(PHP ActiveX) OneDrive -- List Large Directory

Demonstrates how to get the entire collection of DriveItem children when the collection is large and multiple pages need to be requested. To test this example, I created a DriveItem with 450 children.

Note: This example requires Chilkat v9.5.0.68 or greater.

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

$http = new COM("Chilkat_9_5_0.Http");

// Use your previously obtained access token here:
// See the following examples for getting an access token:
//    Get Microsoft Graph OAuth2 Access Token (Azure AD v2.0 Endpoint).
//    Get Microsoft Graph OAuth2 Access Token (Azure AD Endpoint).
//    Refresh Access Token (Azure AD v2.0 Endpoint).
//    Refresh Access Token (Azure AD Endpoint).

// (Make sure your token was obtained with the FilesRead or Files.ReadWrite scope.)
$http->AuthToken = 'MICROSOFT_GRAPH_ACCESS_TOKEN';

// This example will get the DriveItems in /lots-of-files, which has 450 children..
$http->SetUrlVar('item_path','/lots-of-files');

$json = new COM("Chilkat_9_5_0.JsonObject");
$json->EmitCompact = 0;

// This loop will download DriveItems in sets of 50 until no more exist.
$bGetMore = 1;
// (Add the $top query parameter to define the page size, i.e. the max number of results to return).
$nextLink = 'https://graph.microsoft.com/v1.0/me/drive/root:{$item_path}:/children?$top=50';

while (($bGetMore == 1)) {

    // Get the next chunk of DriveItems
    $resp = $http->quickGetStr($nextLink);
    if ($http->LastMethodSuccess != 1) {
        print $http->LastErrorText . "\n";
        exit;
    }

    // The response should be JSON.
    $json->Load($resp);

    // A successful response should return a status code of 200.
    if ($http->LastStatus != 200) {
        print $json->emit() . "\n";
        print 'Response status = ' . $http->LastStatus . "\n";
        exit;
    }

    // Iterate over the DriveItems in the JSON response:
    $i = 0;
    $numItems = $json->SizeOfArray('value');
    while ($i < $numItems) {
        $json->I = $i;
        print 'name: ' . $json->stringOf('value[i].name') . "\n";
        $i = $i + 1;
    }

    // If a nextLink was included in the JSON, use it to get the next set of 50 DriveItems.
    // Otherwise, exit the loop.
    if ($json->HasMember('\'@odata.nextLink\'') == 1) {
        $nextLink = $json->stringOf('\'@odata.nextLink\'');
        print 'nextLink: ' . $nextLink . "\n";
    }
    else {
        $bGetMore = 0;
    }
