PHP扩展CURL的用法详解

$curl = curl_init(‘www.jb51.net')

$user = "admin";
$pass = "admin";
$curlPost = "user=$user&pass=$pass";
$ch = curl_init(); //初始化一个CURL对象
curl_setopt($ch, CURLOPT_URL, "http://localhost/edu/login.php");
//设置你所需要抓取的URL
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);
//设置curl参数，要求结果是否输出到屏幕上，为true的时候是不返回到网页中
假设上面的0换成1的话，那么接下来的$data就需要echo一下。
curl_setopt($ch, CURLOPT_POST, 1);
//post提交
curl_setopt($ch, CURLOPT_POSTFIELDS, $curlPost);
$data = curl_exec($ch);
//运行curl,请求网页。
curl_close($ch);
[/code]

//初始化一个 cURL 对象
$curl = curl_init();
//设置你需要抓取的URL
curl_setopt($curl, CURLOPT_URL, " http://www.baidu.com ");
//设置cURL 参数，要求结果保存到字符串中还是输出到屏幕上。
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 0);
//运行cURL，请求网页
$data = curl_exec($curl);
//关闭URL请求
curl_close($curl);
$user = "admin";
$pass = "admin100";
$curlPost = "user=$user&pass=$pass";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, " http://localhost/curl/login.php ");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $curlPost);
$data = curl_exec($ch);
curl_close($ch);
?>
if($_POST['user']=="admin"){
 echo "";
}else{
 echo "";
}
//print_r($_POST);
?>
