//上表怎么做商品分类删除?删除父级分类=父级+子级
$id=$_GET['id'];
        $sql="select path from type WHERE path like '%$id%'";
        $rs=mysql_query($sql);
        $arr=mysql_fetch_assoc($rs);
       if($arr){
          $path=" and path like '%$id%'";
        }else{
            $path='';

        $where="where id={$id}{$path}";
        $sql2="delete from type $where";
        //echo $sql2;die();
        $rs=mysql_query($sql2);
        if(mysql_affected_rows()>0){
            echo '删除成功';
        }else{
            echo '删除失败';
        }
        break;
//我写的代码为什么不能删除有子级分类的商品呢?只能把子分类删完才能执行父类
//是where and的前后顺序问题吗?

比如删除女装是,需要先把休闲裤删了才行,但我想直接删完,应该怎么做呢??</code>

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: Identifying and Fixing BottlenecksPHP Performance: Identifying and Fixing BottlenecksMay 11, 2025 am 12:13 AM

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.
