Rgd：获取数组密钥PHP

Question

我有这个饭_input_array

   [Chicken Breast] => 11
    [Marinated Dory] => 1
    [Beef] => 3

foreach($meal_input_array as $meal_input_key => $meal_input_quantity)
{

$meal_data = $mean_input_key . "**" . $meal_input_quantity;
echo $meal_data;
}

当我回显结果时，我无法获得密钥，

**11**1**3**0

数组键名未分配给$ meal_data，我可以查看我的代码是否有错误。

谢谢！

它有效

<?php
$meal_input_array=array('Chicken Breast' => 11, 'Marinated Dory' => 1,'Beef' => 3);
//print_r($meal_input_array);
 foreach($meal_input_array as $meal_input_key => $meal_input_quantity)
 {
 //echo $meal_input_key;
 $meal_data = $meal_input_key. "  **  " .$meal_input_quantity;
 echo $meal_data;
}
