Configure a PHP/cURL Application to Use Fiddler

Updated on Nov 6, 2025

To configure a PHP/cURL application to send web traffic to Fiddler Classic, add this line of code before the application sends requests, where $ch is the handle returned by curl_init():

bash
curl_setopt($ch, CURLOPT_PROXY, '127.0.0.1:8888');

Or, enter this command from the command line:

bash
curl --proxy 127.0.0.1:8888
