                )

I only want to pull ID name totalsessionsplayed , totalsessionslost and totalsessionswon from each array and display it in a table.

I have not yet found a way to make it work.

Answer 1

I think this is what you're looking for:

echo '<table>';
foreach($arr['champions'] as $entry) {
    echo '<tr>';
    echo '<td>' . $entry['id'] . '</td>';
    echo '<td>' . $entry['name'] . '</td>';
    echo '<td>' . $entry['stats']['totalSessionsPlayed'] . '</td>';
    echo '<td>' . $entry['stats']['totalSessionsLost'] . '</td>';
    echo '<td>' . $entry['stats']['totalSessionsWon'] . '</td>';
    echo '</tr>';
}
echo '</table>';

Answer 2

You would access your values like, starting from the champions sub array, then iterate through it with a foreach() :

<?php 
$your_array = ...

foreach($your_array['champions'] as $row){

    //get the values, dont really need to reassign but you get the idea
    $id = $row['id'];
    $name = $row['name'];
    $played = $row['stats']['totalSessionsPlayed'];
    $lost = $row['stats']['totalSessionsLost'];
    $won = $row['stats']['totalSessionsWon'];

    //do something with them values on each iteration
}
?>

Answer 3

You can do a foreach loop in php to get the data you need. I am using $array as the name of your variable where you are holding the array:

foreach($array['champions'] as $thischamp) {
$id = $thischamp['id'];
$name = $thischamp['name'];
$totalsessions = $thischamp['stats']['totalsessionsplayed'];
$totallost = $thischamp['stats']['totalsessionslost'];
$totalwon = $thischamp['stats']['totalsessionswon'];
// now write your html
}
