I'm not sure what you are expecting to happen here?

Please refer to the collections documentation https://docs.laravel-excel.com/3.1/imports/collection.html which works the same as ToArray.

If you expect the package to do the DB inserting, use https://docs.laravel-excel.com/3.1/imports/model.html

Maatwebsite\Excel\Concerns\ToArray.For this import concern,can you give me some examples?I read the document imports/concerns,but there just a interface ToArray,and just a neccessary function array,but how to use it it is very ambiguous.Even though i remove this inferface,nothing change for the result.

I just want read file and convert to array.And I want filter the result in array func for implete the ToArray interface.

I don't understand what kind of example you need? The array() method receives an array of rows, you can handle it in the array() method in any way you want.

when i use the ToArray interface,the array function nothing effec in it,look like program not run enter it

Try putting dd($row) in there. We've multiple unit tests backing up this feature.
