PHP解析语法错误

Question

我是PHP的新手,我面临语法错误.

码:

<?php

    // configuration
    require("../includes/config.php");

    // if form was submitted
    if ($_SERVER["REQUEST_METHOD"] == "POST")
    {
        if(empty($_POST['username'])) || empty($_POST['password'] || $_POST['password'] != $_POST['confirmation']){
            apologize('You did something wrong!');
        }
    }
    else
    {
        // else render form
        render("register_form.php", ["title" => "Register"]);
    }

?>

错误:

解析错误:语法错误,意外'||' (T_BOOLEAN_OR),在第9行的/home/jharvard/vhosts/localhost/html/register.php中期待')'

我是PHP的新手,这个代码有可能存在多个错误.作为参考,道歉只是简单地呈现一个抱歉消息以及其他输入,而渲染只是一个用模板简化渲染过程的功能.

更改:

if(empty($_POST['username'])) || empty($_POST['password'] || $_POST['password'] != $_POST['confirmation']){

至:

if(empty($_POST['username']) || empty($_POST['password']) || $_POST['password'] != $_POST['confirmation']){
                           ^                            ^
