在專案開發中，想要實現PHP多個程式之間共享資料的功能，讓客戶端連線能夠共享一個狀態，需要開啟共享記憶體函式shmop。如果預期考慮會遇到這方面需求，那麼最好在編譯PHP的時候新增--with-shmop選項。但是編譯的時候沒有新增，只能在重新編譯配置了。
一、找到php原始碼包裡的擴充套件目錄，進入shmop
# cd /usr/local/src/php-7.1.10/ext/shmop/
二、執行phpize，生成配置
# 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
三、執行命令開始編譯
# ./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/
四、修改php.ini開啟擴充套件
複製返回的那行路徑：/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 //新增此行程式碼，後面跟上shmop.so
重啟php
