- Required extension for PHP:

    - php\_fileinfo.dll
    - php\_mbstring.dll

Download Source Code
--------------------

[](#download-source-code)

To get the source code from GitHub, type

```
git clone https://github.com/Azure/azure-storage-php.git
cd ./azure-storage-php
```

Install via Composer
--------------------

[](#install-via-composer)

1. Create a file named **composer.json** in the root of your project and add the following code to it:

```
{
  "require": {
    "microsoft/azure-storage-blob": "*",
    "microsoft/azure-storage-table": "*",
    "microsoft/azure-storage-queue": "*",
    "microsoft/azure-storage-file": "*"
  }
}
```

1. Download **[composer.phar](http://getcomposer.org/composer.phar)** in your project root.
2. Open a command prompt and execute this in your project root

```
php composer.phar install
```

Usage
-----

[](#usage)

There are four basic steps that have to be performed before you can make a call to any Microsoft Azure Storage API when using the libraries.

- First, include the autoloader script:

```
require_once "vendor/autoload.php";
```

- Include the namespaces you are going to use.

    To create any Microsoft Azure service client you need to use the rest proxy classes, such as **BlobRestProxy** class:

```
use MicrosoftAzure\Storage\Blob\BlobRestProxy;
```

To process exceptions you need:

```
use MicrosoftAzure\Storage\Common\ServiceException;
```

- To instantiate the service client you will also need a valid [connection string](https://azure.microsoft.com/en-us/documentation/articles/storage-configure-connection-string/). The format is:

```
DefaultEndpointsProtocol=[http|https];AccountName=[yourAccount];AccountKey=[yourKey]
```

Or:

```
BlobEndpoint=myBlobEndpoint;QueueEndpoint=myQueueEndpoint;TableEndpoint=myTableEndpoint;FileEndpoint=myFileEndpoint;SharedAccessSignature=sasToken
```

Or if AAD authentication is used:

```
BlobEndpoint=myBlobEndpoint;QueueEndpoint=myQueueEndpoint;TableEndpoint=myTableEndpoint;FileEndpoint=myFileEndpoint;AccountName=[yourAccount]
```

Note that account name is required.

- Instantiate a client object - a wrapper around the available calls for the given service.

```
$blobClient = BlobRestProxy::createBlobService($connectionString);
$tableClient = TableRestProxy::createTableService($connectionString);
$queueClient = QueueRestProxy::createQueueService($connectionString);
$fileClient = FileRestProxy::createFileService($connectionString);
```

Or for AAD authentication:

```
$blobClient = BlobRestProxy::createBlobServiceWithTokenCredential($token, $connectionString);
$queueClient = QueueRestProxy::createQueueServiceWithTokenCredential($token, $connectionString);
```

Note that Blob and Queue service supports AAD authentication.

### Using Middlewares

[](#using-middlewares)

To specify the middlewares, user have to create an array with middlewares and put it in the `$requestOptions` with key 'middlewares'. The sequence of the array will affect the sequence in which the middleware is invoked. The `$requestOptions` can usually be set in the options of an API call, such as `MicrosoftAzure\Storage\Blob\Models\ListBlobOptions`.

The user can push the middleware into the array with key 'middlewares' in services' `$_options` instead when creating them if the middleware is to be applied to each of the API call for a rest proxy. These middlewares will always be invoked after the middlewares in the `$requestOptions`. e.g.:

```
$tableClient = TableRestProxy::createTableService(
    $connectionString,
    $optionsWithMiddlewares
);
```

Each of the middleware should be either an instance of a sub-class that implements `MicrosoftAzure\Storage\Common\Internal\IMiddleware`, or a `callable` that follows the Guzzle middleware implementation convention.

User can create self-defined middleware that inherits from `MicrosoftAzure\Storage\Common\Internal\Middlewares\MiddlewareBase`.

Retrying failures
-----------------

[](#retrying-failures)

You can use bundled middlewares to retry requests in case they fail for some reason. First you create the middleware:

```
$retryMiddleware = RetryMiddlewareFactory::create(
    RetryMiddlewareFactory::GENERAL_RETRY_TYPE,  // Specifies the retry logic
    3,  // Number of retries
    1000,  // Interval
    RetryMiddlewareFactory::EXPONENTIAL_INTERVAL_ACCUMULATION,  // How to increase the wait interval
    true  // Whether to retry connection failures too, default false
);
```

Then you add the middleware when creating the service as explained above:

```
$optionsWithMiddlewares = [
    'middlewares' = [
        $retryMiddleware
    ],
];
$tableClient = TableRestProxy::createTableService(
    $connectionString,
    $optionsWithMiddlewares
);
```

Or by pushing it to the existing service:

```
$tableClient->pushMiddleware($retryMiddleware);
```

Following errors are not retried in current retry middleware:

- Authentication failures.
- "Resource Not Found" errors.
- Guzzle request exceptions that does not bear an HTTP response, e.g. failed to open stream, or cURL Connection reset by peer, etc. *Note:* Community contribution to cover the Guzzle request exceptions are welcomed.

### Retry types

[](#retry-types)

- `RetryMiddlewareFactory::GENERAL_RETRY_TYPE` - General type of logic that handles retry
- `RetryMiddlewareFactory::APPEND_BLOB_RETRY_TYPE` \* For the append blob retry only, currently the same as the general type

### Interval accumulations

[](#interval-accumulations)

- `RetryMiddlewareFactory::LINEAR_INTERVAL_ACCUMULATION` - The interval will be increased linearly, the *nth* retry will have a wait time equal to *n \* interval*
- `RetryMiddlewareFactory::EXPONENTIAL_INTERVAL_ACCUMULATION` - The interval will be increased exponentially, the *nth* retry will have a wait time equal to *pow(2, n) \* interval*

### Using proxies

[](#using-proxies)

To use proxies during HTTP requests, set system variable `HTTP_PROXY` and the proxy will be used.

Troubleshooting
---------------

[](#troubleshooting)

### Error: Unable to get local issuer certificate

[](#error-unable-to-get-local-issuer-certificate)

cURL can't verify the validity of Microsoft certificate when trying to issue a request call to Azure Storage Services. You must configure cURL to use a certificate when issuing https requests by the following steps:

1. Download the cacert.pem file from [cURL site](http://curl.haxx.se/docs/caextract.html).
2. Then either:

    - Open your php.ini file and add the following line:

        ```
        curl.cainfo = ""
        ```

        OR
    - Point to the cacert in the options when creating the Relevant Proxy.

        ```
        //example of creating the FileRestProxy
        $options["http"] = ["verify" => ""];
        FileRestProxy::createFileService($connectionString, $options);
        ```

Migrate from [Azure SDK for PHP](https://github.com/Azure/azure-sdk-for-php/)
-----------------------------------------------------------------------------

[](#migrate-from-azure-sdk-for-php)

If you are using [Azure SDK for PHP](https://github.com/Azure/azure-sdk-for-php/) to access Azure Storage Service, we highly recommend you to migrate to this SDK for faster issue resolution and quicker feature implementation. We are working on supporting the latest service features as well as improvement on existing APIs.

For now, Microsoft Azure Storage PHP client libraries share almost the same interface as the storage blobs, tables, queues and files APIs in Azure SDK for PHP. However, there are some minor breaking changes need to be addressed during your migration. You can find the details in [BreakingChanges.md](BreakingChanges.md).
