PHP错误-意外的require_once预期功能 [英] Php Error - Unexpected require_once expecting function

问题描述

我目前正在尝试获取medoo框架，以便可以轻松地从MySQL数据库中检索数据...由于某种原因，它不起作用！

I'm currently trying to fetch the medoo framework so that I can begin easily retrieving data from my MySQL database... and for some reason it doesn't work!

这是我的 signin.php 文件的代码

<?php
    function loginUserAccount($loginname, $password){
    // Include Medoo (configured)
    require_once 'medoo.min.php';

    // Initialize
    $database = new medoo();

    $email = $database->get('MM_Users', 'Email', [
        'ID' => 1
    ]);
    return $email;
    }
    ?>

错误:

分析错误:语法错误，意外的'require_once'(T_REQUIRE_ONCE)，/myfiledirectory/example.php 中的期望函数(T_FUNCTION)，位于 4

Parse error: syntax error, unexpected 'require_once' (T_REQUIRE_ONCE), expecting function (T_FUNCTION) in /myfiledirectory/example.php on line 4

任何帮助将不胜感激！我不太确定发生了什么事情.

Any help is greatly appreciated! I'm not quite sure at what's going wrong.

正在运行的php文件是:

The php file that's running is :

<?php
require_once('signin.php');
if(!loginUserAccount('[e-mail]', 'AveryRandomPassword')){

    echo 'error';
} else {
    echo $email;
}
?>

require_once的包装也有所​​不同……这没什么不同吗?如果是这样，更建议在生产环境中使用哪一个?

There's also a difference in the wrapping for require_once... this doesn't make a difference does it? And if so, which one is more advisable to use in a production environment?

推荐答案

没有函数的类中不能包含require_once. 这是主要原因.

You can't have require_once inside a class without a function. That's the main reason.

尝试将require_once放入construct.

确切地说:

class foo 
{
    require_once('bar.php');
}

将引发错误.
