PHP getting values of the objects by key inside array

Question

Hi all I have an array "$decodedData" of object from json data.

var_export($decodedData);

returns next:

array ( 0 => array ( 'number' => '2', 'type' => 'accs', ), 1 => array ( 'number' => '5', 'type' => 'accs', ), )

I'm trying to output all the "numbers" values:

foreach ($decodedData as $number)
{
    echo implode(',', $number);
}

but I'm getting "type" values either

2,accs5,accs

How can I get rid of those?

Have you read the PHP docs for foreach? There is a way to get the key and value. — Justin Wood

You can use array_map to accomplish that.

The first parameter is a callback function that will receive each element and return something to replace it with. In this case, we are returning the number key of each element.

$result = array_map(function($val) {
    return $val['number'];
}, $array);

echo implode(',', $result);

You're looping through an array of arrays, so $number is returning a complete array, not the number value. To access the number value of each, do something like this:

foreach ($decodedData as $number=>$val){
    echo implode(',', $val['number']);
}
