Apache：无法加载动态库

Question

Apache 2.4.4 is not loading two modules. The modules exist in the directory where it is looking.

I'm using Windows 8.1, PHP 5.4.12, and a WAMPServer installation.

My PHP, Apache, and PostgreSQL are all 64 bit.

I added the directory (m:\\PostgreSQL\\9.3\\lib) that includes libpq.dll to my Path and then restarted but it didn't help.

I also tried copying libpq.dll into the Apache bin directory.

Are there any other dependencies?

Answer 1

我通过将 PostgreSQL bin 目录添加到路径（环境变量）来修复它。

Answer 2

for my case PHP 7.2.26 , it was under:

;;;;;;;;;;;;;;;;;;;;;;
; Dynamic Extensions ;
;;;;;;;;;;;;;;;;;;;;;;

on php.ini such that ;extension=pgsql becomes:

extension=pgsql
