Any chance of seeing your script ?

smbclient doesn't require the smb.conf and deprecated doesn't mean
'removed'. It takes quite some time before Samba removes deprecated
parameters, 'years' comes to mind.

That has been part of Samba since Sep 2018, could the libsmbclient that
libsmbclient-php uses require updating ?

It should be compiled in, because it is part of Samba. I think what
wasn't updated was the libsmbclient manpage, it appears that there is
an option not listed in the manpage 'min_proto'. Have a look here:
