mysql - php回显问题

Question

$this->get_name = mysqli_fetch_assoc(mysqli_query($this->link,"SELECT complete_name FROM student WHERE email='$this->email'"));

mysqli_query($this->link, $this->drop_query) or die(mysql_error());

echo $this->get_name['complete_name'].  " has been marked as Left!";

当我运行它时，我得到以下信息:

“约翰已被标记为左派!”

但是当我运行的时候

echo ".$this->get_name['complete_name'] has been marked as Left!";

我明白了:

“数组['complete_name'] 已被标记为左!”

他们不应该打印相同的东西吗？

Answer 1

第二种情况PHP:s解析器不知道变量在哪里结束，使用{}将变量封装在字符串中

echo "{$this->get_name['complete_name']} has been marked as Left!";
