6年前关闭。

请帮我解决这个错误。 请查看我的代码。

错误是：

"Parse error: syntax error, unexpected '='  in\\...delete_user.php on line 21"

第21行的内容如下：

if ($_SERVER['REQUEST_METHOD'] = = 'POST') {

请帮助。 我不知道如何检查语法，因为我是PHP代码的新手。

谢谢，简

Answer 1

我认为您可能在这里仅剩一些空间：

if ($_SERVER['REQUEST_METHOD'] = = 'POST') { 

试试看（将“ = =“更改为“ = =”）：

if ($_SERVER['REQUEST_METHOD'] == 'POST') { 

Answer 2

尝试删除您的= =之间的空间，使其成为==
