Enable shmop extension for PHP to implement shared memory

In project development, if you want to realize the function of sharing data between multiple PHP processes and allow client connections to share a state, you need to enable the shared memory function shmop. If you anticipate encountering this need, it is best to add the --with-shmop option when compiling PHP. However, it was not added during compilation and can only be configured after recompiling.

1. Find the extension directory in the php source code package and enter shmop

# cd /usr/local/src/php-7.1.10/ext/shmop/

2. Execute phpize to generate the configuration

# phpize
[root@bogon shmop]# ls
acinclude.m4    build         config.h.in  config.nice    configure     CREDITS     libtool    Makefile.fragments  missing        package2.xml  README         shmop.la
aclocal.m4      config.guess  config.log   config.status  configure.in  include     ltmain.sh  Makefile.global     mkinstalldirs  package.xml   run-tests.php  shmop.lo
autom4te.cache  config.h      config.m4    config.sub     config.w32    install-sh  Makefile   Makefile.objects    modules        php_shmop.h   shmop.c        tests

3. Execute the command to start compilation

# ./configure --with-php-config=/usr/local/php/bin/php-config
# make && make install
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
----------------------------------------------------------------------
Build complete.
Don't forget to run 'make test'.
Installing shared extensions:     /usr/local/php/lib/php/extensions/no-debug-non-zts-20160303/

4. Modify php.ini to open the extension

Copy the returned line path:/usr /local/php/lib/php/extensions/no-debug-non-zts-20160303/

# vim /usr/local/php/etc/php.ini
;extension=php_pdo_sqlite.dll
;extension=php_pgsql.dll
extension=/usr/local/php/lib/php/extensions/no-debug-non-zts-20160303/shmop.so   //添加此行代码，后面跟上shmop.so

Restart php
