Php Error - Unexpected require_once expecting function

问题

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!

here's the code of my signin.php file

<?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;
    }
    ?>

And the error:

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

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

The php file that's running is :

<?php
require_once('signin.php');
if(!loginUserAccount('bobby@gmail.com', 'AveryRandomPassword')){

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

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?

回答1:

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

Try putting the require_once in the construct.

to be exact :

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

will thro an error.

回答2:

This line:

require_once('signin.php');

is inside a class but outside a method, which is not possible in PHP.

回答3:

I might be wrong, but doesn't require_once 'medoo.min.php'; require parentheses? like so: require_once ('medoo.min.php');
