Chaching ( sound of light bulb turning on) I see that in the example in
the manual it needs to be compared to true ( a boolean value)
switch (true)
rather than switch ($line)
What is not apparent to me is why the first case matches if the preg
fails. Wouldn't line evaluate to true in a boolean context?
