Get Blob directory name in azure storage in php - php

Question

I want to create directory and sub directory in azure storage from php and get that directory. This is my code.
$blobRestProxy = ServicesBuilder::getInstance()->createBlobService($connection_string);
$content = fopen("abc.txt", "r");
$blob_name = "dir1/dir2/di3/myblob";
try {
//Upload blob
$blobRestProxy->createBlockBlob("mycontainer", $blob_name, $content);
}
catch(ServiceException $e){
// Handle exception based on error codes and messages.
// Error codes and messages are here:
// http://msdn.microsoft.com/library/azure/dd179439.aspx
$code = $e->getCode();
$error_message = $e->getMessage();
echo $code.": ".$error_message."<br />";
}
I want to get directory "dir1".I checked that example How to create a sub container in azure storage location.
But it's not in php. Can any one help me how can we create and get directory in azure from PHP code.

You can use ListBlobsOptions to set specially object when querying Blobs from container. Per your requirement, you can use the setDelimiter('/') of this options to set the delimiter as to separate the virtual directory from blob names.
And to use getBlobPrefixes() to get the virtual directory names from ListBlobsResult which is the result of listBlobs() function.
Please consider the following code snippet:
use MicrosoftAzure\Storage\Blob\Models\ListBlobsOptions;
$listBlobsOptions = new ListBlobsOptions();
$listBlobsOptions->setDelimiter('/');
$result = $blobClient->listBlobs(<container_name>, $listBlobsOptions);
foreach ($result->getBlobPrefixes() as $k => $b) {
//an instance of MicrosoftAzure\Storage\Blob\Models\BlobPrefix
array_push($return['blobPrefixes'], $b->getName());
}
And here is a sample about how to use the modules in Azure Staoge SDK for PHP. You can have a full glance of the usage from https://github.com/Azure-Samples/storage-blob-php-webapplication/blob/master/PHP/api/trial.php#L163.
