多维数组循环获取值

Question

I have an array of multiple arrays all with different levels. What im trying to do is loop though the array by key, and it will go through each level getting the values for those keys. myArray looks something like this

Array ( [0] => 
  Array ( [Date] => 2011-15-22 
          [Color] => blue
          [Status] => Fresh 
        [1] => 
  Array ( [Date] => 1999-08-04 
          [Color] => green
          [Status] => Rotten) )

I have tried

foreach($myArray as $row){
  foreach($row["Date"] as $k){
     echo $k
    } 
 }

I am getting an

Notice: Undefined index: Date 

and

Warning: Invalid argument supplied for foreach() 

Answer 1

Simply with array_walk_recursive function:

$arr = [
    [ 'Date' => '2011-15-22', 'Color' => 'blue', 'Status' => 'Fresh' ],
    [ 'Date' => '1999-08-04', 'Color' => 'green', 'Status' => 'Rotten' ]
];

array_walk_recursive($arr, function($v, $k){
    if ($k == 'Date') echo $v . PHP_EOL;
});

The output:

2011-15-22
1999-08-04
