注意：curl函數在php中默認是不被支持的，如果需要使用curl函數我們需在改一改你的php.ini文件的設置，找到php_curl.dll去掉前面的";"就行了
例1
代碼如下 復制代碼
$uri = "http://tanteng.duapp.com/test.php";
// 參數數組
$data = array (
'name' => 'tanteng'
// 'password' => 'password'
);
$ch = curl_init ();
// print_r($ch);
curl_setopt ( $ch, CURLOPT_URL, $uri );
curl_setopt ( $ch, CURLOPT_POST, 1 );
curl_setopt ( $ch, CURLOPT_HEADER, 0 );
curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, 1 );
curl_setopt ( $ch, CURLOPT_POSTFIELDS, $data );
$return = curl_exec ( $ch );
curl_close ( $ch );
print_r($return);
接受php頁面遠程服務器：
if(isset($_POST['name'])){
if(!empty($_POST['name'])){
echo '您好，',$_POST['name'].'！';
}
}
?>

用CURL模擬POST請求抓取郵編與地址

模擬POST請求 提交數據或上傳文件 .
