Question

所以我想从文件$username访问变量（quickprotect.login.php）并将其打印在文件index.php中。文件login.ini.php包含用户名配置，quickprotect.login.php包含：

<?php
$root = dirname(__FILE__);

class quickprotect {
    private $ini_file_location = "login.ini.php";
    private static $tries;
    public static $errormsg;

    public $settings;

    public function __construct() {
        session_start();
        $this->ini_file_location = $GLOBALS[root] . "/" . $this->ini_file_location;
        $this->settings = @parse_ini_file($this->ini_file_location);
        if (!$this->settings) {
            die("Failed to load the INI file located at: $this->ini_file_location.");
        }
    }

    public function login($username, $password) {

        // Performs login by initializing $_SESSION vars
        // Returns true or false, plus $_SESSION message on success/failiure
        // Contains brute force protection

        if (!isset($_SESSION['tries'])) $_SESSION['tries'] = 1;
        if ($_SESSION['tries'] <= intval($this->settings[MAX_TRIES]) || $this->settings[ALLOW_UNLIMITED_TRIES] == true) {
            //Try to prevent brute forcing
            if (sha1(trim($password)) == trim($this->settings[ADMIN_PW]) && $username === $this->settings[USERNAME]) {
                // other codes
            }
        }
    }
}

当我使用时：

include 'quickprotect.login.php';
echo "User: $username";

它给出了：

User:

任何人都可以提供建议吗？ Thx提前:)）

更新：通过以下方式解决：

include '../quickprotect.class.php'
$qp = new quickprotect();
$un=   $qp->settings['USERNAME']; 
mail("mail@domain.com","Report","=== Username: $un");

Answer 1

如果您在其他页面上使用表单，则可以使用php $ _POST

Answer 2

你确定你写过这个吗？

echo "User: $username";

因为它应该是

echo "User: ".$username;

获取变量的实际值。

如何从其他文件访问PHP变量？
