PHP Array in to comma separated list

Question

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

Array
(
    [0] => Array
        (
            [dToken] => 731fea87ea9dc61f16e93f1ad2b96         


        

Answer 1

You're just about there.

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

Answer 2

callback = function($row){
    return $row['dToken'];
}

implode(",",array_map(callback,$result));

Answer 3

You could just build the string:

$cvsString = '';
$delimiter = '';
foreach($result as $device){
    $cvsString.= $delimiter . $device['dToken'];

    $delimiter = ',';
}

var_dump($cvsString);

Or you could first build in array:

$cvsArray = array();
foreach($result as $device){
    $cvsArray[] = $device['dToken'];
}

var_dump(implode(',', $cvsArray));

Answer 4

To answer the question corresponding to the tile (transform an Array to a list with separator) use the implode function. To generate a CSV I would google php CSV, I'm sure there are already lots of function to do it.
