請教：PHP中，如何擷取提交的二維數組中某幾列索引值不為空白的結果

所提交的結果如下：

Array(    [name] => Array        (            [0] => 地磚            [1] =>             [2] => 空心磚            [3] => 地磚        )    [cunit] => Array        (            [0] => 塊            [1] =>             [2] => 塊            [3] => 塊        )    [unitprice] => Array        (            [0] => 35            [1] =>             [2] => 3.5            [3] => 35        )    [pronum] => Array        (            [0] => 2            [1] =>             [2] => 2            [3] =>         )    [summoney] => Array        (            [0] =>             [1] =>             [2] =>             [3] =>         ))

$data=$_POST['sale'];//print_r($data);foreach ($data as $k1 => $v1) {foreach ($v1 as $k2 => $v2) {$new_data[$k2][$k1] = $v2;$new_data[$k2]['username']='admin';}}

我想得到的最終結果是。name中數值不為空白，且pronum數值不為空白的結果。試了下if( $v2!=' ) 不對。特請教各位。謝謝了

回複討論(解決方案)

$arr=array(    'name' => array        (            0 =>'地磚',            1 =>'',            2 => '空心磚',            3 => '地磚',        ),    'cunit' => array        (            0 => '塊',            1 => '',            2 => '塊',            3 => '塊'        ),     'unitprice' => array        (            0 => 35,            1 => '',            2 => 3.5,            3 => 35        ),   'pronum' => array       (            0 => 2,            1 => '',            2 => 2,            3 =>''        ),   'summoney' => array        (            0 =>'',             1 =>'',             2 =>'',             3 =>''         )    );$new_data=array();foreach($arr as $k=>$v){    if($k=='name' || $k=='pronum'){        foreach($v as $newk=>$newv){            if($newv!=''){                $new_data[$k][]=$newv;            }                    }    }}print_r($new_data);[code=php]Array(    [name] => Array        (            [0] => 地磚            [1] => 空心磚            [2] => 地磚        )    [pronum] => Array        (            [0] => 2            [1] => 2        ))

[/code]

其實處理成這樣才便於後續處理

Array(    [0] => Array        (            [name] => 地磚            [cunit] => 塊            [unitprice] => 35            [pronum] => 2            [summoney] =>         )    [2] => Array        (            [name] => 空心磚            [cunit] => 塊            [unitprice] => 3.5            [pronum] => 2            [summoney] =>         ))

$k = array_keys($data);foreach(call_user_func_array('array_map', array_merge(array(null), $data)) as $i=>$r) {  $r = array_combine($k, $r);  if($r['name'] && $r['pronum']) $res[$i] = $r;}

謝謝xuzuning版主。這樣處理周全點，同時謝謝luo19880415
