Works perfect!! thanks :-)

why doesn't works if I set a range ?
{"success":false,"errors":[{"code":1001,"message":"Invalid request. Configuration value was not a valid IP address"}],"messages":[],"result":null}

Is there a way to use a range ?

For others landing here, the official PHP SDK is here and its pretty great.

This block IP for all sites, is it? and how can i block IP for Specific WebSite?

I'm still looking for the same thing, did you found a solution?

I want to use your script but I am a nobe at scripting. After playing around with your script didn't reach anywhere. I want to build a script to ban Ip based on its rpm on my server and eventually removing the ban after a while say 600 seconds or 20 min. using Cloudflare and any other scan script. The idea behind is to block any DDoS attack.

where I get the block_rule_id?

where I get the block_rule_id?

cfban function returns id on succesful ban

Is it possible to batch requests without foreach loop in order to block or unblock a list of IP addresses.
The objective is to issue one HTTP request for increased performance.
Does this even exist in the CloudFlare api? How to do it with your script?
