Why this php example used basename function?

[Uday4all]

Source page: http://www.w3schools.com/php/php_file_upload.asp

In the file upload script,the example contains the following line of code

$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);

 

 

but why it should not be like?

$target_file = $target_dir . $_FILES["fileToUpload"]["name"];

 

i mean without using basename function

Because good ol IE screwed it up, as usual, and for security reasons http://stackoverflow.com/questions/2347056/isnt-using-the-basename-function-with-filesuserfilename-redundant
