curl 支持SSL证书、HTTP POST、HTTP PUT 、FTP 上传，kerberos、基于HTT格式的上传、代理、cookie、用户＋口令证明、文件传送恢复、http代理通道就最常用的来说，是基于http的get和post方法。

代码实现：

1、http的get实现

复制代码 代码如下:

$ch = curl_init("http://www.jb51.net/") ;

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true) ;

curl_setopt($ch, CURLOPT_BINARYTRANSFER, true) ;

$output = curl_exec($ch) ;

$fh = fopen("out.html", 'w') ;

fwrite($fh, $output) ;

fclose($fh) ;

2、http的post实现

复制代码 代码如下:

//extract data from the post

extract($_POST) ;

//set POST variables

$url = 'http://www.jb51.net/get-post.php' ;

$fields = array(

'lname'=>urlencode($last_name) ,

'fname'=>urlencode($first_name) ,

'title'=>urlencode($title) ,

'company'=>urlencode($institution) ,

'age'=>urlencode($age) ,

'email'=>urlencode($email) ,

'phone'=>urlencode($phone)

);

//url-ify the data for the POST

foreach($fields as $key=>$value) { $fields_string .= $key.'='.$value.'&' ; }

rtrim($fields_string ,'&') ;

//open connection

$ch = curl_init() ;

//set the url, number of POST vars, POST data

curl_setopt($ch, CURLOPT_URL,$url) ;

curl_setopt($ch, CURLOPT_POST,count($fields)) ;

curl_setopt($ch, CURLOPT_POSTFIELDS,$fields_string) ;

//execute post

$result = curl_exec($ch) ;

//close connection

curl_close($ch) ;
