[SalesForce] SSL certificate problem: unable to get local issuer certificate, curl_errno 60

Can you post your curl command?

Also are you passing the security token?

Please see this. Have you passed the username param? Error using Session Id auth with cURL following REST documentation

If you are using Mac or Linux, see this: http://www.salesforce.com/us/developer/docs/api_rest/Content/intro_curl.htm

A few things that I noticed:

1. You posted your password and security token; I really hope those are dummy values.
2. The script is creating Contacts without assigning them to Accounts, which means they're orphaned. Orphaned Contacts can be harder to find; in production, you generally always want your Contacts tied to Accounts.
3. The script provides output with the ids of the new records. You can navigate directly to these records by putting the id in the URL. Ids of Contacts will always being with 003.

Example:

I created the Contact John Smith, with id 003P000000fJqfv. I can then navigate to https://[instance].salesforce.com/003P000000fJqfv to view John's record.

Your script provides this information (it's $record->Id):

echo "Results of query '$query'<br/><br/>\n";
                foreach ($response->records as $record) {
                    echo $record->Id.": ".$record->FirstName." "
                   .$record->LastName." ".$record->Phone."<br/>\n";
                }
