 ### Note on Dependencies
 
-```yml
+In PHP, you can create a [composer](https://getcomposer.org/) file in your function directory, then run:
-name: USERNAME/hello
+
-version: 0.0.1
+```sh
-path: /hello
+fn build
-build:
-- docker run --rm -v "$PWD":/worker -w /worker funcy/php:dev composer install
 ```
 
+This will rebuild your gems and vendor them. PHP doesn't pick them up automatically, so you'll have to add this to the top of your `func.php` file:
+
+```php
+require 'vendor/autoload.php';
+```
+
+Open `func.php` to see it in action.
+
+
 ### 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.

 2. We received our function input through **stdin**
-    ```node
+    ```php
-    obj = JSON.parse(fs.readFileSync('/dev/stdin').toString())
+    $payload = json_decode(file_get_contents("php://stdin"), true);

 3. We wrote our output to **stdout**
-    ```node
+    ```php
-    console.log
+    echo "Hello World!\n";
     ```
 
 4. We sent **stderr** to the server logs
-    ```node
+    ```php
-    console.error
+    fwrite(STDERR, "--> this will go to stderr (server logs)\n");
+    ```
+
+5. We added PHP dependencies and enabled them using:
+    ```php
+    require 'vendor/autoload.php';
     ```
