Question

我在包含文件中访问数组时遇到问题。代码仅在我直接包含en.php时才有效。 Mayby我无法访问数组单词，因为en.php是＆＃34; sub-included＆＃34;？

的index.php

<?php
include 'localization/langSwitcher.php';
echo $words['title'];

langSwitcher.php

<?php

function SetLanguage()
{
    if(isset($_COOKIE['lang']))
    {
        switch ($_COOKIE['lang']) {
            case 'en':
                include 'localization/en.php';
                break;

            default:
                include 'localization/en.php';
                setcookie('lang', 'en', time() + 365 * 24 * 3600, '/');
                break;
        }
    }
    else
        setcookie('lang', 'en', time() + 365 * 24 * 3600, '/');
}

SetLanguage();

en.php

<?php
$words = array(
    'title' => 'Welcome on Trex where you can buy or sell via Internet!', 
    '' => ''
);

作为函数中包含的文件 - 此函数中的所有变量在函数外部都不可用。

因此，您应该使用global关键字，例如：

$words = array();
function SetLanguage()
{
    global $words;   // here

    if(isset($_COOKIE['lang']))
    {
        switch ($_COOKIE['lang']) {
            case 'en':
                include 'localization/en.php';
                break;

            default:
                include 'localization/en.php';
                setcookie('lang', 'en', time() + 365 * 24 * 3600, '/');
                break;
        }
    }
    else
        setcookie('lang', 'en', time() + 365 * 24 * 3600, '/');
}

SetLanguage();

或者你的函数可以返回$words执行结果。
