Php 语法错误，意外的“public”（T_public）

我得到一个错误，这是对我大喊大叫，似乎是一个语法错误？ 我真的不知道我哪里出错了？

public function upload() {
  // getting all of the post data
  $file = array('image' => Input::file('image'));
  // setting up rules
  $rules = array('image' => 'required',); //mimes:jpeg,bmp,png and for max size max:10000
  // doing the validation, passing post data, rules and the messages
  $validator = Validator::make($file, $rules);
  if ($validator->fails()) {
    // send back to the page with the input data and errors
    return Redirect::to('upload')->withInput()->withErrors($validator);
  }
  else {
    // checking file is valid.
    if (Input::file('image')->isValid()) {
      $destinationPath = 'uploads'; // upload path
      $extension = Input::file('image')->getClientOriginalExtension(); // getting image extension
      $fileName = rand(11111,99999).'.'.$extension; // renameing image
      Input::file('image')->move($destinationPath, $fileName); // uploading file to given path
      // sending back with message
      Session::flash('success', 'Upload successfully'); 
      return Redirect::to('upload');
    }
    else {
      // sending back with error message.
      Session::flash('error', 'uploaded file is not valid');
      return Redirect::to('upload');
    }
  }
}

如果您不在类中，请使用函数上载，而不是公共函数上载

如果您在类中，则错误位于您提供的代码之前。

您需要一个类上下文来使用访问标识符

您的代码应该是：

class MyClass {
    public function upload() {
      // getting all of the post data
      $file = array('image' => Input::file('image'));
      // setting up rules
      $rules = array('image' => 'required',); //mimes:jpeg,bmp,png and for max size max:10000
      // doing the validation, passing post data, rules and the messages
      $validator = Validator::make($file, $rules);
      if ($validator->fails()) {
        // send back to the page with the input data and errors
        return Redirect::to('upload')->withInput()->withErrors($validator);
      }
      else {
        // checking file is valid.
        if (Input::file('image')->isValid()) {
          $destinationPath = 'uploads'; // upload path
          $extension = Input::file('image')->getClientOriginalExtension(); // getting image extension
          $fileName = rand(11111,99999).'.'.$extension; // renameing image
          Input::file('image')->move($destinationPath, $fileName); // uploading file to given path

          return Redirect::to('upload');
        }
        else {
          // sending back with error message.
          Session::flash('error', 'uploaded file is not valid');
