/**

class DBConfig
{
public static $HOST = 'localhost';
public static $USERNAME = 'root';
public static $PASSWORD = 'root';
public static $DATABASE = 'shopping';
public static $CHARSET = 'utf8';
}
?>
/**

class DataBase{
private $connection;
/**
* 构造方法
* @access public

public function __construct(){
$CONFIG = require(dirname(__FILE__).'/DBConfig.class.php');
$this>connection = mysql_connect(DBConfig::$HOST,DBConfig::$USERNAME,DBConfig::$PASSWORD);
mysql_select_db(DBConfig::$DATABASE);
mysql_query("SET NAMES '".DBConfig::$CHARSET."'");
}
/**
* 析构方法
* @access public
*/
public function __destruct(){
mysql_close($this>connection);
}
/**
* 执行SQL查询语句
* @access private
* @param string $p_sql 查询命令
* @return array 记录集,无记录返回空数组
*/
private function query($p_sql){
$dataTemp = mysql_query($p_sql,$this>connection);
$data = array();
$dataItem = 0;
while ($rows = mysql_fetch_assoc($dataTemp)) {
$data[$dataItem] = $rows;
$dataItem++;
}
return $data;
}
/**
* 执行SQL语句
* @access public
* @param string $p_sql 需要执行的SQL,可以为INSERT,SELECT,UPDATE或DELETE
* @return 如果SQL是SELECT,返回记录集,如果SQL是INSERT,返回新记录ID,如果SQL是UPDATE或DELETE,返回所影响的行数
*/
public function execute($p_sql){
$controlr = strtoupper(substr($p_sql,0,6));
switch ($controlr) {
case 'INSERT':
mysql_query($p_sql,$this>connection);
$result = mysql_insert_id($this>connection);
break;
case 'SELECT':
$result = $this>query($p_sql,$this>connection);
break;
default:
mysql_query($p_sql,$this>connection);
$result = mysql_affected_rows($this>connection);
break;
}
return $result;
}
}
?>
调用很简单:
$sql = '.....'; // 可以是任何增删改查的语句
$db = new DataBase();
$rs = $db>execute($sql);
$db = null;
请大家多多指教!
