Is there a way to programmatically (PHP) generate Azure SaS token for File share?

Question

On our server we need to generate SAS token for File share. Hence we need it in this format.

The Azure Storage PHP client libraries will be retired on 17 March 2024. I was able to find a sample of how to do this programmatically for Azure Files. Please check and let me know if this works for you.

    // Create a SharedAccessSignatureHelper
    global $connectionString;

    $settings = StorageServiceSettings::createFromConnectionString($connectionString);
    $accountName = $settings->getName();
    $accountKey = $settings->getKey();

    $helper = new FileSharedAccessSignatureHelper(
        $accountName,
        $accountKey
    );

    // Generate a file readonly SAS token
    // Refer to following link for full candidate values to construct a service level SAS
    // https://docs.microsoft.com/en-us/rest/api/storageservices/constructing-a-service-sas
    $sas = $helper->generateFileServiceSharedAccessSignatureToken(
        Resources::RESOURCE_TYPE_FILE,
        "$shareName/$fileName",
        'r',                        // Read
        '2030-01-01T08:30:00Z'      // A valid ISO 8601 format expiry time
    );

    $connectionStringWithSAS = Resources::FILE_ENDPOINT_NAME .
        '='.
        'https://' .
        $accountName .
        '.' .
        Resources::FILE_BASE_DNS_NAME .
        ';' .
        Resources::SAS_TOKEN_NAME .
        '=' .
        $sas;

    $fileClientWithSAS = FileRestProxy::createFileService(
        $connectionStringWithSAS
    );

    // Get a downloadable file URL
    $fileUrlWithSAS = sprintf(
        '%s%s?%s',
        (string)$fileClientWithSAS->getPsrPrimaryUri(),
        "$shareName/$fileName",
        $sas
    );

Hope this helps! Let me know if you have any questions.
