Additional PHP does't work correctly

Hi,
I followed tutorial on https://www.howtoforge.com/tutorial/how-to-install-php-7-on-debian/ for Debian 9 and I compiled PHP 5.6, 7.0.x and 7.1.x versions. I can switch to another PHP version but some functions not work. For example curl, soap, file_get_contents functions complained about SSL until I add to php.ini this line:

Code:

openssl.cafile=/etc/ssl/certs/ca-certificates.crt

It was not necessary to add this on Debian 8.
Another problem is with imap functions. I still get this error:

Code:

Fatal error: Call to undefined function imap_open()

Another problem is with imap support. It doesn't work at all. When I try compile with "--with-imap --with-imap-ssl" than make throw error:

Code:

/usr/bin/ld: warning: libssl.so.1.1, needed by /usr/lib/x86_64-linux-gnu/libpq.so, may conflict with libssl.so.1.0.0

collect2: error: ld returned 1 exit status
Makefile:297: recipe for target 'sapi/cli/php' failed

This error is mentioned in discussion under tutorial but without solution. I need imap support for some projects so disabling imap support is no solution for me. Is there some way to use imap support with additional PHP?
Thanks
