Question

我有一个问题：我正在使用MySQL为PHP网站制作多语言系统。这是通过使用会话和cookie来设置变量来完成的，它将告诉mysql_query从数据库中选择哪些数据。我给你一个片段： lang.php：

<?php
ob_start();
session_start();
header('Cache-control: private');

if(isset($_GET['lang'])){
$lang = $_GET['lang'];
$_SESSION['lang'] = $lang;
setcookie("thomasvanvugt_lang", $lang, time() + (3600 * 24 * 30));
} else if(isset($_SESSION['lang'])){
$lang = $_SESSION['lang'];
} else if(isset($_COOKIE['thomasvanvugt_lang'])){
$lang = $_COOKIE['thomasvanvugt_lang'];
} else {
$lang='nl';
}

switch ($lang) {
    case "nl":
    $web_lang="nl";
    break;

    case "en":
    $web_lang="en";
    break;

    case "de":
    $web_lang="de";
    break;

    case "fr":
    $web_lang="fr";
    break;

    default:
    $web_lang="nl";
}
?>

footer.php

<?php
$text_footer = mysql_query("SELECT * FROM text_footer WHERE lang='$web_lang' AND line='copyright'");
while($text_footer_row = mysql_fetch_array($text_footer)){
    $text_footer_copyright = $text_footer_row['text'];
}
$text_footer = mysql_query("SELECT * FROM text_footer WHERE lang='$web_lang' AND line='about'");
while($text_footer_row = mysql_fetch_array($text_footer)){
    $text_footer_about = $text_footer_row['text'];
}
$text_footer = mysql_query("SELECT * FROM text_footer WHERE lang='$web_lang' AND line='adres'");
while($text_footer_row = mysql_fetch_array($text_footer)){
    $text_footer_adres = $text_footer_row['text'];
}
?>

是的，我是荷兰人。所以，如果我是，请不要介意我：有点愚蠢，不擅长英语等。我的问题是，我可以缩短这段代码：

<?php
$text_footer = mysql_query("SELECT * FROM text_footer WHERE lang='$web_lang' AND line='copyright'");
while($text_footer_row = mysql_fetch_array($text_footer)){
    $text_footer_copyright = $text_footer_row['text'];
}
$text_footer = mysql_query("SELECT * FROM text_footer WHERE lang='$web_lang' AND line='about'");
while($text_footer_row = mysql_fetch_array($text_footer)){
    $text_footer_about = $text_footer_row['text'];
}
$text_footer = mysql_query("SELECT * FROM text_footer WHERE lang='$web_lang' AND line='adres'");
while($text_footer_row = mysql_fetch_array($text_footer)){
    $text_footer_adres = $text_footer_row['text'];
}
?>

问候，托马斯。

Answer 1

$query = mysql_query("SELECT * FROM text_footer WHERE lang='$web_lang' AND line IN ('copyright', 'about', 'adres')");
while ($row = mysql_fetch_array($footerTexts)) {
    $line = $row['line'];
    $footerTexts[$line] = $row['text'];
}
echo $footerTexts['copyright'];

Answer 2

$text = mysql_query("SELECT * FROM text_footer WHERE lang='$web_lang' AND line IN  ('copyright' , 'about' , 'adres') ORDER BY line");

while($text_row = mysql_fetch_array($text)){
   switch($text_row['line']){
        case 'copyright' : 
            $text_footer_copyright = $text_row['text'];
            break;
        case 'about' : 
            $text_footer_about = $text_row['text'];
            break;
        case 'adres' :
            $text_footer_adres = $text_row['text'];
            break;
    }
}

写入时间可能更长，但执行速度更快，因为您只执行一次SQL查询。
