Twilio Client Quickstart for PHP

This application should give you a ready-made starting point for writing your own voice apps with Twilio Client. Before we begin, we need to collect all the config values we need to run the application:

Config Value Description
Account SID Your primary Twilio account identifier - find this in the console here.
Auth Token Used to authenticate - just like the above, you'll find this here.
TwiML App SID The TwiML application with a voice URL configured to access your server running this app - create one in the console here. Also, you will need to configure the Voice "REQUEST URL" on the TwiML app once you've got your server up and running.
Twilio Phone # A Twilio phone number in E.164 format - you can get one here

Setting Up The PHP Application

  1. Create a configuration file for your application:

    cp config.example.php config.php
  2. Edit config.php with the four configuration parameters we gathered from above.

  3. Next, we'll need to install the Twilio Helper library via Composer.

    composer install
  4. Run the application using the php -S command.

    php -S localhost:8000

    Alternately, you could simply place the contents of this project directly in the webroot of your server and visit index.html.

  5. Your application should now be running at http://localhost:8000.

  6. Download and install ngrok

  7. Run ngrok:

    ngrok http 8000
  8. When ngrok starts up, it will assign a unique URL to your tunnel. It might be something like Take note of this.

  9. Configure your TwiML app's Voice "REQUEST URL" to be your ngrok URL plus /voice.php. For example:

You should now be ready to rock! Make some phone calls. Open it on another device and call yourself. Note that Twilio Client requires WebRTC enabled browsers, so Edge and Internet Explorer will not work for testing. We'd recommend Google Chrome or Mozilla Firefox instead.
