How to get website using cURL

I am not able to fetch data using cURL in php AS I can do this using curl command in terminal like below -

curl http://www.universalapplianceparts.com/search.aspx?find=w10130694

This command provide expected result in terminal.

I want same result in php using curl

Below is my php code -

$url = "http://www.universalapplianceparts.com/search.aspx?find=W10130694";
$ch = curl_init();  
    curl_setopt($ch, CURLOPT_URL,"http://www.universalapplianceparts.com/");
    curl_setopt($ch, CURLOPT_POST, true);  
    curl_setopt($ch, CURLOPT_HEADER, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $url); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
    $output = curl_exec ($ch); 
    curl_close ($ch); 
    var_dump($output);

Please let me know why I am not getting same result using php curl as I am getting in terminal.

Thanks
