Illegal mix of collations (utf8_unicode_ci,IMPLICIT) and (gbk_chinese_ci,COERCIB
我的php文件设置的是utf8的，数据库连接过程也都是utf8。数据库用的校对编码及字符编码是utf8_unicode_ci。但是我在执行查询句 $sql = "select * from commodity where commodity_name like '%$newstr[0]%' or Sale_Address like '%$newstr[0]%' order by id desc ";时出现了Illegal mix of collations (utf8_unicode_ci,IMPLICIT) and (gbk_chinese_ci,COERCIBLE) for operation 'like'的报错。请问谁能猜到怎么回事，该怎么解决？

------解决方案--------------------
肯能输入字符是全角或半角的问题
------解决方案--------------------
$newstr[0]里地内容改变，造成编码不统一，你可以找一种出错的情况，把$sql输出看一下

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.
