This is the json that deepbit.net returns for my Bitcoin Miner worker. I'm trying to access the workers array and loop through to print the stats for my [email protected] worker. I can access the confirmed_reward, hashrate, ipa, and payout_history, but i'm having trouble formatting and outputting the workers array.
{
"confirmed_reward":0.11895358,
"hashrate":236.66666667,
"ipa":true,
"payout_history":0.6,
"workers":
{
"[email protected]":
{
"alive":false,
"shares":20044,
"stales":51
}
}
}
Thank you for your help :)

Firstly read the contents of the text file into a string variable using the file_get_contents() function and then use json_decode() function to convert the JSON string to a PHP variable. $filepath = './persons. txt'; $json_string = file_get_contents($filepath); $json = json_decode($json_string, true);
Looping through multidimensional arrays Just as with regular, single-dimensional arrays, you can use foreach to loop through multidimensional arrays. To do this, you need to create nested foreach loops — that is, one loop inside another: The outer loop reads each element in the top-level array.
Reading JSON From a File or String in PHP First, you need to get the data from the file into a variable by using file_get_contents() . Once the data is in a string, you can call the json_decode() function to extract information from the string.
PHP File explained:Convert the request into an object, using the PHP function json_decode(). Access the database, and fill an array with the requested data. Add the array to an object, and return the object as JSON using the json_encode() function.
I assume you've decoded the string you gave with json_decode method, like...
$data = json_decode($json_string, TRUE);
To access the stats for the particular worker, just use...
$worker_stats = $data['workers']['[email protected]'];
To check whether it's alive, for example, you go with...
$is_alive = $worker_stats['alive'];
It's really that simple. )
