Check you curl version

CURLOPT_IPRESOLVE is available since curl 7.10.8

Try this sample code to test

<?php

    $version = curl_version();

// These are the bitfields that can be used 
// to check for features in the curl build
$bitfields = Array(
            'CURL_VERSION_IPV6', 
            'CURLOPT_IPRESOLVE'
            );


foreach($bitfields as $feature)
{
    echo $feature . ($version['features'] & constant($feature) ? ' matches' : ' does not match');
    echo PHP_EOL;
}
