Accessing array elements (get_pages)

Question

I'm trying to access the page ID of the child so that I can recursively call the get_children function on that child (to get grandchildren).

    if ($CurrentPage) {
        $args = array(
            'child_of' => $CurrentPage
            );
        $children = get_pages( $args );

        foreach ($children as $key => $value) {
                echo $key.'=>'.$value.'<br />';
        } // End foreach.
    } // End IF. 

I actually get an error: Catchable fatal error: Object of class stdClass could not be converted to string

Answer 1

The return set of $children is an associative array. So you can get the IDs with:

$children = get_children( $args );

foreach ($children as $k => $v) {
    echo $k;
    // do stuff with $v
}
