在php中运行curl两次

Question

I'm trying to send email via php mail function like below but it doesn't seem to work on IE. It works on all other browsers. Below is the code. Is there a reason why???

$sent1 = mail($to, $subject, $message, $headers);
$sent2 = mail($clientTo, $clientSubject, $clientMessage, $clientHeaders);
if ($sent1 && $sent2){
                    $ch = curl_init("https://www.salesforce.com/servlet/servlet.WebToLead?encoding=UTF-8");
                    curl_setopt($ch, CURLOPT_POST, 1);
                    curl_setopt($ch, CURLOPT_POSTFIELDS, "oid=$sf_oid&first_name=$sf_first_name&last_name=$sf_last_name&company=$sf_company&phone=$sf_phone&email=$sf_email&URL=$sf_website&description=$sf_description&lead_source=$sf_leadsource");
                    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
                    curl_exec($ch);
                    $info = curl_getinfo($ch);
                    if($_SERVER['REMOTE_ADDR'] == "124.254.75.167")
                        //print_r($info);
                    curl_close($ch);

                    $ch = curl_init("http://www.rankreport.com.au/ajax/add_new_lead");
                    curl_setopt($ch, CURLOPT_POST, 1);
                    curl_setopt($ch, CURLOPT_POSTFIELDS, "lead_company_id=1&lead_business=1234&lead_first_name=asdf&lead_website=12314.com&lead_phone=1234&lead_email=test@test.com&lead_package=seo");
                    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
                    curl_exec($ch);
                    curl_close($ch);

                    echo '3';
                }

PHP has nothing to do with browser (PHP is server-side executable), so it isn't browser's problem. You have probably no $sent1 , $sent2 defined
