Unable to Access Properties of DriveItem in DriveItemCollectionResponse Object

[huguesbert17]

Issue Summary

When using the Microsoft Graph PHP SDK to retrieve items from a OneDrive directory, the DriveItemCollectionResponse and its nested DriveItem objects expose properties in the print_r() output. However, these properties cannot be accessed programmatically, making it impossible to extract data like name, createdBy, and other fields.

Steps to Reproduce

1. Query OneDrive items using the SDK:

   $response = $graphClient->me()->drive()->items()->get();
   $items = $response->getValue();
   
   // Attempt to access properties
   foreach ($items as $item) {
       $name = $item->name; // Property does not exist or is inaccessible
       $createdBy = $item->createdBy; // Same issue
   }

2. Inspect the object using print_r($response):

   • It shows that properties such as name and createdBy are present in the object structure.

3. Try accessing these properties directly:

   $name = $item->getBackingStore()->get('name'); // Produces inconsistent results or null

4. Attempt to convert the object to JSON or an array:

   function objectToArray($object) {
       if (is_object($object)) {
           $object = get_object_vars($object);
       }
       if (is_array($object)) {
           return array_map('objectToArray', $object);
       }
       return $object;
   }
   
   $data = objectToArray($response); // Results in null values

Expected Behavior

At a minimum, properties like name, createdBy, id, etc., should be accessible programmatically from the DriveItem objects within the DriveItemCollectionResponse.

Actual Behavior

• DriveItem properties cannot be accessed programmatically even though they appear in the object structure when printed using print_r().
• Converting the object to an array or JSON results in null values for most properties.

Workarounds Attempted

1. Direct Access: Accessing properties like $item->name directly results in an error.
2. Using Backing Store: The getBackingStore() method does not reliably return property values.
3. Recursive Conversion: Converting the response to an array using custom functions results in null for properties.

Proposed Solution

• Ensure all properties are accessible programmatically from DriveItem objects.
• Add a built-in method to convert objects to arrays or JSON for easier integration with AJAX-based frontend applications.
• Provide documentation with examples on how to access and use properties programmatically.

Environment

• PHP Version: 8.4.2
• SDK Version: 2.23

Additional Context

• This issue significantly limits the usability of the SDK for modern applications.
• Being unable to access properties programmatically or convert the response to JSON prevents integration with frontend frameworks like React.
• If there is a specific intended way to access these properties, it should be explicitly documented.

@huguesbert17 thank you for reaching out.

The properties are accessible via getters. In the sample provided, getName(), getCreatedBy()
