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]
