Fix a script

I need to fix a script that mainly uses cloudflare/namecheap api and php/mysql. The script has several features : [login to view URL] creates cloudflare accounts. This part works fine. [login to view URL] imports domains from a namecheap account. This part works fine except that it can not import more than 1000 domains from namecheap (apparently an api restriction). I need a workaround. [login to view URL] adds these domains to cloudflare and change nameservers on namecheap. This part has issues because the script : .Can not proceed more than 5 domains at the same time and usually less than 5, it's totally random. I need the script to be able to proceed at least 50 domains per run. .Stops very frequently when running and doesn't finish the batch. Moreover, I always have to logout from the admin area between 2 runs; if not, it doesn't work at all. .Is supposed to choose a random cloudflare account, but it doesn't seem to use all of them.
