解析错误：语法错误，意外的'$ password'（T_VARIABLE）

Question

我检查了一切。它仍然没有工作，当我把分号（;）在第6行它说

Parse error: syntax error, unexpected ';' in line 6 

我该怎么办？这里是我的代码：

<?php 

if(isset($_POST['logintoadminpanel'])) 
( 

    include_once 'connection.php'; 

    $username = $_POST['username']; 
    $password = $_POST['password']; 


    if(empty($username) || empty($password)) 
    (
     echo "Please fill the required fields"; 
    ) 
) 
?> 

Answer 1

您正在使用parens块。你需要使用大括号。

if (...) 
{ 
    ... 
} 

Answer 2

使用{}代替（）for if条件。

<?php 

if(isset($_POST['logintoadminpanel'])) 
{ 

    include_once 'connection.php'; 

    $username = $_POST['username']; 
    $password = $_POST['password']; 


    if(empty($username) || empty($password)) 
    { 
     echo "Please fill the required fields"; 
    } 
} 
?>
