Compiling a PHP extension for windows - php

I've previously managed to get XHP compiled in a Linux environment with the .so extension. I'm trying to compile it for use in a windows enviroment (.dll) and I've followed the following tutorial on php.net but after I buildconf, I fail to see the extension under configure --help (I downloaded the source at put the source folder in ext directory). Any help would be appreciated.
I'm using Visual studio 2008 and looking to compile extension for PHP 5.4.

XHP doesn't have a config.w32 file to support the Windows build environment (see Build for Windows.
Windows uses a different build system than Linux so it requires a different config. I remember manually converting a config.m4 to a config.w32 for a tutorial on how to write your own PHP extension and it was relatively painless. It could have been that way because it was simple compared to XHP's config.m4.
It wouldn't hurt to copy the contents of config.m4 to config.w32 and try to build it to see what happens.

Compiling a php extension into a dll

I've been attempting for a last few days to make use of the operator overloading extension (pecl.php.net/package/operator), which has apparently been updated recently to be compatible with 5.3 and 5.4.
I've tried compiling it in windows (64-bit Windows 7) using this guide, with PHP 5.4 and Windows SDK 7.1 without luck. So I tried doing it with PHP 5.3 and Windows SDK 6.1 and I can get it to successfully compile with the config "configure --disable-all --enable-cli --enable-operator" and then "nmake". The problem is that it doesn't produce a dll file for the operator extension, instead what I get is this, which is apparently useless for me. What I want is a dll I can use for my local WampServer setup.
I had had fatal errors when trying to use operator-0.4.1 from the pecl.php.net site, so instead I downloaded and compiled from the git repository (github.com/php/pecl-php-operator), which is what produced the .obj, .idb and .sbr files.
You have to do
configure --disable-all --enable-cli --enable-operator=shared
otherwise it's statically compiled.
Anyway, if you want to use it with WampServer, the binary will probably not work because if I'm not mistaken WampServer is compiled against the VC10 C runtime library, while the guide you linked to instructs you to use Visual Studio 2008 (which comes with VC9). You'll need to use the VC10 compiler (I think it's bundled with Windows SDK 7.1, so you can download just that and skip Visual Studio).
Into extension root path, and modify config.w32
EXTENSION('redis', sources); to EXTENSION('redis', sources,true);
buildconf --force
configure --enable-xx
nmake
you'll get php-redis.dll

Phpize under Windows

I'm trying to follow the instructions here: https://code.google.com/p/php-sweph/wiki/build to compile a PHP extension. My OS is Windows XP.
I'm unable to find "phpize" to do the command. However, I've installed Pear for PHP. is it something only for Linux or is there a way to compile with phpsize with Windows?
In windows compile script design to compile php itself and should add your extension to compile with php ...
On Windows, you don't call phpize but instead you call buildconf.bat.
Open a Visual Studio developer command prompt (either 64 or 32 bit),
and run
cd C:\php-src buildconf.bat --add-modules-dir=C:\MyPhpExtensions
buildconf.bat will scan each subfolder of C:\MyPhpExtensions looking
for config.w32 files.
It will then generate a configure.bat.

Compile an extension on Windows
It's hard to build PHP extensions on Windows yourself.: You need a PHP build environment on Windows, which means you need Visual Studio and some other things. See http://php.net/manual/en/install.windows.building.php for more information.
It's probably the easiest way to simply use Linux (or a Linux Virtual Machine), or get a pre-built .dll file form someone else.

