WampServer

I've installed "WampServer2.1d-x64" on a new Notebook "Windows 7 Pro 64 Bit". For a symfony project i need to install apc.dll.

what i've done:
- install wampserver with default settings on c:\wamp
- download apc
- copy apc.dll to the extension directory
- add extension=php_apc.dll to php.ini (both)
- activate php_apc in php extensions
- restart all services
- control over phpinfo()

result: phpinfo() don't show any apc.dll

apache_error.log:
PHP Startup: Unable to load dynamic library 'C:/Wamp/bin/php/php5.3.4/ext/php_apc.dll' - %1 is not a valid Win32 application

I tried all versions from [downloads.php.net], nothing has worked. Everytime the same error.

in the hope that someone can help me

Exact same problem here... (wampserver 2.1, Windows 7 Enterprise 64 bit)

Initially both php_intl.dll and php_apc.dll failed to load but solved part of the problem by copying *88.dll to apache bin folder... Reference this post for php_intl.dll fix... [forum.symfony-project.org]

Have tried countless version of the dll but same error...

Was unable to get wampserver 2.1 to work with any version of the php_apc.dll, even tried wampserver64...
I installed Easyphp (5.3.6.0)... Copied the php_apc.dll file to C:\EasyPHP\php\ext folder, uncommented the php_intl.dll and restarted...

Everything working now...

I still prefer wamp so will wait for a fix before re-installing...

Solution:

I tried also to install php_apc-3.1.5-5.3-vc9-x86 on WampServer2.1d-x64.

There is a CPU mismatch : x86 vs x64. Dependency Walker can be used to check this :
php_apc.dll is compiled for x86, as indicated in the package name.

Either you install WampServer in x86 or you install APC in x64.

The archive pecl-5.3.4-Win32-VC9-x64.zip contains APC and Memcache
Download here : [www.anindya.com].

Also, I had awful performances with APC and WampServer x64,
I switched both to x86 and everything is 'flying' as expected.

There is also a mismatch possibility in addition to the Win32 vs. x64 versions.

The compiled library must match the PHP distribution in terms of compiler, and thread-safety. Compiler possibilities are VC6 or VC9, thread-safe or non-thread-safe.

These are for precompiled versions downloaded. Otherwise, you have to build the library from source, paying careful attention to the compiler settings used in the build.

Hi Noranti,

Try these version and steps :

php_apc.dll
This is because you are missing a file.
Step 1. You can download [dllcentral.com] here.
Step 2. Paste this file into your system32 and system folder. Also put it in your syswow
Step 3. Navigate to your System32(32Bit OS) or SyWOW64(64Bit OS) Folder.
Note: The location of System32 or SyWOW64 is
C:Windows\System32 (If you are using 32Bit Windows)
C:\Windows\SysWOW64 (if you are using 64Bit Windows)
Step 4.Paste the php_apc.dll into this folder.
Step 5.Run the game. It might work now.
