php multi-curl util

motivation: - simplify code by using a common method for making single- or multi-curl requests

usage: - create a file, e.g. “curl.inc”, on your server and copy the code below w/ comment “multi curl util” into it - create another file, e.g. “curl_test.php”, on your server and copy the code below w/ comment “test” into it - browse to yourdomain.com/yourpath/curl_test.php - comment-out or -in the various examples in the test code to see some common use cases

notes: - only get and post are supported - if you see a way to improve the code, please leave a comment.
