Question

I am trying to Json decode something and get the value I want.
But I get PHP undefined index error.
This is my code.

<?php
$json = '[{"totalGamesPlayed":25,"championId":0}]';
$data = json_decode($json,true); 

$games = $data['totalGamesPlayed'];
echo $games;
?>

The problem is the “[” “]” are messing with my code…
I am using an API to get some values.
What I get is this : http://pastebin.com/XrqkAbJf
I need the totalGamesPlayed,the champion ID’s except zero (82,106 and 24)
and the TOTAL_SESSIONS_WON and TOTAL_SESSIONS_LOST for these ID’s…
For a start, let’s find out how can I bypass the “[” and “]” symbols,and then things may be easier..
Thank you in advance!

Access your code like this

$games = $data[0]['totalGamesPlayed'];

Code for getting other info

<?php

$json = 'PUT YOUR EXAMPLE JSON HERE';
$data = json_decode($json,true); 

$seasonWon = 0;
$seasonPlayed = 0;
foreach($data as $stats) {
    if($stats['championId'] != 0) {
        echo '<br><br>Total Games Played:'. $stats['totalGamesPlayed'];    
        echo '<br>champion Ids :'.$stats['championId'];
        foreach($stats['stats'] as $stat) {
            if($stat['statType'] == 'TOTAL_SESSIONS_WON') {
                $seasonWon = $stat['value'];
                echo '<br>TOTAL_SESSIONS_WON :'.$seasonWon;
            }

            if($stat['statType'] == 'TOTAL_SESSIONS_LOST')
            echo '<br>TOTAL_SESSIONS_LOST :'.$stat['value'];

            if($stat['statType'] == 'TOTAL_SESSIONS_PLAYED') {                
                $seasonPlayed = $stat['value'];
                echo '<br>TOTAL_SESSIONS_PLAYED :'.$seasonPlayed;                
            }
        }
        echo '<br>Games Ratio(TOTAL_SESSIONS_WON / TOTAL_SESSIONS_PLAYED): ('. $seasonWon.'/'.$seasonPlayed.'):'. ($seasonWon/$seasonPlayed);
    }
}
