PHP installation extension pgsql

The php uninstall and then install PostgreSQL, at compile time and then php

./configure
--with-pgsql=/usr/local/programs/postgresql \
--with-pdo-pgsql=/usr/local/programs/postgresql
加上这就可以直接编译出带PostgreSQL扩展的php了
 php -m | grep pgsql

In order not to recompile php, you can use additional tools phpize.

1、进入php编译目录下的ext/pgsql/；
2、根据php安装路径执行/usr/local/php/bin/phpize ；
3、假如已经安装postgresql数据库；
4、运行./configure --with-php-config=/usr/local/php/bin/php-config
5、make && make install
6、修改php配置文件/usr/local/php-7.0.4/etc/php.ini，添加pgsql.so模块。
extension_dir = "/usr/local/php-7.0.4/lib/php/extensions/no-debug-non-zts-20151012"

extension=pgsql.so
extension=pdo_pgsql.so
重启php，检查phpinfo中是否有pgsql模块。
