Default cURL option values

Question

I was refactoring my cURL class today and thought about looking at default values of cURL FLAGS.
Could anyone tell me where I might find or how could I output them?

PS: If it's possible at all.

Answer 1

This will display the "CURL*" constant names and their values:

foreach (get_defined_constants() as $name => $val) {
    if (strpos($name, 'CURL') === 0) {
        echo $name . ' => ' . $val . "\n";
    }
}

For just the curl option values, change 'CURL' to 'CURLOPT_', of course.

(If you're thinking of using the integer values instead of the constant names in your script, you shouldn't.)
