PHP数组以逗号分隔列表

Question

I have a list of items from a database being parse in an array

Array
(
    [0] => Array
        (
            [dToken] => 731fea87ea9dc61f16e93f1ad2b964bf1926633acac151c1853ab91ea0465228
            [0] => 731fea87ea9dc61f16e93f1ad2b964bf1926633acac151c1853ab91ea0465228
        )

    [1] => Array
        (
            [dToken] => d890a5002f7da8bd35f6cae50e597d6f11554b26ba686bc7314afe77d1b36a61
            [0] => d890a5002f7da8bd35f6cae50e597d6f11554b26ba686bc7314afe77d1b36a61
        )

)

I need to get all of the dTokens and list them out in a variable with each dToken seperated by a comma except the last in the list.

foreach($result as $device['dToken'] => $token){
    //$devices = $token['dToken'];
    print_r($token['dToken']);
}

Any help please?

You're just about there.

$tokens = array();
foreach($result as $device){
    $tokens[] = $device['dToken'];
}
echo implode(',', $tokens);
