大家能说说php中那些函数存在着漏洞吗？
可能单个函数不怎么厉害，但组合起来就可以实现一些厉害的事情。
passthru
exec
system
chroot
scandir
chgrp
chown
shell_exec
proc_open
proc_get_status
ini_alter
ini_alter
ini_restore
dl
pfsockopen
openlog
syslog
readlink
symlink
popepassthru
stream_socket_server
fsocket
fsockopen
一些系统级的函数危险性比较高。
其实这个就和搭积木一个原理，每块积木本身是没有什么危险性的，但是你把它们搭在一起搭不好是很容易坍塌的。

Dependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AMYou should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AMSelect DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
