Built-in extension example

This example uses json to parse a JSON string and print the result:

<?php
function handler($event, $context) {
    var_dump(json_decode('{"a":123, "b":true, "c":"abcd", "d":{"a":123}}', true));
    return "bye";
}         

Install non-built-in PHP extensions

The following steps show how to install a non-built-in PHP extension, using MongoDB as an example.

Prerequisites

• Docker is installed. For more information about the procedure, see Step 2: Configure your AccessKey pair.

• A function that runs in a PHP runtime is created. For more information about the procedure, see Create an event-triggered function.

Procedure

1. Run the following command from your project directory to start the PHP runtime container and mount the current directory to /code:

   sudo docker run -v $(pwd):/code -it --entrypoint=""  registry.cn-beijing.aliyuncs.com/aliyunfc/runtime-php7.2:latest  bash

   Note

   On Windows, replace $(pwd) with an absolute directory path.

2. Install the MongoDB extension and copy mongodb.so to the /code directory.

   1. Install the MongoDB extension:

      pecl install mongodb

   2. Find the MongoDB extension file:

      find /usr -name "mongodb.so"

   3. Copy the extension file to /code:

      cp /usr/local/lib/php/extensions/no-debug-non-zts-20170718/mongodb.so /code

   4. Exit the container:

      exit

   5. Verify that mongodb.so exists in your local directory.

      ls

      Expected output:

      mongodb.so

3. Log on to the Function Compute console. In the left-side navigation pane, click Functions.

4. In the top navigation bar, select a region. On the Functions page, click the function that you want to manage.

5. On the function details page, click the Code tab and create an extension folder in the handler file directory.

   Note

   The extension folder must be at the same level as bootstrap.

6. Add mongodb.so to the extension folder and create mongodb.ini in the extension folder.

7. Edit the mongodb.ini file.

   Add the following line to mongodb.ini:

   extension=/code/extension/mongodb.so
