WampServer

Hi everybody !

Who has not been confronted to those two error messages ?
"Unable to load dynamic library" ou "PHP can't load extension"

For those who would have this kind of problem, here is a list of possible causes with a valid solution for each one :

IMPORTANT : After any manipulation, don't forget to restart Apache service to take it into account.

------------------------------------------------------------------

- Extension is not activated in PHP configuration

Way 1 : From wamp menu => PHP -> Php extensions -> name of extension (ticked)

Way 2 : Open php configuration file* and search string extension=
=> Extension must be in extension list (if not, add it)
=> Extension must not begin with a semi-colon (comment)

------------------------------------------------------------------

- Extension path is incorrect

Open php configuration file* and search string extension_dir
=> Verify if path well exists
=> If path is not into quotes, add them

------------------------------------------------------------------

- Dll file does not exist

Go into folder containing extensions (cf extension_dir)
=> Verify that extension file well exists into this folder

------------------------------------------------------------------

- Dll file exists in several places (so in several versions)

Do a windows search for this .dll file
=> Rename all corresponding files which are not in extension_dir

------------------------------------------------------------------

- Extension version is up-to-date

Download the latest php version from site php.net/
=> Quit wampserver
=> Copy all dlls from root to folder bin/php/php_version/
=> Copy all dlls of folder ext to folder bin/php/php_version/ext
=> Relaunch wampserver

------------------------------------------------------------------

- Loaded configuration file is not the right one

Open url http://localhost/?phpinfo=1 and find field Loaded Configuration File
=> Verify if path is correct and correspond to your install path of wamp
(example : C:\wamp\bin\apache\apache2.2.8\bin\php.ini)

If precised file is incorrect
=> Delete this file if you don't need it
=> Add the environment variable* PHPRC which value will be the exact php.ini folder path

------------------------------------------------------------------

- Extension require other librairies to be installed

Example: sybase require two external librairies, available on their website.
=> You have to enquire to know if this librairy depends of another one...
=> Download required extensions, preferably with the same version

------------------------------------------------------------------

* Open php configuration file
Left click on wamp icon -> PHP -> php.ini (opened with notepad)


* Add a variable environment
Control Panel -> System (or Windows+Sleep)
In tab Advanced, click on button Environnement variables

In section System variables, click on New

Variable name : PHPRC
Variable value : correct path (without quotes) of the right php.ini file
(example for me : C:\wamp\bin\apache\apache2.2.8\bin\ )

Valid with Ok and restart computer to take this variable into account.
