数组到字符串(php)

Question

请帮我转换数组到字符串.

数组看起来像这样:

Array
(
    [0] => Array
        (
            [0] => Array
                (
                    [red] => 255
                    [green] => 255
                    [blue] => 255
                    [alpha] => 127
                )

            [1] => Array
                (
                    [red] => 255
                    [green] => 255
                    [blue] => 255
                    [alpha] => 127
                )
             ...

        )

)

我试图使用implode函数,但没有结果......

$string = implode(", ", $pxlCorArr);

PS:对不起我来自乌克兰的英语.

阵:

$pxlCorArr = 
  array(
      array (
           array('red' => 255, 
                 'green' => 255,
                 'blue' => 255,
                 'alpha' => 127
           ),

           array('red' => 255,
                 'green' => 255,
                 'blue' => 255,
                 'alpha' => 127
           )
      )
  );

码:

$output = '';
foreach ($pxlCorArr as $subArray) {
    if(is_array($subArray)) {
        foreach ($subArray as $subArray2) {
            if(is_array($subArray2)) {
                $output .= implode ('.', $subArray);
                $output .= ',';
            }
        }
    }
}
$output = rtrim($output, ',');

输出:

255.255.255.127,255.255.255.127
