"Use of undefined constant CURLOPT_PROTOCOLS and CURLPROTO_HTTP" but it works?

Question

Hi on our dev environment we have show all errors, warnings and notices. I'm getting this:

Notice: Use of undefined constant CURLOPT_PROTOCOLS - assumed 'CURLOPT_PROTOCOLS' in C:\notion\implementation\development\asterix\library\ExternalLibs\panda.php on line 69

Notice: Use of undefined constant CURLPROTO_HTTP - assumed 'CURLPROTO_HTTP' in C:\notion\implementation\development\asterix\library\ExternalLibs\panda.php on line 69

The code on line 69:

    curl_setopt($curl, CURLOPT_PROTOCOLS, CURLPROTO_HTTP);

But the CURL code works, it goes off to the other server and retrieves whats necessary. What do these notices mean?

Thanks very much.

This seemed to be a bug in PHP 5.2.9: #48390

According to the documentation, the option "CURLOPT_PROTOCOLS" is available as of cURL 7.19.4, but PHP is throwing a notice: "Use of undefined constant CURLOPT_PROTOCOLS - assumed 'CURLOPT_PROTOCOLS'"

Also all the "CURLPROTO_*" constants are not available:

Use of undefined constant CURLPROTO_HTTPS - assumed 'CURLPROTO_HTTPS'

I don't know what this setting does exactly, but I would assume in your case, the setting is not applied at all, because curl can't interpret the string "CURLPROTO_HTTP". If it works either way, it may be safer to comment it out, because with the next upgrade, the constants are likely to be there.
