Hi @Ytowait Pvt Ltd

You should be able to go into the app service and set the Major version to PHP5:

In App Service > Setting > Configuration > General Settings > Major Version > Choose PHP5

PHP on App Service (Documentation)

@Ytowait Pvt Ltd Thank you for reaching out to Microsoft Q&A. Apologize for the any inconvenience caused on this.

As mentioned here in this GIT hub article, PHP 5.6 is end of life on Azure app service and app service currently supports PHP 7.4 or PHP 8.0 only. I would recommend you upgrade the PHP versions of your app to supported version on web app accordingly.

Adding to the @Dillon Silzer suggestion, alternatively using Azure CLI cmdlet you can change run time PHP versions of the existing web app.

az webapp config set --resource-group <ResourceGroupName> --name <WebAppName> --linux-fx-version "PHP|7.4"  

If you are creating the webapp from the portal, you can select lower versions(available is PHP 7.4) of the supported runtime using the dropdown as shown below.

Feel Free to reach back to me if you have any questions on this.

Your only hope out there is to build your own Docker image based on the PHP 5.6 Docker image you can find (several un-official there, so use with caution and accept the risks). Then this image can be used to deploy your web app on Azure App Service or Azure Kubernetes Service.
