PHP reading json data - php

Question

I'm new to PHP and web programming at all.I am trying to read some json data from steam API.
Data: http://pastebin.com/hVWyLrfZ
I managed to get to single objects(I believe?).
This is my code:
<?php
$url = 'https://api.steampowered.com/IEconDOTA2_570/GetHeroes/v0001/?key=X';
$JSON = file_get_contents($url);
$data = json_decode($JSON);
$heroes = reset(reset($data));
//var_dump($heroes);
$wat = reset($heroes);
$antimage = array_values($heroes)[0];
var_dump($antimage);
?>
I want data to be in array like this:
id => name
I mean, array keys should be ids and values should be hero names.
Also,the where I set heroes variable to reset(reset($data)) seems like a bad way of doing what I want, maybe there are better ways?

Answer 1

You can use array_map() function to extract both id and names in two separate arrays and then use array_combine() to create a key-value pair array from the previously extracted arrays.
$url = 'https://api.steampowered.com/IEconDOTA2_570/GetHeroes/v0001/?key=X';
$JSON = file_get_contents($url);
$data = json_decode($JSON, true);
$ids = array_map(function($a) {
return $a['id'];
}, $data['result']['heroes']);
$names = array_map(function($a) {
return $a['name'];
}, $data['result']['heroes']);
$heroes = array_combine($ids, $names);
print_r($heroes);

Answer 2

A simpler more obvious solution is to simply loop thru it. From your pastebin, I see that your data is wrapped in two levels of array so ...
$myResult = [];
foreach ($data['result']['heroes'] as $nameId) {
$myResult[$nameId['id']] = $nameId['name'];
}
(No need to do any reset calls; that's a weird way to get the first element of an array)
Note, for this to work, you must apply the tip by #RamRaider
$data = json_decode($JSON, true);
in order for json_decode to return arrays, not StdClass.
