I wanted to output a 3 dimensional array that will come from the Database. This is my database looks like:
Basically, I wanted my first array will be the header_name and under the header_name the sub_header_name will come then underneath is the name
eg:
User Role Management => array(
'' => array (
'Create User Role'
)
),
Config Management => array(
'Organisation' => array('Create Country','Create
Organisation'),
'Site' => array('Create Site','Edit Site')
)
and here are my codes:
$getAllPermission = Permission::get();
$arrHeader = array();
$arrSubHeader = array();
$arrPermissions = array();
// $x = 0;
foreach($getAllPermission as $value){
$title = $value->header_name;
$sub_header_name = $value->sub_header_name;
$permission_name = $value->name;
if ($sub_header_name == ""){
$sub_header_name = 0;
}
array_push($arrPermissions,$permission_name);
$arrHeader[$title] = array($sub_header_name => array($arrPermissions));
//$x++;
}
and my output was like this:

You're pushing onto the same $arrPermissions array every time through the loop, that's why each of the roles gets a longer and longer copy of the permissions array.
You're overwriting $arrHeader[$title] each time through the loop instead of adding a new key to it.
Your desired output has a key of '' for the empty sub_header_name, so I don't see why you have the if that sets $sub_header_name = 0;.
It should simply be:
foreach ($getAllPermissions as $value) {
$arrHeader[$value->header_name][$value->sub_header_name][] = $value->name;
}
