TP5 提示Namespace declaration statement has to be the very first statement in the script

utf-8 bom头问题 thinkphp 报错 Namespace declaration statement has to be the very first statement in the script

<?phpnamespace app\admin\controller;//命令空间use think\controller;class Entry extends Controller{//首页public function index(){echo 'Hello,ThinkPHP!';}}

在访问上面的代码页面里，出现了

Namespace declaration statement has to be the very first statement in the script

这样的错误，我搜索了网上，很幸运的到了答案，原来是在保存文件的过程格式应该选择utf-8无BOM型。
