网站被黑了咋办？
如题，主页不可以打开，其它一些网页可以打开，开始有一些非法链接注入了网页，到现在网页都打不开了。
回复讨论(解决方案)
应该是篡改了主页，检查下服务器。
同问，有没有一些简单的防止网站被黑的思路或者方法呢(php背景)？
检查一下你的网站目录下有不有一些奇怪的php文件吧先。
找把所有传递过来的参数做过滤，然后找漏洞
当然首先是保证服务器没有明显的漏洞
权限别给高了，755就可以运行的不要给777

Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1?
Apr 17, 2025 am 12:06 AM
In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.
How does PHP type hinting work, including scalar types, return types, union types, and nullable types?
Apr 17, 2025 am 12:25 AM
PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
