php 類的寫法//Db.class.php

class Db {

private $_dblink;

public $result;

public function __construct($host, $user, $password, $dbname, $charset = 'utf8') {

try{

if($this->_dblink = mysql_connect($host, $user, $password)) {

if(mysql_select_db($dbname)) {

$this->query("SET NAMES " . $charset . " ;");

} else {

throw new Exception(mysql_error());

}

} else {

throw new Exception(mysql_error());

}

} catch (Exception $e) {

die($e->getMessage());

}

}

public function query($sql) {

return $this->result = mysql_query($sql);

}

public function fetch() {

return mysql_fetch_array($this->result);

}

public function fetchAll() {

$rs = array();

$rsAll = array();

while($rs = mysql_fetch_array($this->result)) {

$rsAll[] = $rs;

}

return $rsAll;

}

public function __destruct() {

mysql_close($this->_dblink);

}

}

復制PHP內容到剪貼板PHP代碼:

//test.php

$db = new Db('localhost', 'root', '', 'hent_qxoa');

$db->query("SELECT * FROM qx_user ;");

var_dump($db->fetchAll());
