@ is the error supression operator in php, you won't see any error if the file is not found in that statement.

@ is the shut-up operator. If something goes wrong, no error message will be shown. It's usually a bad practice to use it; first because error messages happen for a good reason, and second because it's ridiculously slow for what it does.

It's roughly equivalent to wrapping the statement in:

$oldErrorLevel = error_reporting(0);
// the statement
error_reporting($oldErrorLevel);

Here's the link to the PHP manual page documenting it.

@ before a function call suppresses any errors that function would normally output.

In the case of include, the person doing that wants the script to keep going if block.php isn't present. A better way of doing this is usually to do something like this instead:

if(is_readable('block.php')) {
  include('block.php');
}
