Yii2 using Phpexcel to export form times wrong

is to use composer installation finished phpexcel, report such a mistake is how to return

Add:
1. The code package is installed through composer, Yii2 requires a namespace, Phpexcel is not with a namespace,
2. The test file quoted phpexcel.php file when the error, reported "Namespace missing?",
3. I added the namespace, and this time I reported another mistake, "Class ' commonextensionsphpexcel_calculation ' not Found",
4. I went to find this class, find him in the calculation.php file, and then I put the calculation.php file to add a namespace introduced, but still report this fault, how broken how broken,
5. I changed the calculation.php file name to phpexcel_calculation.php, and then I got the error in the picture.

Hint written by xxx func not found

' You this error is not found relative to the class dependent class for find '.

First confirm whether the installation is successful and see if the code package is downloaded.
Then according to YII2 to introduce the package in the class mechanism {take an example laravel composer download good after you need to configure cofing/app.php file}
And then test it if it doesn't work.

Write a test directly for the PHP file test is useful

1. Go inside to see if this class is not in, if you require introduce phpexcel before calling the portal file

This does not seem to be installed with composer, if it is directly available. You check to see if this is composer installed.
