thinkphp如何轻松实现pdf的导出（利用tcpdf插件）

代码编写前先引入tcpdf整个文件夹到项目目录的ThinkPHP文件夹下 如：/ThinkPHP/Library/Vendor/tcpdf

其他的不多说直接上代码

导出考试结果明细

    public function export()
    {
　　　　//  导出考试结果明细(PDF)
        $id = I(&＃39;id&＃39;);
        $detailed = D(&＃39;member_test_result&＃39;);
        $parameter = $detailed->detailedResults($id);
        $name = $parameter[&＃39;member_name&＃39;];
        $result = json_decode($parameter[&＃39;test_result_str&＃39;]);
        foreach ($result as $k => $v) {
            $test = M(&＃39;test_cont&＃39;);
            $array[&＃39;question_title&＃39;] = $test->where(&＃39;id=&＃39; . $k)->getField(&＃39;qustion_title&＃39;);
