Reading objects from my array - Cannot use object of type XXXX as array

Question

So I've got the following output;

Array
(
    [0] => Array
        (
            [PlayerID] => 0
            [Nickname] => Alban_Berisha
            [Score] => 420
            [Ping] => 96
        )

    [1] => Array
        (
            [PlayerID] => 1
            [Nickname] => Flaviano_Villegas
            [Score] => 122
            [Ping] => 95
        )

    [2] => Array
        (
            [PlayerID] => 2
            [Nickname] => Tyrone_DeRozan
            [Score] => 0
            [Ping] => 120
        )

    [3] => Array
        (
            [PlayerID] => 3
            [Nickname] => Tage_Thomas
            [Score] => 3
            [Ping] => 246
        )

    [4] => Array
        (
            [PlayerID] => 4
            [Nickname] => Jamal_Williams
            [Score] => 149
            [Ping] => 149
        ) 
)

I want a list containing every PlayerID coupled with the Nickname, but I keep getting various errors. What is the correct way of doing this? I have worked with arrays before but I cannot seem to extract the data from it without getting an error

One of the ways I've tried to do this;

    for(new $x=0; $x<5; $x++)
{
    echo (var_dump($array[$x]["PlayerID"])." ".var_dump($array[$x]["Nickname"]));
}

Show an example of the code you've tried and your expected output. — Ben Fortune

Using PHP 5.5's new array_column() function

$newArray = array_column($originalArray, 'Nickname', 'PlayerID');

or with earlier versions of PHP:

$newArray = array_combine(
    array_map(
        function($value) { return $value['PlayerID']; },
        $originalArray
    ),
    array_map(
        function($value) { return $value['Nickname']; },
        $originalArray
    )
);

What were you trying to do with new x?

<?php
$array = array(
            array('PlayerID' => 0,
                  'Nickname' => 'Alban_Berisha',
                  'Score' => 420,
                  'Ping' => 96
                  ),
            array('PlayerID' => 1,
                  'Nickname' => 'Flaviano_Villegas',
                  'Score' => 122,
                  'Ping' => 95
                  ),
            array('PlayerID' => 2,
                  'Nickname' => 'Tyrone_DeRozan',
                  'Score' => 0,
                  'Ping' => 120
                  ),
            array('PlayerID' => 3,
                  'Nickname' => 'Tage_Thomas',
                  'Score' => 3,
                  'Ping' => 246
                  ),
            array('PlayerID' => 4,
                  'Nickname' => 'Jamal_Williams',
                  'Score' => 149,
                  'Ping' => 149
                  )
            );
print_r($array); 
foreach($array as $arr){
    echo $arr['PlayerID'] .' '.$arr['Nickname'] . "<br />";
}
?>

            [Ping] => 95
        )

    [2] => Array
        (
            [PlayerID] => 2
            [Nickname] => Tyrone_DeRozan
            [Score] => 0
            [Ping] => 120
        )

        (
            [PlayerID] => 3
            [Nickname] => Tage_Thomas
            [Score] => 3
            [Ping] => 246
        )

That's it! I tried the for(x) to see if I could get the first 5 results, however it was far from right. I'm still studying on PHP so I consider every mistake a useful one. Thank you for your answer, it helped me loads!

No problem, glad to have helped. You were almost there, just remove 'new' and dont' use var_dump. for($x=0; $x<5; $x++) { echo ($array[$x]["PlayerID"]." ".$array[$x]["Nickname"]) ."<br/>"; } Though in general, it's better to use foreach to loop through data arrays.

Do you mean you want a new array with player ID and nickname?

If so:

$ouputArray = array();

foreach ($oldArray as $player){
 $ouputArray[$player['PlayerID']] = $player['Nickname'];
}

print_r($outputArray);

$results = array();
foreach ($players as $player) {
    $results[ $player['PlayerID'] ] = $player['Nickname'];
}
