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 this section, MongoDB is used.

Prerequisites

• Docker is installed. For more information, see the "Install Docker" section of the Install Serverless Devs and Docker topic.

• A function whose runtime is PHP is created. For more information, see the "Create a function" section of the Manage functions topic.

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:

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

   Note

   If your computer runs Windows, you can replace $(pwd) with a specific absolute directory.

2. Install the MongoDB extension and copy and paste the mongodb.so file 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 file extension:

      find /usr -name "mongodb.so"

   3. Run the following command to copy the extension file to the /code directory (that is, copy and paste the file to a directory on your computer):

      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 Services & Functions.

4. In the top navigation bar, select a region. On the Services page, click the desired service.

5. On the page of a service that you want to manage, click the desired function. On the Code tab, create a folder named extension, and the folder is in the same directory as the handler file of the function.

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
