Php Can'；t从CodeIgniter下的foreach循环检索值

我无法在CodeIgniter视图中从$info（如下所述）检索值

以下是场景： 我解释了代码中的所有内容

function info() {
{...} //I retrieve results from database after sending $uid to model.
    $dbresults = $this->my_model->get_info($uid); //Assume that this model returns some value.


    foreach($dbresults as $row) {
        $info = $row->address; //This is what I need to produce the results
        $results = $this->my_model->show_info($info);

    return $results; //This is my final result which can't be achieved without using $row->address. so first I have to call this in my controller.

    }

    // Now I want to pass it to a view

    $data['info'] = $results;
    $this->load->view('my_view', $data);

    //In my_view, $info contains many values inherited from $results which I need to call one by one by using foreach. But I can't use $info with foreach because it is an Invalid Parameter as it says in an error.

---

请从中删除返回语句

foreach($dbresults as $row) {
    $info = $row->address; //This is what I need to produce the results
    $results[] = $this->my_model->show_info($info);
    //  return $results; remove this line from here;
}

$data['info'] = $results; // now in view access by $info in foreach
$this->load->view('my_view', $data);

现在$info可以在视图中访问

希望这对你有帮助

在

foreach

内部使用

$result

是不合理的。因为在每个循环中，$result将接受一个新值。因此，最好将其用作

数组

，然后将其传递给视图。此外，您不应该在

foreach

中使用

return

function info() {
{...} //I retrieve results from database after sending $uid to model.
    $dbresults = $this->my_model->get_info($uid); //Assume that this model returns some value

$result = array();
    foreach($dbresults as $row) {
        $info = $row->address; //This is what I need to produce the results
        $result[] = $this->my_model->show_info($info);

    }

    // Now I want to pass it to a view

    $data['info'] = $result;
    $this->load->view('my_view', $data);
}

要检查$result数组执行的操作，请执行

var\u导出（$result）或
变量转储（$result）在
foreach
结束后。并确保这是您要发送到视图的内容

现在，在您看来，您可以执行以下操作：

<?php foreach ($info as $something):?>

//process

<?php endforeach;?>
