Create a basic PHP app with a front controller
Back to home
On this page
To handle dynamic requests to your PHP app, you might want to use a front controller. The following example shows how for such an app you might start defining your web server.
Define a document root 
Start by defining your document root (where all your publicly visible pages are).
web:
locations:
'/':
root: 'public' Define a front controller
Define where all requests that don’t match a file in the document root are sent.
web:
locations:
'/':
root: 'public'
passthru: '/index.php'
index:
- index.phpIn this case, /index.php acts as a front controller and handles dynamic requests.
Because it handles dynamic requests, you want to ensure that scripts are enabled and responses aren’t cached.
web:
locations:
'/':
...
scripts: true
# No caching for static files.
# (Dynamic pages use whatever cache headers are generated by the program.)
expires: -1 Define rules
You might want to define specific rules for the location. For example, you might want to allow all kinds of files except mp4 files.
web:
locations:
'/':
...
# Allow all file types generally
allow: true
rules:
# Disallow .mp4 files specifically.
\.mp4$:
allow: false Set different rules for specific locations
You might want to set specific rules for specific locations.
For example, you might have files in your /public/images directory that are served at /images.
You could define a specific cache time for them and limit them to only static image files.
web:
locations:
'/':
...
# Set a 5 min expiration time for static files in this location.
# Missing files are sent to front controller
# through the '/' location above.
'/images':
expires: 300
passthru: true
# Do not execute PHP scripts from this location and do not
# deliver their source code (for enhanced security).
scripts: false
allow: false
rules:
# Only allow static image files in this location
'\.(jpe?g|png|gif|svgz?|ico|bmp)$':
allow: true Complete example
web:
locations:
'/':
root: 'public'
passthru: '/index.php'
index:
- index.php
scripts: true
# No caching for static files.
# (Dynamic pages use whatever cache headers are generated by the program.)
expires: -1
# Allow all file types generally
allow: true
rules:
# Disallow .mp4 files specifically.
\.mp4$:
allow: false
# Set a 5 min expiration time for static files in this location.
# Missing files are sent to front controller
# through the '/' location above.
'/images':
expires: 300
passthru: true
# Do not execute PHP scripts from this location and do not
# deliver their source code (for enhanced security).
scripts: false
allow: false
rules:
# Only allow static image files in this location
'\.(jpe?g|png|gif|svgz?|ico|bmp)$':
allow: true
