CURLOPT_RESOLVE option doesn't work properly with curl php function

Question

I'm trying to execute a curl request using CURLOPT_RESOLVE but I get an error :

Warning: curl_setopt() [function.curl-setopt]: Invalid curl configuration option

This following line set the option :

curl_setopt($ch, CURLOPT_RESOLVE, 'example.com:443:127.0.0.1');

Any idea what's wrong ?

Answer 1

From the php.net doc:

An array of hostname, port, and IP address strings, each element separated by a colon. In the format: array("example.com:80:127.0.0.1")

So you can do that:

curl_setopt($ch, CURLOPT_RESOLVE, ['example.com:443:127.0.0.1']);
