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

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?

To get the url: `foreach ($abstract_details as $abstract_detail) { echo $abstract_detail['url'] . '
';}`. Run it: [https://eval.in/605347](https://eval.in/605347) — FirstOne, Jul 14 '16 at 13:13

@FirstOne I don't even know why I thought that it needs to be complicated but that just works fine. Thank you ;) — Reza, Jul 14 '16 at 13:21

Use array_column that will prevent you from foreach loop

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

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

You could simply implode the array. I really appreciate the use of array_column. Using foreach would ruin the former. :) – Indrasis Datta Jul 14 '16 at 13:22

This is a nice function. Thanks for sharing! – Reza Jul 14 '16 at 13:54

You don't even need nested loop here, if you want to print only the url. Try this:

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

Output:

http://yourclick.ch
http://google.com
