libeay32.dll, ssleay32.dll, php5ts.dll, php_curl.dll都拷贝到system32目录下,重启apache
PHP.ini 开启了 CURL
但是还是不行 错误提示我
Fatal error: Call to undefined function curl_multi_init() in D:\wamp\www\caiji\caiji.php on line 4
------解决方案--------------------
phpinfo();看看有没有curl,如果没有说明你根本没有开启成功(extension=php_curl.dll)
------解决方案--------------------
那你路劲没设置对,在试试~~
------解决方案--------------------
你看看你phpinfo()里面的php配置文件是你修改的那个吗?例如你把mysql模块关闭了在打开phpinfo()看看mysql模块是否开启,如果依然开启,那么说明你所用的php配置文件并不是你所修改的那个
------解决方案--------------------

php CURL 采集问题---请指教
你应该问:
curl安装不成功---请指教
重启过apache吗,杀死过php-cgi吗。
------解决方案--------------------
这个可以用。

Select 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.

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

MinGW - Minimalist GNU for Windows
This project is in the process of being migrated to osdn.net/projects/mingw, you can continue to follow us there. MinGW: A native Windows port of the GNU Compiler Collection (GCC), freely distributable import libraries and header files for building native Windows applications; includes extensions to the MSVC runtime to support C99 functionality. All MinGW software can run on 64-bit Windows platforms.

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
