韩顺平php对数据库的操作进行封装工具类

mysqlTool.php 工具类类页面

<?php
class SqlTool{
  private $conn;
  private $host="localhost";
  private $user="root";
  private $password="root";
  private $db="test";
  function SqlTool(){
   $this->conn=mysql_connect($this->host,$this->user,$this->password);
    if(!$this->conn){
		die("连接数据库".mysql_eror());
	
	}
  mysql_select_db($this->db,$this->conn);
  mysql_query("set names utf8");
  
  }
  //select dql

  pubulic function execute_dql($sql){
	  $res=mysql_query($sql,$this->conn) or die(mysql_error());
      return $res;   
  
  }
  //完成对dml的操作 insert delete update
 public funciton execute_dml($sql){
  $b=mysql_query($sql,$this->conn);
  if(!$b){
    return 0;
  }else{
    if(mysql_affacted_row($this->conn)){
	  return 1;//表示成功
	}
  
  }else{
  
     return 2;//没有影响到行数
  }
 
 }

}
?>

引入操作页面 mysqlDomo2.php

<?php
class SqlTool{
  private $conn;
  private $host="localhost";
  private $user="root";
  private $password="root";
  private $db="test";
  function SqlTool(){
   $this->conn=mysql_connect($this->host,$this->user,$this->password);
    if(!$this->conn){
		die("连接数据库".mysql_eror());
	
	}
  mysql_select_db($this->db,$this->conn);
  mysql_query("set names utf8");
  
  }
  //select dql

  pubulic function execute_dql($sql){
	  $res=mysql_query($sql,$this->conn) or die(mysql_error());
      return $res;   
  
  }
  //完成对dml的操作 insert delete update
 public funciton execute_dml($sql){
  $b=mysql_query($sql,$this->conn);
  if(!$b){
    return 0;
  }else{
    if(mysql_affacted_row($this->conn)){
	  return 1;//表示成功
	}
  
  }else{
  
     return 2;//没有影响到行数
  }
 
 }

}
