Built-in extension example

The following sample code uses json to parse a JSON string and return the parsed content to stdout:

<?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

To install a non-built-in extension for a PHP runtime, perform the following steps. In the following example, MongoDB is installed.

Prerequisites

• Docker is installed. For more information, see Step 2: Configure Serverless Devs.

• A function whose runtime is PHP is created. For more information, see Create an event function.

Procedure

1. Run the following command in a project directory to start the image of the PHP runtime and mount the current directory to the /code directory of the container:

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

   Note

   If your computer runs a Windows operating system, you can change $(pwd) to a specific absolute directory.

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

   1. Run the following command to install the MongoDB extension in the container:

      pecl install mongodb

   2. Run the following command to find the ZIP extension:

      find /usr -name "mongodb.so"

   3. Run the following command to copy the extension file to the /code directory:

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

   4. Run the following command to exit the container:

      exit

   5. Run the following command to check whether the mongodb.so file exists. If the file exists, the .so file is stored on your computer.

      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 of the function, click the Code tab. Then, create the extension folder in the directory in which the handler files are stored.

   Note

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

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

7. Edit the mongodb.ini file.

   Add the following content to the mongodb.ini file and save the file:

   extension=/code/extension/mongodb.so
