Want to use curl to get JSP page query results via PHP.

A piece of code I wrote myself (using curl) has the following results:

Specific code:

I do not know why, I test the input data is: Invoice code: fpdm1=221011270133 Invoice Serial Number: fphm1=06649746

But I use curl to return the results and manual from the official Web query to the results are not the same, seek expert guidance, thank you!

Ask the great God to teach me the same question. I also need to simulate the development of how the great God solved it. Attach My Code

$url = ' http://cx.ytjj.gov.cn:9081/ytjjvio/veh4tablevio.action?444 ';
$post _data= Array (
"Vehvio.hphm" = ' lu FZJ801 ',
"Vehvio.clsbdh" = ' 3235 ',
"Vehvio.hpzl" = "02"
);

$ch = Curl_init ();
Set the URL and the appropriate options
curl_setopt ($ch, Curlopt_url, $url);
curl_setopt ($ch, Curlopt_header, 0);
curl_setopt ($ch, Curlopt_post, 3);//set to POST mode
curl_setopt ($ch, Curlopt_returntransfer, true);
curl_setopt ($ch, Curlopt_postfields, "vehvio.hphm= fzj801&vehvio.clsbdh=3235&vehvio.hpzl=02");
curl_setopt ($ch, curlopt_encoding, "utf-8"); Here's the point.
Crawl the URL and pass it to the browser
$content = curl_exec ($ch);

Echo $content. "_";
Exit
