PHP code to Purge Cloudflare Cache

purge_cf.php

<?php
// Replace EMAIL/API_KEY/ZONE_ID with your details. 
// Zone ID is on the dashboard for the domain in the bottom right.
// Api keys are generated from the account settings. You must give cache purge permissions
// Place this script on your webserver and point a Github Webhook at it, and you'll clear 
// the Cloudflare cache every time you do a push to GH.

$zoneId = "xxx";
$apiKey = "xxx";
$email = "xxx";

// optional URL for individual URL purge
$file = 'https://example.com/style.css';

try {
    $head = [];
    $head[] = 'Content-Type: application/json';
    $head[] = "X-Auth-Email: $email";
    $head[] = "X-Auth-Key: $apiKey";
    $head[] = 'cache-control: no-cache';

    $url = "https://api.cloudflare.com/client/v4/zones/$zoneId/purge_cache";
    // You can also purge files like:
    //$purge = ['files' => [$file];

    $purge = ['purge_everything' => true];
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "DELETE");
    curl_setopt($ch, CURLOPT_HTTPHEADER, $head);
    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($purge));
    $result = curl_exec($ch);
    $httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
    curl_close($ch);
} catch (Exception $e) {
    print($e);
}

great script, but can you purge cache to multiple domains (zones) ? I have 100+ domains and I wanna purge cache for all zones for current account.
Thanks!

Just add a loop and use a different zone-id to purge the caches you want to use.

Personally I am doing these kind of things based on information coming from a database. This way it is easy to log the results, and keep track when the purges were processed. If you are interested in such scripts you may visit : https://toolbox.tomdings.com/

Thank you for asking and enjoy your day!

This is the updated code in 2023.

$zoneId = "xxx";
$apiKey = "xxx";
$email = "xxx;
try {
    $head = [];
    $head[] = 'Content-Type: application/json';
    $head[] = "X-Auth-Email: $email";
    $head[] = "X-Auth-Key: $apiKey";
    $head[] = 'cache-control: no-cache';

    $url = "https://api.cloudflare.com/client/v4/zones/$zoneId/purge_cache";
    // You can also purge files like:
    $purge = ['files' => ['https://xxx.com/xxx]];
    //$purge = ['purge_everything' => true];
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "DELETE");
    curl_setopt($ch, CURLOPT_HTTPHEADER, $head);
    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($purge));
    $result = curl_exec($ch);
    $httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
    curl_close($ch);
} catch (Exception $e) {
    print($e);
}

I updated the code in the gist Tapan-thapa! Thanks for posting. Lemme know if I missed anything.
