Hello,
I'm learning PHP from w3schools.com but they didn't explain everything clearly,
see that page,
http://www.w3schools.com/php/php_file_upload.asp

I want to know the meaning of this line , how it is checking the error in uploading ?

if ($_FILES["file"]["error"] > 0)

When you upload the file the php will check the file for errors and limitations. The php has come error codes and string formats to check the file errors.

$_FILES["file"]["error"] is used to check for file uploading errors... so if $_FILES["file"]["error"] is greater than zero then its means that there is an error encountered during upload.
