"Unable to load dynamic library"
If you have this error, you have two solutions for this problem:
1) Copy all dll's from the php extensions directory (eg. c:\php\extensions) and set the extension_dir = ./ in your php.ini, or
2) In the php.ini set extension_dir = relative path from the php.ini (eg. c:\winnt) to the php extensions directory (eg. c:\php\extensions).
Example: extension_dir = ./../php/extensions
And now activate your extensions in the php.ini
Try php -m in line of commands, to verify if extensions are ok :-))
Notes:
The extension_dir path is like Unix path's (replace all \ to /)
In extension_dir, you simplest need the relative path from php.ini to php extensions
