What makes you think PHP will ignore the "\n"s? It does not.

To make the produced HTML source easier to read, most likely.
Although if they were concerned about readability they'd consider using single
quotes instead of doubles, and avoiding all those backslashes.
Maybe you're thinking of the fact that newlines aren't significant in HTML,
i.e. it won't force a new line in the rendered output. Nothing to do with PHP,
though.
