Comment (by carbonturtle):

 I encountered this issue this week when setting up a Laravel 7 (7.26.0)
 web app for the first time.  I only experienced the problem in a web
 server environment; I did not try to re-create it via command-line PHP
 execution.\\

 First I tried updating to 7.3.16_1 via `sudo port upgrade outdated` and
 reloading Apache, but this didn't fix it.\\
 \\
 Then I rebuilt php73-openssl with `sudo port -ns upgrade --force
 php73-openssl` and reloaded Apache, still no luck.\\
 \\
 '''Lastly, I tried `sudo port -ns upgrade --force php73 php73-openssl` and
 reloaded Apache and that did the trick.'''\\
 \\
 I don't know whether there were any MacPorts binaries involved before I
 forced the rebuild.  Is it MacPorts' default behavior to provide binaries
 when available?  I had assumed it was building everything from source.\\

 Note: A month ago, I encountered a problem (documented in ticket
 #[ticket:59837] "macOS 10.14 SDK does not appear to be installed even
 though Command Line Tools are installed") which I resolved by symlinking
 the 10.14 SDK as suggested in ticket:59837#comment:27. Mentioning it in
 case it's possible that the last time I upgraded php73* the build was
 somehow broken due to that issue.  That said, I use my local web server on
 an almost-daily basis and never encountered any problems with php73 before
 now.\\

 Many thanks to Ryan and the others for blazing this trail and saving me
 lots of time and frustration.
