Php 分析错误：语法错误，意外'&燃气轮机'；，期望函数（T_函数）或常数（T_常数）

我一直在犯错误

分析错误：语法错误，意外“？>”，应为函数 （T_函数）或常数（T_常数）

从我读到的内容来看，这通常指向一个缺失的“}”，但无论我读了多少遍，所有内容似乎都是匹配的。我还尝试删除其中一个“}”，以防有太多的“}”，但它返回了错误`

分析错误：语法错误，意外的文件结尾

`

这是我的密码：

<?php
class Post{ 
     private $user_obj;
     private $con;

     public function __construct($con, $user){
            $this->con = $con;
            $this->user_obj = new User($con, $user);
     }


     public function submitPost($body, $user_to) {
         $body = strip_tags($body); //removes any HTML tags             
         $body = mysqli_real_escape_string($this->con, $body); //Allows the use of " ' " so it doesn't think it's a new string. 
         $check_empty = preg_replace('/\s+/', '', $body); //Deletes all spaces

注意：首先，您需要改变编码样式和编码模式。

您的注释是否在代码中也被弄乱了，还是因为代码块？在我的例子中，是php版本问题。我从php7.3切换到了7.4，它成功了。希望这句话能对别人有所帮助。
