如何只获取数据库中的值？

Question

当我打印时，我得到的结果如下Array ( [0] => Array ( [subscription_email] => [e-mail] ) [1] => Array ( [subscription_email] => [e-mail] ) )但我想得到它[e-mail], [e-mail]这是我的结果代码$data['subscribers'] = $this->Admin_model->getSubscribers(); $to_email = $data['subscribers'];

Answer 1

您可以简单地循环遍历数组并将每个值添加到变量中。数组或字符串：

<?php

    $dataset = $this->Admin_model->getSubscribers();

    $outputArray = [];

    foreach($dataset as $row) {

       $outputArray[] = $row['subscription_email'];

    }

    // in case you wish for an array

    $to_email = $outputArray;

    // in case you need a comma separated string:

    $to_email = implode(',', $outputArray); 

?>
