使用 foreach 循环遍历关联数组的关联数组 [英] Loop through associative array of associative arrays using foreach loop

问题描述

$students = array(
    'rishab' => array(
        'age' =>25 ,
        'marks' =>400,
        'class' =>'MCA'
     ), 
     'kamran' => array(
        'age' =>23 ,
        'marks' =>550,
        'class' =>'MBA'
     ),
     'Sunil'  => array(
         'age' =>23 ,
         'marks' =>550,
         'class' =>'MBA'
     )
); 

如何使用 foreach 循环遍历这个 php 关联数组?

how can i loop through this php associative array using foreach loop??

推荐答案

你可以做一个双 foreach 来循环所有子数组的所有值.

You can make a double foreach to loop all values of all sub arrays.

foreach($students as $key => $value) {
    echo 'Key: '.$key.'<br />';
    foreach($value as $s_key => $s_value) {
        echo 'Sub key: '.$s_key.' => '.$s_value.'<br />';
    }
    echo '<br />';
}

结果:

Key: rishab
Sub key: age => 25
Sub key: marks => 400
Sub key: class => MCA

Key: kamran
Sub key: age => 23
Sub key: marks => 550
Sub key: class => MBA

Key: Sunil
Sub key: age => 23
Sub key: marks => 550
Sub key: class => MBA
