刪除包含從多維數組在PHP

Question

空值有了這種簡單陣列的整個子陣：

array(3) { 
    [0]= 
    array(5) { 
    [0]= 
    string(61) "ramdom test" 
    [1]= 
    string(7) "19" 
    [2]= 
    string(7) "-99" 
    [3]= 
    string(6) "ramdom test" 
    [4]= 
    string(31) "ramdom test" 
    } 
    [1]= 
    array(5) { 
    [0]= 
    string(61) "ramdom test 2" 
    [1]= 
    string(7) "87" 
    [2]= 
    string(7) "-42" 
    [3]= 
    string(6) "NULL" // <--------------------------- THIS HAS A NULL VALUE 
    [4]= 
    string(31) "ramdom test 2" 
    } 
    [2]= 
array(5) { 
    [0]= 
    string(61) "ramdom test 3" 
    [1]= 
    string(7) "54" 
    [2]= 
    string(7) "-67" 
    [3]= 
    string(6) "ramdom test 3" 
    [4]= 
    string(31) "ramdom test 3" 
    } 
} 

我想刪除包含NULL值的整個子陣，在這種情況下，關鍵陣列的[3]有空，所以我想如何刪除整個[1]陣列，以便我可以得到所需的輸出？

array(2) { 
    [0]= 
    array(5) { 
    [0]= 
    string(61) "ramdom test" 
    [1]= 
    string(7) "19" 
    [2]= 
    string(7) "-99" 
    [3]= 
    string(6) "ramdom test" 
    [4]= 
    string(31) "ramdom test" 
    } 
    [1]= 
array(5) { 
    [0]= 
    string(61) "ramdom test 3" 
    [1]= 
    string(7) "54" 
    [2]= 
    string(7) "-67" 
    [3]= 
    string(6) "ramdom test 3" 
    [4]= 
    string(31) "ramdom test 3" 
    } 
} 

我使用：

$myArray = array_map('array_filter', $myArray); 

但這刪除我的只有空項目，而不是整個子陣列。

使用array_filter功能：

$result = array_filter($array, function($v){ 
    return !in_array(null, $v, true); 
}); 

# fix keys 
$result = array_values($result);
