Hello people,

I was wondering if it is possible to check the uploaded excel file for its correctness.
If i rename for example photo.jpg file into fakeexcel.xls, upload it to my php page, i get an error Fatal error: Uncaught exception 'Exception' with message '
This is pretty logically, but is there a way to check the file first and give a decent error message?

Many thanks in advance,

A try-catch block might suffice for catching exceptions. This is like branching. Example:

try {
    $excel = $reader->load('example.xls');

} catch (Exception $e) {
    echo $e->getMessage();

At least the case you are describing will usually be caught, but it is not bulletproof.
