Getting data in a PHP Array

Question

Today I'm trying to get some datas from an PHP array but I don't know how to do this because I'm not supposed to know the name of the first key.

Array
(
[5bnuQsT1Y4S9yk8LRhBeLtT5PWqoAYrv2XlIGu1A] => Array
    (
        [token] => TeamSpeak3_Helper_String Object
            (
                [string:protected] => 5bnuQsT1Y4S9yk8LRhBeLtT5PWqoAYrv2XlIGu1A
                [position:protected] => 0
            )

        [token_type] => 0
        [token_id1] => 8
        [token_id2] => 0
        [token_created] => 1465668613
        [token_description] => 
    )

[df01kyz5BWtgFXDFT+70g5oSze2e3WijYEfbOSDO] => Array
    (
        [token] => TeamSpeak3_Helper_String Object
            (
                [string:protected] => df01kyz5BWtgFXDFT+70g5oSze2e3WijYEfbOSDO
                [position:protected] => 0
            )

        [token_type] => 0
        [token_id1] => 8
        [token_id2] => 0
        [token_created] => 1465668966
        [token_description] => 
    )

 )

I would like to get the value of each key called [string:proected]

I tried to vardump this : $array[0][0] and this : $array[0] but they are set to NULL.

When I do vardump($array["5bnuQsT1Y4S9yk8LRhBeLtT5PWqoAYrv2XlIGu1A"]["token"] I get only the object, but I still need to set a loop to get all the strings.

Can you help me with that?

Thanks!

foreach loop might help if the structure of the array is same. — phraniiac

reset( $array ) php.net/manual/en/function.reset.php, to get the first element of an array, for each string:protected, this should help for each — ArtisticPhoenix

You can use a foreach loop to grab each index out of the array like this:

<?php

$data = array (
    '5bnuQsT1Y4S9yk8LRhBeLtT5PWqoAYrv2XlIGu1A' => array (
        'token' => array (
            'string:protected' => '5bnuQsT1Y4S9yk8LRhBeLtT5PWqoAYrv2XlIGu1A',
            'token_type' => 0,
            'token_id1'=> 8,
            'token_id2' => 0,
            'token_created' => 1465668613,
            'token_description' => '',
        ),
    ),
    'df01kyz5BWtgFXDFT+70g5oSze2e3WijYEfbOSDO' => array (
        'token' => array (
            'string:protected' => 'df01kyz5BWtgFXDFT+70g5oSze2e3WijYEfbOSDO',
            'token_type' => 0,
            'token_id1'=> 8,
            'token_id2' => 0,
            'token_created' => 1465668966,
            'token_description' => '',
        ),
    ),
);

foreach($data as $index => $value) {
    echo $data[$index]['token']['string:protected'] . '<br>';
}

Oh thanks you it's work! But can you explain to me why if I write : echo $data[0]['token']['string:protected'] . '<br>'; it does't work ?

because $data[0] dose not exist. its $data[5bnuQsT1Y4S9yk8LRhBeLtT5PWqoAYrv2XlIGu1A], you can do key($array) to get the current key, and reset($array), next(), prev(), end() to get value and more the pointer. Or just use a loop.

Exactly - it's an associative array - associative arrays do not have numerical indices, but only the string index provided. Using this method is smart! :)

Okay I understand now :) Thanks you for your help!

you could do array_values( $array ) and then the number, but you lose the top level keys. And that doesn't explain why you cant get the 0 index, it just makes a new array using only the values of the input array.
