在做FTP资料采集的时候，需要用到一个PHP函数ftp_connect，这个函数是建立一个新的 FTP 连接，如果成功返回一个连接标识，失败则返回 FALSE.
ftp_connect() 打开一个 FTP 连接，参数 host 为要连接的服务器。host 后面不应以斜线结尾，前面也不需要用 ftp:// 开头。可选参数port 为要连接到的 FTP 器的端口号，如果没有设置或者为0，则会使用默认的端口 21 来连接。
当我去执行我的这个程序的时候，发现报错如下：
复制代码代码如下:PHP Warning: ftp_connect(): php_network_getaddresses: getaddrinfo failed:
经常之后发现是IPtables的问题，于是我开放了FTP的默认端口，于是就能正常使用了。
遇到这种问题要首先检查自己的服务器的服务，其次就是防火墙问题了。

PHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

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.

PHP Performance: Identifying and Fixing BottlenecksMay 11, 2025 am 12:13 AM

PHP performance bottlenecks can be solved through the following steps: 1) Use Xdebug or Blackfire for performance analysis to find out the problem; 2) Optimize database queries and use caches, such as APCu; 3) Use efficient functions such as array_filter to optimize array operations; 4) Configure OPcache for bytecode cache; 5) Optimize the front-end, such as reducing HTTP requests and optimizing pictures; 6) Continuously monitor and optimize performance. Through these methods, the performance of PHP applications can be significantly improved.
