php的curl实现get和post
            
            
                    类似于dreamhost这类主机服务商,是显示fopen的使用的。使用php的curl可以实现支持FTP、FTPS、HTTP HTPPS SCP SFTP TFTP TELNET DICT FILE和LDAP。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
[php]
function curl_get($url){
    $ch = curl_init();
    curl_setopt($ch,CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_BINARYTRANSFER, true);
    curl_setopt($ch,CURLOPT_HEADER, 0);
//    $ret['all'] = curl_getinfo($ch);
//    var_dump($ret);
    $output = curl_exec($ch);
    curl_close($ch);
    return $output;
}
[/php]
2、http的post实现
[php]
//extract data from the post
function curl_post($url,$post){
    //set POST variables
    $fields = array(
            'last_name'=>urlencode($post['last_name']) ,
            'first_name'=>urlencode($post['first_name']) ,
            'title'=>urlencode($post['title']) ,
            'company'=>urlencode($post['institution']) ,
            'age'=>urlencode($post['age']) ,
            'email'=>urlencode($post['email']) ,
            'phone'=>urlencode($post['phone'])
        );
    //url-ify the data for the POST
    $fields_string = '';
    foreach($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) ;
    //$ret['all'] = curl_getinfo($ch);//高度信息
    //var_dump($ret);
    //close connection
    curl_close($ch);
    return $result;
}
[/php]
