Thank for your help.

In my test, it seems due to the build in PHP runtime version. I will reproduce your issue if I set the PHP version to 7.1 in Azure portal. But the composer extension will be installed fine if I downgrade the build in PHP version to 7.0.

So currently, you can downgrade the PHP runtime to 7.0 as a workaround. Or try to manually download composer.phar extension in your project.
