mysql中用bigint字段储存手机10位号码,居然被截短。
我怎么每次用BIGINT 字段储存手机号码 的时候 。 不管,打什么11位的号码,都只显示4294967295
------解决方案--------------------
echo pow(2, 32); //4294967296
那是因为你在 php 中没有把手机号码当做字符串处理
------解决方案--------------------
PHP 的“整数值”类型不支持 11 位十进制数(这里说的是 32 位操作系统上)。
超过范围的“整数值”会被 PHP 转换成“浮点数”。
你遇到的问题,有可能是你使用了某种数据库接口程序,对这种情况做了特殊处理。总之你要是能看到最终执行的 INSERT INTO ... 语句,就都清楚了。

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.
