mysql 遇到特殊字符,造成了数据不全
我是把数组序列化之后存入数据库的某个字段,但是数组中有些数据的值带有特殊字符,如图:
保存在数据库之后就成这样子了
类似这样的特殊字符还有很多的;
丢失了一部分数据,哪位哥哥遇到过这种情况吗?请赐教。

header('Content-type: text/html;charset=utf-8');<br />$s = '6b6Z5Y2O8K+gpQ==';<br />echo $t = base64_decode($s), PHP_EOL;<br />echo bin2hex($t);龙华
------解决思路----------------------
把不是utf8的字符過濾就可以了。

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 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.
