Why does Azure SDK for PHP not working well with Azure General-purpose Storage


Is Azure SDK for PHP Blob Storage method works only on a Blob Storage account? Because whenever I tried to use it on an Azure General-purpose Storage account (which gives you access to Azure Storage services such as Tables, Queues, Files, Blobs and Azure virtual machine disks under a single account), my php program stops at an specific process in an inconsistent manner. At times it processes completely but when I re-run it, it stops again in a random point.

My goal is to get all blobs under my Azure subscription using foreach loop, given that I have an array variable that holds connection strings for each storage accounts. It works well with a Blob Storage account but whenever I include the General-purpose Storage account, the problem starts to occur.

I already tried overriding my php memory limit and still it does not solve the issue.

Any advise guys? Thank you in advance.
