i have php files in subfolder. how write app.yaml that.

as described here can use notation match root path, ends .php, php script

# serve php scripts. - url: /(.+\.php)$   script: \1 

this config assume each url ends .php, can modify url regex catch urls (i test regex think it's works :) )

# serve php scripts. - url: /((.+\/).*)$   script: \1.php 

or can simulate httpd mod_rewrite described here.
