Baseregular

$url ="xxxxxxxxxxxxxxxxxxxxxx
,111111111111:
xxxxxxxxxxxxxxxxxxx";
    $preg = "/^,([0-9]+):$/im";
    preg_match_all($preg,$url,$a);
    print_r($a);
?>

请问为何此例子在Window下无法正常匹配，而在Linux下正常匹配
是因为换行符不同 \n\r 和 \n 嘛？PHP正则基于Linux？
还是其他原因

回复讨论(解决方案)

你的理解是正确的，写成这样就通用了
$preg = "/^,([0-9]+):\s*$/im";

其实 : 就已经可以很好地判断结束了，不需要行尾 $
$preg = "/^,([0-9]+):/im";

How can you prevent session fixation attacks?Apr 28, 2025 am 12:25 AM

Effective methods to prevent session fixed attacks include: 1. Regenerate the session ID after the user logs in; 2. Use a secure session ID generation algorithm; 3. Implement the session timeout mechanism; 4. Encrypt session data using HTTPS. These measures can ensure that the application is indestructible when facing session fixed attacks.

How do you implement sessionless authentication?Apr 28, 2025 am 12:24 AM

Implementing session-free authentication can be achieved by using JSONWebTokens (JWT), a token-based authentication system where all necessary information is stored in the token without server-side session storage. 1) Use JWT to generate and verify tokens, 2) Ensure that HTTPS is used to prevent tokens from being intercepted, 3) Securely store tokens on the client side, 4) Verify tokens on the server side to prevent tampering, 5) Implement token revocation mechanisms, such as using short-term access tokens and long-term refresh tokens.

What are some common security risks associated with PHP sessions?Apr 28, 2025 am 12:24 AM

The security risks of PHP sessions mainly include session hijacking, session fixation, session prediction and session poisoning. 1. Session hijacking can be prevented by using HTTPS and protecting cookies. 2. Session fixation can be avoided by regenerating the session ID before the user logs in. 3. Session prediction needs to ensure the randomness and unpredictability of session IDs. 4. Session poisoning can be prevented by verifying and filtering session data.
