Are there best practices for filtering and combining permission levels in PHP arrays to avoid duplication and confusion?

When filtering and combining permission levels in PHP arrays, it is important to avoid duplication and confusion to ensure that permissions are correctly applied. One way to achieve this is by using array functions like array_unique() to remove duplicate values and array_merge() to combine arrays without duplicating elements. Additionally, using associative arrays with meaningful keys can help clarify the permission levels being set. 

// Example code snippet for filtering and combining permission levels in PHP arrays
$permissions1 = ['read', 'write', 'delete'];
$permissions2 = ['write', 'execute'];

// Remove duplicates and combine permissions
$combinedPermissions = array_unique(array_merge($permissions1, $permissions2));

// Output combined permissions
print_r($combinedPermissions);
