通过利用cURL

这是一个例子

<?php
// create a new cURL resource
$ch = curl_init();

// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, "http://judis.nic.in/supremecourt/DateQry.aspx");
curl_setopt($ch, CURLOPT_HEADER, 0);

// say if your URL has any POST params
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "name=John");


// grab URL and pass it to the browser
$response=curl_exec($ch);

//Display your response
echo $response;

// close cURL resource, and free up system resources
curl_close($ch);
?>

编辑：

像这样连接字段

//Since you are using multiple fields .. do like this 
$postFields="button=Submit&ddlday=01&ddlday2=31&ddlmonth1=01&ddlmonth2=01&ddlreport=A&ddlyear1=2013&ddlyear2=2013";
        curl_setopt($ch, CURLOPT_POSTFIELDS, $postFields);
