Note the *single-quoted* double-quote in the error message.

No, he does not. The *main* error here is a *syntax* error. I have marked
the string literal in the statement above (as always, use a fixed-width
font), so that you can see the trailing <"> better.
Note the *escaped* double-quote in the string literal. Note where the
string literal starts and where it therefore ends, which syntax-highlighting
shows in any decent PHP editor (such as Eclipse PDT).
