When I have my app.yaml file set to deploy in a flex environment everything works great.

```
runtime: php
env: flex

runtime_config:
  document_root: web

```

When I change the app.yaml file to deploy in a standard environment I get a 500 server error.

```
runtime: php74
env: standard

runtime_config:
  document_root: web

```

Does the yaml file require additional parameters when running a standard environment?
