WAMP中没有postgresql server或db 下载具有postgresql server WAPP的本地服务器
您安装了库吗?正如Marco所说,您缺少PHP的ps postgreql插件(库),或者您没有在PHP配置中启用它。请删除PHP.ini中
extension=PHP\u pgsql.dll
行之前的注释,然后重新启动Web服务器questor似乎已手动将postresql添加到他的wamp设置中。我怀疑不涉及抛弃他所拥有的东西的答案会更受欢迎。
Call to undefined function pg_connect() in C:\wamp\www\newphp.php on line 18
