Determining if a file exists

I need to execute an IF statement based on whether or not a file exists in
a given folder. If the file is in the folder, do A, if it's not, do B. Is
there a PHP statement that will determine if the file exists?

Any help will be greatly appreciated.

Thanks anyway, but I found it.

if (file_exists($filename))

You may consider is_readable() instead. If the file exists but you cannot
read it, file_exists() will still return true. If the file does not exist
or you cannot read it, is_readable() returns false.
