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‘];
$k++;
echo ‘<pre />‘;
print_r($my_array);
print_r($newhello);
exit();打印运行结果：
