_mtgox);
$mtgox_array = get_object_vars($output_mtgox_1['ticker']);

$ask_price= $mtgox_array['sell'];


Yes that helped, thanks  Smiley

Similar here, learn by example then make changes and learn even more when trying to fix what's broken.   Cheesy
