Overview
The sample code is intended to demonstrate how you can utilise PHP to call the operations within API-NG and extract the desired output, it is very much a cut down sample and is not intended to be used in a production environment.
...
This documentation refers to the code available at https://github.com/betfair/API-NG-sample-code/tree/master/php.
Prerequisites
To run the sample code from the command line you must have a php5 cli installed along with the curl module enabled.
Debian linux Installation
In a Debian linux distro you can use the following commands to install the pre-requisites:
sudo apt-get update
sudo apt-get install php5-cli
sudo apt-get install php5-curl
Run the scripts
JSON-RPC →
php -f jsonrpc.php <appkey> <sessiontoken>
...
php -f rescript.php <appkey> <sessiontoken>
Code Snippets
Dealing with SSL in PHP
If you have errors relating to SSL certificate issues then you must do one of the following:
...
You will need to make use of the CURLOPT_CAINFO option, and point it to the Betfair PEM formatted certificate (which you can export from your browser). The details of exporting the cert and using this option are beyond the scope of this document but can be found elsewhere online.
Calling API-NG with JSON-RPC protocol
Method and params values need to be change based on the required service operation. You can call batch multiple service operations together and correlate the responses with value of the id field.
