PHP从多维数组中删除数组

Question

I build menu on the backend, populated by an array and sub-arrays. The structure is on config.php ..

$primary_nav = array(
   array(
        'name'  => 'Μέλη',
        'url'   => 'member_list.php',
        'icon'  => 'fa fa-users',
        'access'=> 0
    ),array(
        'name'  => 'Ημερίδες',
        'url'   => ($usr['access_level'] == 1) ? 'imerides_list.php':'javascript:void(0)',
        'icon'  => 'fa fa-bullhorn',
        'access'=> 1
    )
);

On Class Users, where it retrieves the access level, i added

if($row['access_level'] != 1){
    unset($primary_nav[1]);
}

How can i do it like, if access level == 1 , remove the array parent ?

I tried unset($primary_nav[1]) and array_slice but they are not working.

抱歉，人们，我只是注意到，我是说，Class Users，它是 Class Users，而 user 是公共函数，而不是传入 $primary_nav，这就是为什么它没有看到要取消设置的数组的原因...

You can do as following:

$primary_nav = array(
   array(
        'name'  => 'Μέλη',
        'url'   => 'member_list.php',
        'icon'  => 'fa fa-users',
        'access'=> 0
    ),array(
        'name'  => 'Ημερίδες',
        'url'   => 'test',
        'icon'  => 'fa fa-bullhorn',
        'access'=> 1
    )
);

foreach($primary_nav as $index=>$obj){
    if($obj['access']==1){
        unset($primary_nav[$index]);
    }
}

print_r($primary_nav);
