Question

我需要将m.php中的数组传递回index.php并循环打印每一行，但我找不到怎样的方法呢？任何建议将不胜感激。

在代码下面我在m.php中使用return $ rows但是index.php无法获取它..

的index.php

<?php
require 'm.php';

$select_news = new select_news();
$select_news->select_3();
print_r($rows);
foreach ($rows as $row){
?>
<div><?=$row['id']?></div>
...
<?php
}
?>

m.php

class select_news{
    public function select_3(){
        global $db;
        $sth = $db->prepare('SELECT * FROM news ORDER BY id DESC LIMIT 3');
        $sth->execute();
        $rows = $sth->fetchAll();
            return $rows;
    }
}

Answer 1

只需将该函数调用的值赋给变量...

$select_news = new select_news();
$rows = $select_news->select_3();
print_r($rows);
foreach ($rows as $row){
?>
<div><?=$row['id']?></div>
...
<?php
}
?>

要将其转换为数组（如果我正确阅读了问题），您可以将其放在foreach语句的正上方：

$rows = unserialize(serialize(json_decode(json_encode((array) $rows), 1)));

如何从类传递数组
