This is not really PHP bug but just missing documentation.
(or I just couldn't find the place where it's documented :)

You can only put static scalars as the default value.

I couldn't find where this is documented either.

I am able to initialize member variables with strings using single or double quotes. Is a string a scalar?

Mainly, is there a way to initialize a member variable with a multi-line string? I think there should be.

Thanks

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.

"It is not allowed to use heredoc syntax in initializing class members. Use other string syntaxes instead." + example

P.S. You can initialize the member with multiline string with "first line \n second" or "first line
second".
