多维数组仅返回第一个索引

Question

我知道很多帖子都有相同的标题，不过，我的问题已经部分修复了。

打印阵列：

 $data['posts'] = $this->model_mutamba->getPosts($email);
 print_r('<pre>');
 print_r( $data['posts']);
 print_r('<pre>');

数组：

 Array
(
[0] => Array
    (
        [0] => stdClass Object
            (
                [post_id] => 5
                [aluno_id] => 3
                [post_text] => Hello my name is Joana!
                [post_image] => 
                [post_video] => 
                [post_comments] => 
                [post_likes] => 0
                [post_flags] => 0
                [post_date] => 2014-12-11 03:03:33
            )

    )

[1] => Array
    (
        [0] => stdClass Object
            (
                [post_id] => 3
                [aluno_id] => 1
                [post_text] => Mestre zeca na area!
                [post_image] => 
                [post_video] => 
                [post_comments] => 0
                [post_likes] => 0
                [post_flags] => 0
                [post_date] => 2014-12-10 19:37:16
            )

        [1] => stdClass Object
            (
                [post_id] => 4
                [aluno_id] => 1
                [post_text] => ulalalala
                [post_image] => 
                [post_video] => 
                [post_comments] => 0
                [post_likes] => 0
                [post_flags] => 0
                [post_date] => 2014-12-10 21:00:29
            )

    )

[2] => Array
    (
        [0] => stdClass Object
            (
                [post_id] => 1
                [aluno_id] => 10
                [post_text] => olaaa a todossss
                [post_image] => 
                [post_video] => 
                [post_comments] => 0
                [post_likes] => 0
                [post_flags] => 0
                [post_date] => 2014-12-10 05:18:11
            )

        [1] => stdClass Object
            (
                [post_id] => 2
                [aluno_id] => 10
                [post_text] => mais umas vez estamos aqui e brindar.
                [post_image] => 
                [post_video] => 
                [post_comments] => 0
                [post_likes] => 0
                [post_flags] => 0
                [post_date] => 2014-12-10 15:17:26
            )

    )

)

我在CodeIgniter中的项目，我试图将其循环：

if ("" != $posts) {
    foreach ($posts as $object) { 
        $p = $object[0];
        echo "<br>" . $p->post_text;
    }
}       

它显示帖子中的文字，但不是全部。它仅显示[0]索引中的项目。我也尝试过这样的事情：

$i = -1;
foreach ($posts as $object) { 
    $i++;                             
    $p = $object[$i];
    echo "<br>" . $p->post_text;
}

但是得到＆＃34; Undefined offset 2＆＃34;。

我知道这一定是我想念的简单事。 任何帮助将不胜感激。

Answer 1

你有一个数组，其中每个元素都包含一个对象数组。

$data['posts'] = $this->model_mutamba->getPosts($email);
// just being really explicit to make sure $data['posts'] is a non empty array
if (is_array($data['posts']) && count($data['posts']) > 0) {
    foreach ($data['posts'] as $array_of_objects) { 
        foreach ($array_of_objects as $object) {
            echo "<br>" . $object->post_text;
        }      
    }
}

Answer 2

我使用了@scrowler建议的另一个循环。

$i= 0;
foreach($posts as $object){ 
    $i++; 
    foreach($object as $i=>$p ){
        echo "<br>". $p->post_text;
    }

}

像魅力一样工作。感谢大家的敬意;）
