An array algorithm problem, three-dimensional array, how to exclude the first layer of each array inside the sub-array inside each element of the sk_id continuous 8 empty array removed?

If the subarray inside a large array has 8 consecutive sk_id of sub-elements inside each element, the sub-array is removed. The data is printed as follows:

Array (+) {[0] =array (+) {[0] = = Array (8) {["Email"] + string (+) "13537951319@163.com" ["sno"] = = string (106725097310815) "[" class_id "] + string (3)" 559 "[" user_id " ] = = string (4) "6648" ["date_time"] + string (Ten) "1473159600" ["ClassName"] + string (15)            "Oh hehe" ["sk_id"] = NULL ["num"] = + int (0)} [1] = = Array (8) { ["Email"] = + string (+) "13537951319@163.com" ["Sno"] + string ("106725097310815" ["Clas s_id "] + string (3)" 559 "[" user_id "] = + string (4)" 6648 "[" date_time "] = + string (10)" 1473          150900 "[" ClassName "] + string (15)" Oh hehe "[" sk_id "] = NULL [" num "] + int (1) } [2] = = Array (8) {["email"] + = string "13537951319@163.com" ["Sno"] =& Gt String (15) "106725097310815 "[" class_id "] + = string (3)" 559 "[" user_id "] + string (4)" 6648 "[" Date_tim            E "] = string (Ten)" 1473147900 "[" ClassName "] + string (15)" Oh hehe "[" sk_id "] = NULL ["num"] = + int (2)} [3] = = Array (8) {["email"] + = string (19) "13537951319@163. com "[" sno "] + = string (106725097310815)" ["class_id"] + string (3) "559" ["User _id "] + string (4)" 6648 "[" date_time "] + string (Ten)" 1473144600 "[" classname "] = = String (          15) "Oh hehe" ["sk_id"] + = NULL ["num"] + int (3)} .....}, [1] =array (+) {[0] = = Array (8) {["E-mail"] = + string (+) "13537951319@163.com" ["s No "] = string (3)" 106725097310815 "[" class_id "] and" 559 "[" user_id "] + string ( 4) "6648" ["DAte_time "] = string (Ten)" 1473159600 "[" ClassName "] and [] + string (15)" Oh hehe "[" sk_id "] = NULL ["num"] + int (0)} [1] = = Array (8) {["email"] + = string (19) "135379513            19@163.com "[" Sno "] and" 106725097310815 "[" class_id "] + string (3)" 559 " ["user_id"] = + string (4) "6648" ["date_time"] = = string (Ten) "1473150900" ["classname"] + = String (15) "Oh hehe" ["sk_id"] = NULL ["num"] = + int (1)} [2] = = Array (8)            {["email] + = string (+)" 13537951319@163.com "[" sno "] + + string (15)" 106725097310815 " ["class_id"] = + string (3) "559" ["user_id"] = + string (4) "6648" ["date_time"] = Strin G (Ten) "1473147900" ["ClassName"] and string (15) "Oh hehe" ["sk_id"] = NULL ["num"] =& Gt   Int (2)}       [3] = = Array (8) {["email"] + = string (+) "13537951319@163.com" ["sno"] + = string (15            ) "106725097310815" ["class_id"] + string (3) "559" ["user_id"] + string (4) "6648" ["Date_time"] + string (Ten) "1473144600" ["ClassName"] and "["] + string (15) "Oh hehe" ["sk_id"] =            NULL ["num"] = + int (3)} ....} ....}

   foreach($arr as $k1 =>$v1){          $z=0;       foreach($v1 as $k2 =>$v2){            if(empty($v2['sk_id'])){                $z=$z+1;            }else{                $z=0;            }            if($z==8){                unset($arr[$k1]);                break;            }       }          }print_r($arr);

Can you look at that?

Write a simple small example, repeat three consecutive, remove the sub-array.

Array:

array(2) {  [0]=>  array(3) {    [0]=>    array(2) {      ["key"]=>      int(0)      ["sk_id"]=>      NULL    }    [1]=>    array(2) {      ["key"]=>      int(1)      ["sk_id"]=>      NULL    }    [2]=>    array(2) {      ["key"]=>      int(2)      ["sk_id"]=>      NULL    }  }  [1]=>  array(3) {    [0]=>    array(2) {      ["key"]=>      int(0)      ["sk_id"]=>      NULL    }    [1]=>    array(2) {      ["key"]=>      int(1)      ["sk_id"]=>      NULL    }    [2]=>    array(2) {      ["key"]=>      int(2)      ["sk_id"]=>      int(1)    }  }}

Code:

$three = array( array( array( 'key' => 0, 'sk_id' => null ), array( 'key' => 1, 'sk_id' => null ), array( 'key' => 2, 'sk_id' => null ), ), array( array( 'key' => 0, 'sk_id' => null ), array( 'key' => 1, 'sk_id' => null ), array( 'key' => 2, 'sk_id' => 1 ), ), ); $result = array(); foreach($three as $key=>$value) { $flag = 0; foreach($value as $k => $v) { if($v['sk_id'] == null) { $flag += 1; } } if($flag < 3) { array_push($result,$value); } } var_dump($result);}

Output:

array(1) {  [0]=>  array(3) {    [0]=>    array(2) {      ["key"]=>      int(0)      ["sk_id"]=>      NULL    }    [1]=>    array(2) {      ["key"]=>      int(1)      ["sk_id"]=>      NULL    }    [2]=>    array(2) {      ["key"]=>      int(2)      ["sk_id"]=>      int(1)    }  }}

You look at this idea, I didn't do the test.

function test($array)    {        $result = array();        foreach ($array as $key => $val) {            $flag = false;            foreach ($val as $k => $v) {                if ($v['sk_id'] != null) {                    $flag = true;                }            }            if ($flag) {                $result[] = $val;            }        }        return $result;    }

foreach ($data $key=>$row){    $i=1;    foreach ($row as $k=>$r){         if (empty($r['sk_id'])){                   $i++;         }            if (!empty($r['sk_id']) && $i<8){            $i=1;         }               if ($i>8){             unset($data[$key]);             break;         }           }}
