I'm trying to setup a test server on my computer but getting errors in the Apache error log.

PHP Warning:  PHP Startup: Unable to load dynamic library 'C:\\php5\\php_gd2.dll' - The specified module could not be found.\r\n in Unknown on line 0
PHP Warning:  PHP Startup: Unable to load dynamic library 'C:\\php5\\php_mbstring.dll' - The specified module could not be found.\r\n in Unknown on line 0

httpd.exe: Could not reliably determine the server's fully qualified domain name, using 192.168.1.100 for ServerName

I have the server setup like this

C:/server
C:/server/apache
C:/server/php
C/server/www

I get an error in phpmyadmin saying unable to load mysqli too.
In the error log above it shows C:\\php5\\ I don't see any directories set to this location in either php.ini or httpd.conf

Please help.

What is your extension_dir (in php.ini) set to. Normally extensions are in the php/ext directory, not the root php directory.

; Directory in which the loadable extensions (modules) reside.
; http://php.net/extension-dir
; extension_dir = "C:/server/php/ext"
; On windows:
; extension_dir = "ext"

Those lines are commented. There should be a line somewhere below that were the extension directory is actually being set. By default it should be something like:

extension_dir="C:\php\ext"

Changed it but still getting an error

PHP Startup: Unable to load dynamic library 'C:/server/php/ext\php_pdo_sqlite.dll'

Should it not be loading like C:/server/php/ext/ext_folder?

Backslashes and forward slashes are interchangeable as far as PHP is concerned.

Locate your extension directory and make sure that those DLLs exist.

all the dll files are there trying to copy files in to the ext folders causes apache to stop.

all the dlls are in the main ext folder

any idea's?

If you do not have much experience in setting up servers, I would recommend you to use XAMMP from ApacheFriends
That should get you started for your Web development.

I ended up removing it all and trying xammp but that did not work either, I've installed plenty of testing servers on my computers in the past but never got anything like this. I'm using a laptop at the moment 64bit which has two directories which is new to me, I've had 64bit computers / laptops in the past but having a system for 32bit and 64bit within one was strange "two system folders". I figured it was causing issues.

I ended up trying easyphp which looks for free ports and it seemed to work, would have rather the full setup but can't be picky.

Thanks for the help.
