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

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 the PHP runtime, perform the following steps. MongoDB is used in this example.


  • Docker is installed. For more information, see Install Docker.
  • A function whose runtime environment is PHP is created. For more information, see Create a function.


  1. Run the following command in a project directory to start the image of the PHP runtime environment and mount the current directory to the /code directory of a container:
    docker run -v $(pwd):/code -it --entrypoint=""  bash
    Note If your computer runs Windows, you can change $(pwd) to a specific absolute directory.
  2. Install the MongoDB extension and copy the 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 extension:
      find /usr -name ""
    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/ /code
    4. Run the following command to exit the container:
    5. Run the following command to check whether the file exists. If the file exists, the .so file is stored on your computer.
      Expected output:
  3. Log on to the Function Compute console.
  4. In the left-side navigation pane, click Services and Functions.
  5. In the top navigation bar, select a region.
  6. On the Services page, click the desired service.
  7. On the Functions page of the specified service, click the specified function. On the Code tab, 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 the bootstrap file.
  8. Add the file to the extension folder, and create the mongodb.ini file in the extension folder.
  9. Edit the mongodb.ini file.
    Add the following content to the mongodb.ini file and save the file:
If you want to install other custom extensions, download the following files based on your business requirements:
