使用laravel phpexcel删除多维数组中的空数组

Question

我想删除数组，如果元素为空或计数＆＃39; 0＆＃39;。我在laravel中使用了PHPEXCEL。

我的代码：

$results=Excel::load('assets/uploads/studentdata/file.xlsx', function($reader) {

})->get()->toArray();

我得到的输出如下，

Array ( [0] => Array ( [grade] => 12 [schoolentrancedate] => Carbon\Carbon Object ( [date] => 2014-09-02 00:00:00 

[timezone_type] => 3 [timezone] => UTC ) [schoolexitdate] => Carbon\Carbon Object ( [date] => 2015-06-25 00:00:00 

[timezone_type] => 3 [timezone] => UTC ) [studentfirstname] => Gutierrez [studentmiddlename] => [studentlastname] => Larry 

[age] => [gender] => M [dateofbirth] => Carbon\Carbon Object ( [date] => 1997-06-16 00:00:00 [timezone_type] => 3 [timezone] 

=> UTC ) [language] => [parentfullname] => Irma Perlera [phone] => 617-778-3913 [mobile] => 617-778-3913 [parentemail] =>

[fridayintime] => Carbon\Carbon Object ( [date] => 2015-03-16 08:10:00 [timezone_type] => 3 [timezone] => UTC ) 

[fridayouttime] => Carbon\Carbon Object ( [date] => 2015-03-16 14:30:00 [timezone_type] => 3 [timezone] => UTC ) [note] => 

[oneway] => [fromhome] => [fromschool] => [twoway] => [43] => ) 


[1] => Array ( [grade] => [schoolentrancedate] => [schoolexitdate] => [studentfirstname] => [studentmiddlename] => 

[studentlastname] => [age] => [gender] => [dateofbirth] => [language] => [parentfullname] => [phone] => [mobile] => 

[parentemail] => [emergencypersonfullname] => [emergencypersonphone] => [emergencypersonmobile] => [house] => [apartment] => 

[street] => [city] => [state] => [zipcode] => [weekdayfrom] => [weekdayto] => [intime] => [outtime] => [mondayintime] => 

[mondayouttime] => [tuesdayintime] => [tuesdayouttime] => [wednesdayintime] => [wednesdayouttime] => [thursdayintime] => 

[thursdayouttime] => [fridayintime] => [fridayouttime] => [note] => [oneway] => [fromhome] => [fromschool] => [twoway] => [43] 

=> ) 

[2] => Array ( [grade] => [schoolentrancedate] => [schoolexitdate] => [studentfirstname] => [studentmiddlename] => 

[studentlastname] => [age] => [gender] => [dateofbirth] => [language] => [parentfullname] => [phone] => [mobile] => 

[parentemail] => [emergencypersonfullname] => [emergencypersonphone] => [emergencypersonmobile] => [house] => [apartment] => 

[street] => [city] => [state] => [zipcode] => [weekdayfrom] => [weekdayto] => [intime] => [outtime] => [mondayintime] => 

[mondayouttime] => [tuesdayintime] => [tuesdayouttime] => [wednesdayintime] => [wednesdayouttime] => [thursdayintime] => 

[thursdayouttime] => [fridayintime] => [fridayouttime] => [note] => [oneway] => [fromhome] => [fromschool] => [twoway] => [43] 

=> )  )

如果array [1]，array [2] ..为空或计数＆＃39; 0＆＃39;我需要删除上面的数组意味着它应该被移除或者如果有任何其他解决方案以避免在laravel中使用phpexcel读取空行。

试试这个..

  $data="your array";

    for($i=0;$i<count($data);$i++)
    {
    $countstring=count(array_filter($data[$i]));
    if($countstring==0)
    {
    unset($data[$i]);  // remove empty array
    } else {
    $finaldata[] =$data[$i];  //get non empty array
    }
    }
    print_r($finaldata);
