Multidimensional Array: How to get all values of a specific key? [duplicate]

Question

I have an multidimensional array which includes IDs and URLs. I would like to output the URLs only.

$abstract_details = array(
                        array(
                            'id' => 68769782222,
                            'url' => 'http://yourclick.ch'
                        ),
                        array(
                            'id' => 111,
                            'url' => 'http://google.com'
                        )
                    );

foreach ($abstract_details as $abstract_detail) {
    foreach ($abstract_detail as $get_abstract_detail) {
        $result .= $get_abstract_detail . '<br>';
    }
}

When I run my code I get both information. How is it possible to take control of what I want to show?

Answer 1

Use array_column that will prevent you from foreach loop

$url = array_column($abstract_details, 'url');

echo implode('<br/>', $url);
