whit a static table i haven created this ! www.i.stack.imgur.com/4a3Am.png

I get an array return and it looks like this.:

    "gq_port" => "3812",
    "gq_prot" => "ventrilo",
    "gq_type" => "ventrilo"
)

How can I achieve this ? I have tried many things but nothing with this end result.

what i have now.

$teamArrayConverted['teams'] = convertTeamArray($serverstatus['teams']);
    unset($serverstatus['players'], $serverstatus['teams']);
$results = array_merge_recursive($serverstatus, $teamArrayConverted);

    function convertTeamArray ($array) {
    // First, convert the array so that the keys match the ids
    $reKeyed = array();
    foreach ($array as $item) {
        $reKeyed[(int) $item['cid']] = $item;
    }
    //print_r($reKeyed);    
    // Next, use references to associate children with parents
    foreach ($reKeyed as $id => $item) {
        if (isset($item['pid'], $reKeyed[(int) $item['pid']])) {
          $reKeyed[(int) $item['pid']]['teams'][] =& $reKeyed[$id];
        }
    }
    //print_r($reKeyed);
    // Finally, go through and remove children from the outer level
    foreach ($reKeyed as $id => $item) {
        if ($item['pid'] != '0') {
          //print_r($reKeyed[$id]);
          unset($reKeyed[$id]);
        }
    }
    return array_values($reKeyed);
}

Solution

  • It works in principle like this:

    1. You make each node identifiable by it's numeric id and store it in a hash so it's accessible by it's id.
    2. You take a new hash and insert all elements incl. their children as needed.

    In detail discussion of the code is here: Converting an array from one to multi-dimensional based on parent ID values:

    // key the array by id
    $keyed = array();
    foreach($array as &$value)
    {
        $keyed[$value['id']] = &$value;
    }
    unset($value);
    $array = $keyed;
    unset($keyed);
    
    // tree it
    $tree = array();
    foreach($array as &$value)
    {
        if ($parent = $value['parent_id'])
            $array[$parent]['children'][] = &$value;
        else
            $tree[] = &$value;
    }
    unset($value);
    $array = $tree;
    unset($tree);
    
    var_dump($array); # your result
    

    Replace the names with what you have as variable names and keys.
