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();
```
