如何修改HTTP_USER_AGENT,把网页浏览器伪装成手机浏览器

本帖最后由 Youritumei_habataku 于 2011-11-10 17:10:45 编辑 现在PHP里判断浏览器是否是手机浏览器的方法一般是:
//php判断客户端是否为手机
$agent = $_SERVER['HTTP_USER_AGENT'];
if(strpos($agent,"NetFront") || strpos($agent,"iPhone") || strpos($agent,"MIDP-2.0") || strpos($agent,"Opera Mini") || strpos($agent,"UCWEB") || strpos($agent,"Android") || strpos($agent,"Windows CE") || strpos($agent,"SymbianOS"))
header("Location:http://bolg.malu.me/photo/wap-mini/index.php");
?>

如果是网页浏览器,他会加个代码,让他显示不出要显示的网页,我想问问PHP里面有没有可能修改自己的$_SERVER['HTTP_USER_AGENT']值,把自己伪装成一个iPhone等手机浏览器,从而在电脑上能获取这个网站的手机网页内容,我是这样获取代码的:
ob_start(); 
$ch = curl_init(); 
curl_setopt( $ch, CURLOPT_URL, $url );
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 0);
//curl_setopt( $ch, CURLOPT_POST, 1 ); 
//curl_setopt( $ch, CURLOPT_POSTFIELDS, $param ); 

//curl_exec( $ch ); 
//$retrievedhtml = ob_get_contents(); 
$retrievedhtml=curl_exec( $ch ); 
ob_end_clean(); 
curl_close( $ch );

谢谢

sorry,没仔细看问题

$user_agent = 我是手机'';

curl_setopt($ch, CURLOPT_USERAGENT, $user_agent);

Session regeneration refers to generating a new session ID and invalidating the old ID when the user performs sensitive operations in case of session fixed attacks. The implementation steps include: 1. Detect sensitive operations, 2. Generate new session ID, 3. Destroy old session ID, 4. Update user-side session information.

Reduce the use of session data and only store necessary information; 3. Use a non-blocking session processor to improve concurrency capabilities; 4. Adjust the session expiration time to balance user experience and server burden; 5. Use persistent sessions to reduce the number of data read and write times.

The security of PHP sessions can be achieved through the following measures: 1. Use session_regenerate_id() to regenerate the session ID when the user logs in or is an important operation. 2. Encrypt the transmission session ID through the HTTPS protocol. 3. Use session_save_path() to specify the secure directory to store session data and set permissions correctly.
