JqGrid Data from URL - php

Question

I am decoding JSON from an API:
$api = "http://xyzdomain.com/api";
$json = file_get_contents($api);
$array = json_decode($json,true);
print_r($array);
Here is the sample result of API objects and arrays.
Array
(
[status] => ok
[count] => 1
[meta] => Array
(
[count] => 1
)
[data] => Array
(
[accountid] => Array
(
[0] => Array
(
[all] => Array
(
[fans] => 16
[user post] => 333
[user Details] => xyz
)
[scorelist] => 1
[name] => John Doe 1
[timespent] => 5887
[nation] => usa
)
[1] => Array
(
[all] => Array
(
[fans] => 123
[user post] => 903
[user Details] => mno
)
[scorelist] => 6
[name] => John Doe 2
[timespent] => 1269
[nation] => usa
)
[2] => Array
(
[all] => Array
(
[fans] => 16
[user post] => 303
[user Details] => abc
)
[scorelist] => 1
[name] => John Doe 3
[timespent] => 9292
[nation] => ussr
)
[3] => Array
(
[all] => Array
(
[fans] => 16
[user post] => 333
[user Details] => jqr
)
[scorelist] => 1
[name] => John Doe 4
[timespent] => 75600
[nation] => usa
)
)
)
)
I used only three samples above, but it may go up to 500 or more.
I have basically two questions here:
I want to make a table using jqgrid or datatables or any other way it looks good.
How can I sum timespent where nation is, say, USA in above example?

Answer 1

$timespent_usa = 0;
foreach($array['data']['accountid'] as $account) {
if ($account['nation'] == 'usa') {
$timespent_usa += $account['timespent'];
}
}
echo $timespent_usa;
I'm not sure on how you plan on getting the data into datatables, you could just echo the data within each $account array within the foreach loop into <td> elements.
