关于dsn的问题
最近在codeigniter中使用dsn进行数据库连接,但是不管端口号改成什么总是能够连接成功,而修改用户名,密码或ip地址的话就会出现连接失败的问题,下面是我的代码

PHP code
<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->    function get_remote_dblist($ip, $port, $user, $pwd) {        $dsn = "mysql://$user:$pwd@$ip:$port";        $newDB = $this->load->database ( $dsn , TRUE );return $newDB->version();}

烦请各位前辈指点下

------解决方案--------------------
CI的官方文档中并未提及DSN中主机名可以附加端口号。有一个折衷的方法你可以试试
PHP code
$dsn = "mysql://{$user}:{$pwd}@{$ip}/?port={$port}";<div class="clear">
                 
              
              
        
            </div>

PHP Dependency Injection: Improve Code TestabilityPHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

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.
