}
}
curl_close($curl);
return $result;
}

Answer 1

I've copy-pasted your code to a file (test.php) on my computer, surrounded it with a
<?php .. ?>
block, and added a call like this after the function:
$res=callAPI('GET', 'http://myserver/', '');
echo $res;
Then started the script in command line by php test.php, and got the expected result (the index.html file of my server).
So whatever you're doing works. Try testing it in command line first to see if necessary modules are installed/enabled. If it works that way, try to fix your webserver's config files. If you need more help, please add some information about your system (webserver, version, OS, and anything relevant). Sysadmins tend to disable certain features (including curl) on shared hosting, maybe your default configuration is based on that.

I will recommend you check your firewall and to check if the domain what ip is resolving.
telnet domain 80
telnet ipserver 80
