有时候我们再运行php程序时,会出现
Allowed memory size of 8388608 bytes exhausted (tried to allocate 1298358 bytes)
出现该错误的原因:在确保不是程序产生的原因(例如死循环),是由于php页面消耗的最大内存默认是为 8M (在PHP的ini件里可以看到) ,
如果文件太大 或图片太大 在读取的时候 会发生上述错误。
解决办法:
1.修改 php.ini将memory_limit由 8M 改成 16M(或更大),重启apache服务
2.在PHP 文件中 加入 ini_set(‘memory_limit',‘**M');注意:为了系统的其它资源的正常使用 请您不要将 memory_limit设置太大,其中-1为不限
3.修改.htaccess 文档(前提是该目录支持.htaccess)在文档中新增一句:php_value memory_limit 16M(或更大)

You 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.

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.
