I have installed XAMPP 1.7.4 on my server. I notice that the file php_apc.dll is not included in the distribution. On my developmentmachine I have XAMPP 1.7.3 installed, and APC works like it is supposed to. So I thought I could simply copy the php_apc.dll file to the php extensiondir on my server and add the extension in php.ini.

But when I do this I get an errormessage in my Apache error-log, and apc is not loaded.
The errormessage is:
"Unable to load dynamic library 'C:\\xampp\\php\\ext\\php_apc.dll' - The specified procedure could not be found.\r\n in Unknown on line 0"

Does anyone know what the issue might be?
And why isn't php_apc.dll not included in XAMPP 1.7.4 by default? Is there a problem?

Hope somebody can help. Thanks in advance!

The php_apc.dll version 3.1.3 in 1.7.3 is for php version 5.3.1 and so would not be compatible.

You could download this file:
php_apc-3.1.5-5.3-vc6-x86.zip
from here:
http://downloads.php.net/pierre/
which may be more compatible.

Just follow the procedure to include that you used with the one you copied from XAMPP 1.7.3.

I have no idea why it is not included in 1.7.4 or even in 1.7.5b1 - your guess.

Please let us know back if it was successful.

Good luck.

You could download this file:
php_apc-3.1.5-5.3-vc6-x86.zip

That worked! Thanks ALOOOT!!!

Do you know APC?
Do you want to use APC?

If any of this questions is "no", then you don't need this dll.

Hi dala,

This type of problem usually occurs when php_apc.dll is missing from your computer. This dll file can be downloaded from here.
http://dllcentral.com/php_apc.dll/5.2.5.5/
Download it and then extract the downloaded zip file to the Windows System32 folder, which is located in Windows Drive.
