Comment (by olly):

 I'm testing with PHP 7.1 and `/usr/bin/php7.1 -m` shows me:

 {{{
 $ /usr/bin/php7.1 -m
 [PHP Modules]
 calendar
 Core
 ctype
 date
 exif
 fileinfo
 filter
 ftp
 gettext
 hash
 iconv
 json
 libxml
 openssl
 pcntl
 pcre
 PDO
 Phar
 posix
 readline
 Reflection
 session
 shmop
 sockets
 SPL
 standard
 sysvmsg
 sysvsem
 sysvshm
 tokenizer
 Zend OPcache
 zlib

 [Zend Modules]
 Zend OPcache

 }}}

 However, `make check` in the source tree runs the testsuite like so:

 {{{
 php7.1 -n -d safe_mode=off -d enable_dl=on -d extension_dir=.libs -d
 include_path=php7
 }}}

 The `-n` tells it not to load the default config files, and in that mode
 no "Zend Modules" are loaded:

 {{{
 $ /usr/bin/php7.1 -n -d safe_mode=off -d enable_dl=on -d
 extension_dir=.libs -d include_path=php7 -m
 [PHP Modules]
 Core
 date
 filter
 hash
 libxml
 openssl
 pcntl
 pcre
 Reflection
 session
 SPL
 standard
 zlib

 [Zend Modules]

 }}}

 And in the PHP 7.1 config, I can see that "opcache" is loaded by default
 but no others are, which matches the output above:

 {{{
 $ rgrep -i zend_extension /etc/php/7.1
 /etc/php/7.1/mods-available/opcache.ini:zend_extension=opcache.so
 }}}

 So it seems to me that Debian's PHP 7.1 loads the opcache Zend extension
 (and no others) by default, but that Xapian's bindings don't need this, as
 the tests are run without it by default anyway.

 What Zend extensions do you think are needed, and what evidence do you
 have for that?
