创建一个用于动态翻译内容的 php 文件答案

【问题标题】：Creating a php file for translating the content dynamically创建一个用于动态翻译内容的 php 文件

【问题描述】：

我有一个包含大约 700 个术语的数据库。我只想编写一个名为 internationalize 的单个 php 文件，该文件将检查 mysql 数据库并返回正确的翻译。所有 PHP 变量都已设置，并且有一个包含所有语言翻译的视图。大约有 11 种语言。我看了很多地方，但没有一个适合我的情况。任何建议将不胜感激。

if (!isset($_SESSION))
{
    session_start();
}

if (isset($setup))
{
    $lang=$_SESSION['setupLang'];
}
elseif (isset($_SESSION['lang']))
{
    $lang=$_SESSION['lang'];
}
else
{
require("fetchMainConfig.php");
}

$lang_code = $lang; 
//file_dir contains the language codes for example: il,fr,pt,ge and so on
$sql = "SELECT file_dir FROM `hydroserver_translation`.`language_file_dir`";
if($lang_code = $sql){
    // What should go in here??? What is the best way to
    // dynamically translate the database?
}

我还附上了数据库视图的副本。我打算这样写代码，如果没有语言翻译，默认翻译是英文。

【问题讨论】：

有什么理由不使用 gettext 和 POT 文件？
您要翻译什么文字？我不明白输入是什么。
看起来脚本根据所选择的语言为 php 变量赋值。该脚本似乎生成了几个变量，这些变量从数据库中获取其值并用于脚本的其余部分。
我们希望在翻译时为用户提供更大的灵活性。由于数据库和网站包含多个科学变量，最好让用户输入翻译数据。 @A.L 这些是我们用来在网站上显示信息的所有 php 变量。所以我们基本上是在翻译整个网页的内容。
我认为如果你有值和翻译，你想创建一个变量，$value 可以为每个值访问。你可以写$$database_result["value"] = translation。这个链接解释了它是如何工作的：php.net/manual/en/language.variables.variable.php 但这也可能会覆盖 php 中的重要变量或函数，所以我不推荐这种方法。为此最好使用数组，因为从数组中存储和检索数据更容易。

这就是我所做的并且有效。感谢您的帮助！

<?php
