[LUG] Google escape character- What does @ do in PHP?

[Simon Williams <simon@xxxxxxxxxxxxxxxxxxx>]

This is mad!
I cannot for the life of me find out what google uses as an escape 
character. I'm trying to put an "@" in the search, but google just 
ignores it.

The reason is that I have a line which looks like this:

@mysql_select_db($dbname) or die( "Error: Unable to select database");

It works, but I want to know what the @ does and why it is there.

Thanks
Simon
