same for php80.

in php74 the now fatal error was a deprecated warning:

PHP Deprecated:

I'm not familiar with this file and we do not have a port called "CFPropertyList". Where does the file come from? To find out if a MacPorts port installed it, run:

port provides /opt/local/lib/php/github/CFPropertyList/classes/CFPropertyList/CFBinaryPropertyList.php

If it says no port provides it, presumably you installed it yourself and you'll have to contact whoever developed it for a solution.

[ryandesign (Ryan Carsten Schmidt)]

Looks like you created this port yourself; you wrote to our mailing list asking for help developing it:

Not our bug.
