HomeBackend DevelopmentPHP Tutorial十天学会php之第三天_php基础

  学习目的:学会构建数据库

  在ASP中,如果是ACCESS数据库你可以直接打开ACCESS来编辑MDB文件,如果是SQL SERVER你可以打开企业管理器来编辑SQL SERVER数据库,但是在PHP中,MY SQL的命令行编辑可能会令初学者感到很麻烦,不要紧,你下载一个PHPMYADMIN安装一下,以后建立编辑数据库可以靠它了。

  下面说一下它的使用。
  进入了phpmyadmin后,我们首先需要建立一个数据库,Language (*) 这里选择中文简体,然后在左边的 创建一个新的数据库 这里填写数据库名字,点击创建即可。

  然后在左边下拉菜单中选择那个已经创建的数据库。在下面的

  在数据库 shop 中创建一个新表 :
  名字 :
  字段数 :

  中填写表名字和大致你认为的字段数(不够或者多了都不要紧,以后可以再添加或者缺省),按执行。
  然后就可以开始建立表了。
  第一栏是字段的名字;第二栏选择字段类型:
  我们常用的是以下几个:
  1)VARCHAR,文本类型
  2)INT,整数类型
  3)FLOAT,浮点数类型
  4)DATE,日期型
  5)大家或许会问,自动添加的ID在哪里?这个只要选择INT类型,在后面的额外中选择 auto_increment 就可以了。

  建立了表以后,可以在左边看到你建立的表,点击以后,你可以:
  1)按右边的结构:查看修改表结构
  2)按右边的浏览:查看表中的数据
  3)按右边的SQL:运行SQL语句
  4)按右边的插入:插入一行记录
  5)按右边的清空:删除表中所有记录
  6)按右边的删除:删除表

  还有一个很重要的功能就是导入和导出,当我们本机做好了程序和数据库的时候,需要在服务器上也有一个本地镜像,如果是ASP的ACCESS简单了,直接上传MDB文件即可,如果是SQL SERVER也可以连接远端服务器进行导入。那么MY SQL中你可以导出所有的SQL语句,到了远端服务器的PHPMYADMIN上,创建数据库后按SQL,粘帖你刚才复制下来的所有本级生成的SQL语句即可。

  今天就说到这里,明天继续说数据库操作。

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.
