Is there a function to extract a 'column' from an array in PHP?

Question

I have an array of arrays, with the following structure :

array(array(\'page\' => \'page1\', \'name\' => \'pagename1\')
      array(\'page\' => \'pa         


        

Answer 1

With array_reduce:

$names = array_reduce($array, function ($carry, $item) {
    return array_merge($carry, [$item['name']]);
}, []);
