Comment (by ryandesign):

 Note to self: I encountered an unanticipated problem when trying to
 integrate OpenSSL support into the PHP SAPI subports directly. Old
 versions of PHP need old versions of OpenSSL. This need ought to be easy
 to satisfy by using the openssl portgroup since it puts the correct `-I`
 and `-L` flags for the requested version of OpenSSL before the `-I` and
 `-L` flags for the standard MacPorts include and library directories in
 the relevant environment variables. But building PHP fails at the link
 phase because the `-L` flags are in the wrong order. It turns out this is
 because PHP versions earlier than 8.3 don't honor user- (or
 MacPorts-)specified `LDFLAGS`. See https://github.com/php/php-
 src/pull/10678 and https://github.com/php/php-src/issues/11603 and
 https://github.com/php/php-src/pull/11605. I need to try backporting this
 fix.
