使用 laravel phpexcel 删除多维数组中的空数组
Remove empty array in multidimensional array using laravel phpexcel
如果元素为空或计数为“0”，我想删除数组。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

如果 array[1] ,array[2].. 为空或计数“0”意味着它应该被删除，或者如果有任何其他解决方案可以避免使用 phpexcel 在 laravel.
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);
