+## Quick Example for a PHP Function (4 minutes)
+
+This example will show you how to test and deploy Go (Golang) code to Oracle Functions.
+
+### 1. Prepare the `func.yaml` file:
+
+At func.yaml you will find:
+
+```yml
+name: USERNAME/hello
+version: 0.0.1
+path: /hello
+build:
+- docker run --rm -v "$PWD":/worker -w /worker funcy/php:dev composer install
+```
+
+The important step here is to ensure you replace `USERNAME` with your Docker Hub account name. Some points of note:
+the application name is `phpapp` and the route for incoming requests is `/hello`. These informations are relevant for
+the moment you try to test this function.
+
+### 2. Build:
+
+```sh
+# build the function
+fn build
+# test it
+cat hello.payload.json | fn run
+# push it to Docker Hub
+fn push
+# Create a route to this function on Oracle Functions
+fn routes create phpapp /hello
+```
+
+`-v` is optional, but it allows you to see how this function is being built.
+
+### 3. Queue jobs for your function
+
+Now you can start jobs on your function. Let's quickly queue up a job to try it out.
+
+```sh
+cat hello.payload.json | fn call phpapp /hello
+```
+
+Here's a curl example to show how easy it is to do in any language:
+
+```sh
+curl -H "Content-Type: application/json" -X POST -d @hello.payload.json http://localhost:8080/r/phpapp/hello
+```
