Question

I have the following php code:

$menu_wood = array();
$menu_wood[] = array('link' => 'holz.php',
            'description' => 'Holzübersicht',
            'class' => isCurrentPage('holz.php')
            );
$menu_wood[] = array('link' => 'ahorn.php',
            'description' => 'Ahorn',
            'class' => isCurrentPage('ahorn.php')
            );
$menu_wood[] = array('link' => 'birke.php',
            'description' => 'Birke',
            'class' => isCurrentPage('birke.php')
            );

Is there a buildin function in PHP that can return an array of all the ‘link’ elements, or do I need to write my own function?

Answer 1

I guess you need to use your own code this way.

$myLinks = array();
foreach ($menu_wood as $menu)
    $myLinks[] = $menu['link'];

If you wanna write a function, you can do so this way:

function getPart($array, $arrIndex)
{
    $myLinks = array();
    foreach ($array as $single)
        $myLinks[] = $menu[$arrIndex];
}
