PHP-Namecheap-Script-for-Letsencrypt-Challenge

This PHP command line script can be used to add a Letsencrypt "DNS-01 challenge" record to your Namecheap DNS. Namcheap API is used to add such TXT record. It can handle multiple domains with different Namcheap-APIKEYs. The script expects only two input parameters provided by Letsencrypt during the SSL validation process, an ACME-HOST-String and a TOKEN-String.
