一开始安装php,但是后来在网上摘抄了一些 yum install php-pdo php-zip 之类的,结果现在php无法卸载也无法重装
使用yum install php提示已经安装了。但是 php -v 却提示不存在。
整个过程:

回复讨论(解决方案)
把php安装目录下的bin指向 ln xx /usr/bin试试
可以试试这样卸载:
rpm -qa | grep phprpm -e [上面输出的包]

yum 安装的你就 yum 卸载 然后自己编译一个 最后 php 指令做个软连接过去

依赖注入(DI)通过显式传递依赖关系,显著提升了PHP代码的可测试性。1)DI解耦类与具体实现,使测试和维护更灵活。2)三种类型中,构造函数注入明确表达依赖,保持状态一致。3)使用DI容器管理复杂依赖,提升代码质量和开发效率。

PHP性能瓶颈可以通过以下步骤解决:1)使用Xdebug或Blackfire进行性能分析,找出问题所在;2)优化数据库查询并使用缓存,如APCu;3)使用array_filter等高效函数优化数组操作;4)配置OPcache进行字节码缓存;5)优化前端,如减少HTTP请求和优化图片;6)持续监控和优化性能。通过这些方法,可以显著提升PHP应用的性能。
