$stmt = $conn->query("SELECT DISTINCT(title) as title FROM table WHERE title IS NOT NULL")->fetchAll();
foreach ($stmt as $tag) {
if ($tag['title'] == 'home'){
print_r($tag);
echo 'tag home';
} elseif ($tag['title'] == 'contact'){
print_r($tag);
echo 'tag contact';
}
}
所有页面上的结果都相同:
Array ( [title] => home [0] => home )
tag home
Array ( [title] => contact [0] => contact )
tag contact
所需结果:
home
页上:tag home
contact
页上:tag contact

看起来返回的$ stmt结果包含“ home”和“ contact”标题。
尝试一下:
$stmt = $conn->query("SELECT DISTINCT(title) as title FROM table WHERE title IS NOT NULL")->fetchAll();
foreach ($stmt as $tag) {
var_dump($tag['title']);
}
您将对返回的数据有更好的了解。

在页面上放置一个变量,以指示它是哪个页面。在主页上执行:
$current_page = "home";
并在联系页面上执行:
$current_page = "contact";
然后,您可以仅选择当前所在页面的信息:
$stmt = $conn->query("SELECT * FROM table WHERE title = '$current_page'")->fetchAll(PDO::FETCH_ASSOC);
