php数组三维转二维

php数组三维转二维

当心，上代码：

// 测试用的数组
$my_array = array (
    '0'=>array(
            '0'=>array('no'=>1212,'ret'=>'09'),
            '1'=>array('no'=>1213,'ret'=>'09'),
            '2'=>array('no'=>1214,'ret'=>'09'),
        ),
    '1'=>array(
            '0'=>array('no'=>1213,'ret'=>'10'),
            '1'=>array('no'=>1214,'ret'=>'10'),
            '2'=>array('no'=>1215,'ret'=>'10'),
        ),

);

$newhello=array();

$k = 0;
foreach ($my_array as $key => $val) {
    foreach ($val as $key2 => $val2) {
        $newhello[$k]['no'] = $val2['no'];
        $newhello[$k]['ret'] = $val2['ret'];
        $k++;
    }
}

echo '
';
print_r($my_array);
print_r($newhello);
exit();
 
  
打印运行结果：
