Need an example for generating SAS token for Blob storage in PHP with REST API

Luca Marchal 20

Hi there,

I have a PHP (Laravel) + React.js (with Intertia) app that I'm building that needs to use Azure Blob Storage for image uploading and serving images. I've successfully built an uploader on the frontend that relies on a SAS token. My intent was to use the Valet Key pattern to generate this SAS token from the PHP backend, and serve it to the frontend when the page is rendered (I'm using Socialite on the PHP / Laravel side for authentication with Entra ID).

Now the PHP storage client libraries are being retired, and we're forced to use the raw REST API, I'm really struggling to generate the SAS key on the server side for my valet key pattern. I haven't been able to find a single example online of someone else who's successfully integrated the REST API.

Really struggling here and could do with some guidance and / or an example.

Thanks,

Luca

Hi just a heads up, this SO answer includes usage of the deprecated PHP blob storage client which I was avoiding, as I'm looking to build something that's maintainable. I managed to get it to work with the REST API just fine in the end, but am now having issues with the block blob upload. Please check out my latest question

@Luca Marchal , Just checking in. How did you solve this issue? Did you use the SDK in the end for the SAS token generation?

There is now a maintained community alternative to the retired Microsoft PHP storage package, so you do not have to hand-build the full Blob REST signing flow unless you want to.

For PHP applications, especially Laravel valet-key style flows, the practical replacement is azure-oss/storage-blob:

https://packagist.org/packages/azure-oss/storage-blob

Docs:

https://php-oss-for-azure.github.io/storage-blob/core

Migration guide from the retired package:

https://php-oss-for-azure.github.io/storage-blob/migrate-from-microsoft-azure-storage-blob

If the goal is specifically SAS generation from PHP for Blob upload/read flows, I’d recommend pointing people there rather than telling them the only option is raw REST API code.
