+# Wipe an Appwrite collection
+
+A PHP Cloud Function that wipes out all the documents inside a collection.
+
+_Example input:_
+
+```json
+{
+    "databaseId": "stage",
+    "collectionId": "profiles"
+}
+```
+
+_Example output (success):_
+
+```json
+{
+    "success": true,
+    "sum": 2
+}
+```
+
+_Example output (failure):_
+
+```json
+{
+    "success": false,
+    "message": "Collection not found."
+}
+```
+
+## 📝 Environment Variables
+
+List of environment variables used by this cloud function:
+
+- **APPWRITE_FUNCTION_ENDPOINT** - Endpoint of your Appwrite server
+- **APPWRITE_FUNCTION_API_KEY** - Appwrite API Key
+- **APPWRITE_FUNCTION_PROJECT_ID** - Appwrite project ID. If running on Appwrite, this variable is provided automatically.
+
+## 🚀 Deployment
+
+1. Clone this repository, and enter this function folder:
+
+```
+$ git clone https://github.com/open-runtimes/examples.git && cd examples
+$ cd php/wipe_appwrite_collection
+```
+
+2. Enter this function folder and build the code:
+```
+docker run --rm --interactive --tty --volume $PWD:/usr/code openruntimes/php:v2-8.1 sh /usr/local/src/build.sh
+```
+As a result, a `code.tar.gz` file will be generated.
+
+3. Start the Open Runtime:
+```
+docker run -p 3000:3000 -e INTERNAL_RUNTIME_KEY=secret-key -e INTERNAL_RUNTIME_ENTRYPOINT=index.php --rm --interactive --tty --volume $PWD/code.tar.gz:/tmp/code.tar.gz:ro openruntimes/php:v2-8.1 sh /usr/local/src/start.sh
+```
+
+Your function is now listening on port `3000`, and you can execute it by sending `POST` request with appropriate authorization headers. To learn more about runtime, you can visit PHP runtime [README](https://github.com/open-runtimes/open-runtimes/tree/main/runtimes/php-8.1).
+
+4. Execute function:
+
+```
+curl http://localhost:3000/ -d '{"variables":{"APPWRITE_FUNCTION_ENDPOINT":"YOUR_ENDPOINT","APPWRITE_FUNCTION_PROJECT_ID":"YOUR_PROJECT_ID","APPWRITE_FUNCTION_API_KEY":"YOUR_API_KEY"},"payload":"{\"databaseId\":\"stage\",\"collectionId\":\"profiles\"}"}' -H "X-Internal-Challenge: secret-key" -H "Content-Type: application/json"
+```
+
+## 🚀 Deployment using Appwrite
+
+1. Clone this repository, and enter this function folder:
+```
+$ git clone https://github.com/open-runtimes/examples.git && cd examples
+$ cd php/wipe_appwrite_collection
+```
+
+2. Enter this function folder and build the code:
+```
+docker run --rm --interactive --tty --volume $PWD:/usr/code openruntimes/php:v2-8.1 sh /usr/local/src/build.sh
+```
+As a result, a `code.tar.gz` file will be generated.
+
+3. Add a new function to appwrite server. Upload the code.tar.gz file manually. Set index.php as entrypoint.
+
+4. Execute the function. Pass collection ID and database ID as shown in example input and execute the function.
+
+
+## 📝 Notes
+ - This function is designed for use with Appwrite Cloud Functions. You can learn more about it in [Appwrite docs](https://appwrite.io/docs/functions).
+ - This example is compatible with PHP 8.1. Other versions may work but are not guaranteed to work as they haven't been tested.
