ThinkPHP为了节省一些重复的步骤，写了个简单版的生成model的工具，逆向生成model代码，节省时间，专注写业务代码。
ThinkPHP中的命令行也提供了一些生成代码的命令：

make:controller  创建控制器
make:model 创建模型
make:middleware 创建中间件

ThinkPHP也提供了逆向生成model的命令：optimize:autoload，但是提示：Command “optimize:autoload” is not defined.
于是就算了，也不想去研究它。还不如直接写一个。

下面是一个简单的逆向工程工具实现代码：

<?phpnamespace app\controller;use app\BaseController;
use think\Request;
use think\Facade\Db;class GeneratorController extends BaseController
{static $schema = "shushan";public function generator(){//获取表名$tables = Db::query("SELECT TABLE_NAME  as 'name'from information_schema.tables WHERE TABLE_SCHEMA = :dataBase", ["dataBase" => GeneratorController::$schema]);foreach ($tables as $key => $value) {foreach ($value as $item) {//获取字段名称和备注$COLUMNS = Db::query("select COLUMN_NAME,DATA_TYPE,COLUMN_COMMENT from information_schema.COLUMNS where table_name = :itemand table_schema = :dataBase", ["item" => $item, "dataBase" => GeneratorController::$schema]);$file = fopen("tempFile/" . GeneratorController::snakeToCamel($item) . ".php", "w");fwrite($file, "<?php" . PHP_EOL . "namespace app\model;" . PHP_EOL. PHP_EOL . "use think\model;" . PHP_EOL. PHP_EOL . "class " . GeneratorController::snakeToCamel($item) . " extends Model". PHP_EOL . "{" . PHP_EOL);$content = "//设置字段信息" . PHP_EOL ."protected $" . "schema = [" . PHP_EOL;fwrite($file, $content);//写入字段foreach ($COLUMNS as $COLUMN) {$content = "'" . $COLUMN["COLUMN_NAME"] . "'" . "       =>"  ."'" . $COLUMN["DATA_TYPE"] . "'" . "," . "//" . $COLUMN["COLUMN_COMMENT"] . PHP_EOL;fwrite($file, $content);}$content = PHP_EOL . "];";fwrite($file, $content);fwrite($file, PHP_EOL . "}");fclose($file);}}return $this->success();}static function snakeToCamel($str, $capitalized = true){$result = str_replace('_', '', ucwords($str, '_'));if (!$capitalized) {$result = lcfirst($result);}return $result;}
}

生成的效果：
