Homephp教程php手册如何在十天学内会php之第九天

学习目的:注意事项
  
  因为我是先学ASP的,所以再做PHP的时候会发现很多地方需要适应。
  
  1、注意不要漏了分号
  2、注意不要漏了变量前的$
  3、使用SESSION的时候注意不要遗漏session_start();
  
  如果发生错误的时候,可以采用以下方法:
  1、如果是SQL语句出错,就注释了然后输出SQL语句,注意也要注释调后续的执行SQL语句
  2、如果是变量为空,大多是没有传递到位,输出变量检查一下,检查一下表单的id和name
  3、如果是数据库连接出错,检查是否正确打开MY SQL和是否遗漏了连接语句
  4、注意缩进,排除括号不区配的错误
  
    
  好了,今天说到这里,明天说一下如果用PHP上传文件和发邮件。
