How will i be able to get a single value out of BTC-e API using PHP?. This is the current API that i can use.
https://btc-e.com/api/3/ticker/btc_usd
As you can see, it shows lots of information, but i dont need many information that is displayed there. What can i do so that i will only get
"last":284.323
this number?
Thank you for your help regarding this subject.
分享 As you can see, the received data is a JSON value.
If you simply want to receive data from a website, you can use the file_get_contents function.
With the json_decode function, you can create an object from this data.
If you're looking for a specific value, you maybe can use print_r to get a clarifying list of the given data.
When you use the print_r function on the given data, it will return:
stdClass Object
(
[btc_usd] => stdClass Object
(
[high] => 288.957
[low] => 272.00201
[avg] => 280.479505
[vol] => 2178508.65397
[vol_cur] => 7771.83325
[last] => 286.322
[buy] => 286.328
[sell] => 286.322
[updated] => 1445787588
)
)
As you can see, you are looking for a variable stored in ->btc_usd->last
So when it all comes together, you can use the following:
<?php
# Get String
$_ApiString = '{"btc_usd":{"high":288.957,"low":272.00201,"avg":280.479505,"vol":2178508.65397,"vol_cur":7771.83325,"last":286.322,"buy":286.328,"sell":286.322,"updated":1445787588}}';
# Or maybe you simply want to download it from a website
$_ApiString = file_get_contents('https://btc-e.com/api/3/ticker/btc_usd');
# Create object from ApiString
$_Object = json_decode($_ApiString);
# Get variable
$_Last = $_Object->btc_usd->last;
?>
