Description:
------------
Note: The `Apache2 related` may or not may be entirely accurate; I don't know the scope of the issue.

After a recent re-install, I went to re-setup my Apache/PHP development server, and ran into problems with getting extensions to load properly. The following is set in my php.ini:

display_startup_errors = On
extension_dir = "./"
extension=php_curl.dll
extension=php_mbstring.dll
extension=php_mysql.dll

My path to php is `d:\program files\apache2\php5`.
My PATH environment variable has `d:\program files\apache2\php5` set in it.
PHP is being run as a module of Apache2.

I've tried numerous variations of extension_dir:
.
"."
.\
".\"
.\\
".\\"
./
"./"
d:\program files\apache2\php5\ext
"d:\program files\apache2\php5\ext"
d:\program files\apache2\php5\ext\
"d:\program files\apache2\php5\ext\"
d:\\program files\\apache2\\php5\\ext
"d:\\program files\\apache2\\php5\\ext"
d:\\program files\\apache2\\php5\\ext\\
"d:\\program files\\apache2\\php5\\ext\\"
d:/program files/apache2/php5/ext
"d:/program files/apache2/php5/ext"
d:/program files/apache2/php5/ext/
"d:/program files/apache2/php5/ext/"

Expected result:
----------------
The three extensions -- MBString, cURL, and MySQL -- load properly.

Actual result:
--------------
When Apache2 starts, I receive the following messageboxes:

"Warning"
PHP Startup: Unable to load dynamic library '*php_curl.dll' - The specified module could not be found.

"Warning"
PHP Startup: Unable to load dynamic library '*php_mysql.dll' - The specified module could not be found.

"Warning"
PHP Startup: Unable to load dynamic library '*php_curl.dll' - The specified module could not be found.

"Warning"
PHP Startup: Unable to load dynamic library '*php_mysql.dll' - The specified module could not be found.

* Represents any of the previously mentioned path variations.

Yes, I get each messagebox twice. So, cURL and MySQL are failing to load -- but MBString isn't?? I've verified there is only one copy of php_mbstring.dll on my computer -- the one in the /ext directory, right next to php_curl.dll and php_mysql.dll.

phpinfo() confirms that mbstring is loaded, but cURL/MySQL are not.

http://php.net/curl - Note to Win32 Users: In order to enable this module on a Windows environment, libeay32.dll and ssleay32.dll must be present in your PATH.

http://php.net/mysql - MySQL is no longer enabled by default, so the php_mysql.dll DLL must be enabled inside of php.ini. Also, PHP needs access to the MySQL client library. A file named libmysql.dll is included in the Windows PHP distribution and in order for PHP to talk to MySQL this file needs to be available to the Windows systems PATH.

Thanks for the timely and polite reply; following the instructions found in the manual worked -- my bad!

However, is there a way that the errors I experienced could be made to be less vague -- not that it's not finding php_*.dll, but more specifically a dependency of it?

I don't think it's possible. AFAIK Windows does not provide any information on this, so we got only the error message you see.

Alright then, I'll just have to make a note of this for next time.

Thanks :)
