Transfer objects to and from Azure Blob storage using PHP

This repository contains a simple sample project to help you getting started with Azure storage using .NET as the development language.

Prerequisites

To complete this tutorial:

To complete this quickstart:

• Install PHP
• Install The Azure SDK for PHP

If you don't have an Azure subscription, create a free account before you begin.

Create a storage account using the Azure portal

First, create a new general-purpose storage account to use for this quickstart.

1. Go to the Azure portal and log in using your Azure account.
2. Enter a unique name for your storage account. Keep these rules in mind for naming your storage account:
   • The name must be between 3 and 24 characters in length.
   • The name may contain numbers and lowercase letters only.
3. Make sure that the following default values are set:
   • Deployment model is set to Resource manager.
   • Account kind is set to General purpose.
   • Performance is set to Standard.
   • Replication is set to Locally Redundant storage (LRS).
4. Select your subscription.
5. For Resource group, create a new one and give it a unique name.
6. Select the Location to use for your storage account.
7. Check Pin to dashboard and click Create to create your storage account.

After your storage account is created, it is pinned to the dashboard. Click on it to open it. Under Settings, click Access keys. Select the primary key and copy the associated Connection string to the clipboard, then paste it into a text editor for later use.

Put the connection string in an environment variable

This solution requires a connection string be stored in an environment variable securely on the machine running the sample. Follow one of the examples below depending on your Operating System to create the environment variable. If using windows close out of your open IDE or shell and restart it to be able to read the environment variable.

Linux

export storageconnectionstring="<yourconnectionstring>"

Windows

setx storageconnectionstring "<yourconnectionstring>"

At this point, you can run this application. It creates its own file to upload and download, and then cleans up after itself by deleting everything at the end.

More information

The Azure storage documentation includes a rich set of tutorials and conceptual articles, which serve as a good complement to the samples.

storage-blobs-php-quickstart's Issues

File uploaded to Azure is empty

Please provide us with the following information:

This issue is for a: (mark with an x)

- [x] bug report -> please search issues before submitting
- [ ] feature request
- [ ] documentation issue or request
- [ ] regression (a behavior that used to work and stopped in a new release)

Minimal steps to reproduce

run the application/file phpQS.php

Any log messages given by the failure

none

Expected/desired behavior

the file HelloWorld.txt uploaded to Azure Blob storage should have the text "Hello Azure!" in it, but it is empty.

OS and Version?

Windows 7, 8 or 10. Linux (which distribution). macOS (Yosemite? El Capitan? Sierra?)

Windows 10 Professional

Versions

Mention any other details that might be useful

On line 84 in phpQS.php the call to open the file in "write" mode will essentially truncate the file contents (http://php.net/manual/en/function.fopen.php ):
$myfile = fopen($fileToUpload, "w") or die("Unable to open file!");
Thus when the file is subsequently uploaded to Azure it will be empty.
Since the intention is just to see if the file exists/can be read, the fix would be to use the "read" flag on line 84:
$myfile = fopen($fileToUpload, "r") or die("Unable to open file!");
