  //數(shù)據(jù)庫的username

  private $name="root";

  //數(shù)據(jù)庫的password

  private $pass="";

  //數(shù)據(jù)庫名稱

  private $table="phptest";

  //編碼形式

  private $ut="utf-8";

  //構(gòu)造函數(shù)

  function __construct(){

  $this->ut=$ut;

  $this->connect();

  }

  //數(shù)據(jù)庫的鏈接

  function connect(){

  $link=mysql_connect($this->host,$this->name,$this->pass) or die ($this->error());

  mysql_select_db($this->table,$link) or die("沒該數(shù)據(jù)庫:".$this->table);

  mysql_query("SET NAMES '$this->ut'");

  }

  function query($sql, $type = '') {

  if(!($query = mysql_query($sql))) $this->show('Say:', $sql);

  return $query;

  }

  function show($message = '', $sql = '') {

  if(!$sql) echo $message;

  else echo $message.'<br>'.$sql;

  }

  function affected_rows() {

  return mysql_affected_rows();

  }

  function result($query, $row) {

  return mysql_result($query, $row);

  }

  function num_rows($query) {

  return @mysql_num_rows($query);

  }

  function num_fields($query) {

  return mysql_num_fields($query);

  }

  function free_result($query) {

  return mysql_free_result($query);

  }

  function insert_id() {

  return mysql_insert_id();

  function fetch_row($query) {

  return mysql_fetch_row($query);

  }

  function version() {

  return mysql_get_server_info();

  }

  function close() {

  return mysql_close();

  }

  //向$table表中插入值

  function fn_insert($table,$name,$value){

  $this->query("insert into $table ($name) value ($value)");

  }

  //根據(jù)$id值刪除表$table中的一條記錄

  function fn_delete($table,$id,$value){

  $this->query("delete from $table where $id=$value");

  echo "id為". $id." 的記錄被成功刪除!";

  }

  }

  $db = new ConnectionMySQL();

  $db->fn_insert('test','id,name,sex',"'','hongtenzone','M'");

  $db->fn_delete('test', 'id', 1);
