php - 无法从数组中获取正确的值

Question

我想从下面的数组中获取值

echo "<pre>";
print_r($attachments); 
echo "</pre>";


    Array
    (
        [0] => Array
            (
                [is_attachment] => 
                [filename] =>  Desert.jpg
                [name] =>  Desert.jpg
                [attachment] => 
            )

        [1] => Array
            (
                [is_attachment] => 1
                [filename] => Hydrangeas.jpg
                [name] =>  Hydrangeas.jpg
                [attachment] => 
            )
    )

我使用这段代码来获取值

foreach($attachments as $value)
    { 
        foreach($value as $values)
            { 
                echo $values[filename];
                echo "<br>";
            } 
    }

我得到的O/P是

D
D
H
H

期望的 o/p 应该是

 Desert.jpg
 Hydrangeas.jpg

谁能告诉我哪里错了

不需要两个循环，你可以从单个循环中获取值，因为它是 [0]、[1] 等的外循环。

foreach($attachments as $value)
    { 
        echo $value['filename'];
                echo "<br>"; 
    }
