平時寫專案的時候經常會碰到操作資料庫，每次操作資料庫的時候最麻煩的就是要寫一個表對映的類，根據規律總結寫了一個自動生成的小demo：

<?php
// 資料庫配置引數
$db_config = array(
    'host' => '127.0.0.1',
    'port' => 3306,
    'username' => 'root',
    'password' => '',
    'dbname' => 'joe_db',
    'charset' => 'utf8'
);

$tablePre = 'joe_'; // 表字首
$tableName
 
 = 'users'; // 表名
$res = linkdb($db_config, $tablePre . $tableName);

$className = $tableName . 'Dmodel';
$fileName = $tableName . '.dm.class.php';
$annStr = addAnnotation($fileName, $tableName, '使用者session表');
$classStr = readTableStr($res, $className,$annStr);

// 寫入檔案
$file = fopen($fileName, "w+");
fwrite($file
 
, $classStr);
fclose($file);

/**
 * 根據表結構初始化表物件
 *
 * @param unknown $res            
 * @param unknown $className            
 * @return string
 */
function readTableStr($res, $className, $annStr='')
{
    $result = '<?php ' . "\n";
    $result .= $annStr;
    $result .= "class $className \n{";

    // 變數
 

    foreach ($res as $v) {
        $result .= "\n" . 'private $_' . strtolower($v['Field']) . ";//" . $v['Comment'] . $v['Type'];
    }

    $result .= "\n";

    // get set
    foreach ($res as $v) {
        $result .= "\n public function set" . $v['Field'] . '($_' . strtolower($v['Field']) . "){";
        $result .= "\n" . ' $this->_' . strtolower($v['Field']) . '=$_' . strtolower($v['Field']) . ";";
        $result .= "\n }";

        $result .= "\n public function get" . $v['Field'] . '(){';
        $result .= "\n" . ' return $this->_' . strtolower($v['Field']) . ";";
        $result .= "\n }";

        $result .= "\n";
    }

    $result .= " \n }";
    $result .= " \n ?>";

    return $result;
}

/**

 */
function addAnnotation($fileName, $fun, $des)
{
    $annStr =  "\n/**";
    $annStr .= "\n* 檔名：" . $fileName;
    $annStr .= "\n* 功能：    模型層-表-" . $fun;
    $annStr .= "\n* 描述：    " . $des;
    $annStr .= "\n* 日期：    " . date('y-m-d', time());
    $annStr .= "\n* 版權：    Copyright © 2016 github.com/JoeXiong All Rights Reserved";
    $annStr .= "\n* @author JoeXiong";
    $annStr .= "\n*/";
    return $annStr;
}

/**

 *
 * @param unknown $array
 *            資料庫連線引數

 *            表名
 */
function linkdb($array, $tableName)
{
    $mysql_server_name = $array['host']; // 改成自己的mysql資料庫伺服器
    $mysql_username = $array['username']; // 改成自己的mysql資料庫使用者名稱
    $mysql_password = $array['password']; // 改成自己的mysql資料庫密碼
    $mysql_database = $array['dbname']; // 改成自己的mysql資料庫名
    $conn = mysql_connect($mysql_server_name, $mysql_username, $mysql_password) or die("error connecting"); // 連線資料庫
    mysql_query("set names " . $array['charset']); // 資料庫輸出編碼
    mysql_select_db($mysql_database); // 開啟資料庫

    $sql = "SHOW FULL COLUMNS FROM $tableName";
    $res = mysql_query($sql);
    $res = dataTable($res);

    return $res;
}

/**
 * 返回到表集合
 *
 * @param query $query            
 * @return array
 */
function dataTable($query)
{
    if ($query) {
        $ListTable = array();
        while ($rows = mysql_fetch_array($query, MYSQL_ASSOC)) {
            array_push($ListTable, $rows);
        }
        return $ListTable;
    } else {
        return 0;
    }
}

/**
 * 除錯函式
 *
 * @param unknown $msg            
 */
function show_bug($msg)
{
    echo '<pre>';
    var_dump($msg);
    echo '</pre>';
}

最終實現效果：