Compiling a PHP extension as non-thread-safe

I am trying to compile the imagemagick (imagick) extension to use in a non-thread-safe environment on windows.
I am using PHP 5.3.10 and have set up Visual C++ express as my compiling environment.
The problem is that I am using a non-thread-safe version of PHP as a FCGI module in Apache 2.2.
Thus, my PHP is supplied with a php5.lib and not a php5ts.lib. I believe this is the reason why I am getting these errors:
imagick.obj : error LNK2019: unresolved external symbol __imp__tsrm_mutex_alloc referenced in function _zm_startup_imagick
I have only ever built and compiled things on linux, so am not too sure how to do this on a windows environment.
How can I compile the extension so that it is non-thread-safe?
I downloaded the threadsafe binary of PHP 5.3.10 to get a copy of php5ts.lib. I was then able to compile the extension.
I am guessing that setting the ZTS preprocessor directive to either 1 or 0 would cause the extension to compile as either threadsafe or non-thread-safe. (Not too sure about this, so if someone could let me know if this is correct or not, it would be much appreciated. :) )
I then set up a virtual machine running Windows 7 and installed the latest version of WAMP. Reason being that it used a threadsafe version of PHP.
I placed the dll in the ext folder in the PHP installation and enabled it in php.ini. However, even after trying both the ts and nts version in WAMP, I would get:
PHP Warning: PHP Startup: Unable to load dynamic library 'c:/wamp/bin/php/php5.3.10/ext/imagick.dll' - The specified module could not be found.
in Unknown on line 0
But the thing is that c:/wamp/bin/php/php5.3.10/ext/imagick.dll' does exist, and yes I have checked this a lot of times.
I then downgraded ImageMagick to 6.6.2-10-Q16, but still see the same problem.
The same issue occurs on my dev machine running a nts version of PHP 5.3.10 on Apache 2.2 (all installed manually).
Looks like I could be wrong regarding the ZTS preprocessor. If I set ZTS=0 and compile, using dependency walker on the compiled dll still shows that it requires php5ts.dll which is only present on threadsafe versions of PHP.
I did more tinkering with dependency walker and found that I had to statistically link to msvc100d.dll. I then removed ZTS in the preprocessor definition and was able to compile using php5.lib instead of php5ts.dll. I think this should get me a non-ts dll.
However, when loading the extension, I am still getting:
PHP Warning: PHP Startup: Invalid library (maybe not a PHP library) 'imagick.dll' in Unknown on line 0
And errors from dependency walker:
Error: At least one module has an unresolved import due to a missing export function in an implicitly dependent module.
Error: Modules with different CPU types were found.
Warning: At least one delay-load dependency module was not found.
Warning: At least one module has an unresolved import due to a missing export function in a delay-load dependent module.
Installed visual c++ express 2008 and compiled using platform toolkit v90, but still facing the same issues.
Any tips appreciated :)
Solution Found! See my answer.
Got it! I hope this can help those compiling php extensions on windows in the future. What I have done is based on: https://wiki.php.net/internals/windows/stepbystepbuild
Note: I read an answer on this site that said compiling PHP extensions by itself on windows is unsupported. Based on my experiments yesterday, it seems to be a lot of work as well, so I am using the PHP build process.
The best way is to use the PHP build process.
Install Visual C++ Express 2008 (any version will do, but express is free) and Windows SDK 6.1 (note that we want the 6.1 version not anything older or newer).
Install the SVN client tools if you haven't done so and restart for your PATH variable to take effect.
Get the PHP SDK binary tools and extract it to C:\php-sdk.
Start the CMD Shell under Microsoft Windows SDK v6.1 in your start menu and run cd C:\php-sdk.
Run setenv /x86 /xp /release this creates a 32-bit release. You can use /x64 to build a 64-bit release (I have not tried this).
run bin\phpsdk_setvars.bat
run bin\phpsdk_buildtree.bat php53dev
Download the PHP source code and extract it to C:\php-sdk\php53dev\vc9\x86 so that you end up with C:\php-sdk\php53dev\vc9\x86\php5.3-xyz
Download the latest deps and extract everything to C:\php-sdk\php53dev\vc9\x86. You may be prompted to overwrite any existing folders, so press yes.
run cd C:\php-sdk\php53dev\vc9\x86
Check out the latest version of your extension from the svn repository: svn co http://svn.php.net/repository/pecl/imagick/trunk pecl/imagick I am checking out imagick here.
Install any dependencies. In my case, I need to install ImageMagick, so I downloaded the latest recommended windows binary. You will need to restart after installation to update your PATH variable, but you can do this after you have compiled. Make sure you install the C/C++ headers and includes as well.
Copy the contents of the includes directory from the ImageMagick install directory to C:\php-sdk\php53dev\vc9\x86\deps\include.
Copy the contents of the lib directory from the ImageMagick install directory to C:\php-sdk\php53dev\vc9\x86\deps\lib
Now, let's build: run cd C:\php-sdk\php53dev\vc9\x86\php5.3-xyz then buildconf then configure --help. Look at the help properly. It will show you all config flags and any avaliable extensions to enabled. In my case, since I added imagick, I had an option called --with-imagick
Run config: configure --enable-cli --with-imagick=shared --disable-zts If you want to build a non-thread-safe binary use --disable-zts, otherwise remove that configuration flag. I am not sure why, but sometimes extensions use the --with-myextension flag and sometimes --enable-myextension, so check configure --help for the flag to use. If you add =shared after the extension flag, it will be compiled as a separate DLL, which si what we want.
Compile: run nmake then nmake snap.
Done :) Check C:\php-sdk\php53dev\vc9\x86\php-5.3.10\Release (non-thread-safe) or C:\php-sdk\php53dev\vc9\x86\php-5.3.10\Release_TS (thread-safe). Your compiled binaries should be in there. The compiled extensions (pecl), should be in a ZIP file similiar to pecl-5.3.10-nts-Win32-VC9-x86.zip. Open this file and extract the extensio DLL to your ext folder in your PHP installation.
Enable the PHP extension and restart your webserver. Run phpinfo() and check that the extension is enabled.
If the extension does not work properly, make sure you reboot to update your PATH variable. In my case, I need to have the imagemagick install directory in my PATH variable.
???
Profit!
Is there a reason you need to compile? Why not download? It's usually much simpler/quicker on Windows.

how to add extension in php Opensuse

I want to add an extension so I can use my own function in php for example my codes of C but I don't know the requisites and instructions of doing it.I have php5 and OS:Opensuse 11.
I don't know about configure and the codes in shell
there should be something like ext_skel so I can create config files but I don't have it should I download it from somewhere?
Due to this link http://www.tuxradar.com/practicalphp/20/3/0
there should be ext directory but I don't have it.
Thanks in Advance
cd
vi ext/util/config.m4a
./build conf --force
./configure => i don't know here
You should download PHP and then change to the ext directory and follow the tutorial. Don't forget to compile PHP too, because the extension you create depends heavily on the PHP version. I've installed OpenSuse but I don't think it does affect building a PHP extension. You might need some compiler tools etc. I found /php-5.2.6/ext/ext_skel in my PHP path. I've PHP installed in my home directory. You need to install the sources. In OS it's zypper in php5-devel. You can also download the tarball from the PHP site.
Edit: Here is another tutorial about php extension programming.

How do I compile an extension for PHP 5.3 for windows as a DLL?

I'm currently rewriting a PHP Extension that was originally written for PHP 4.2.2. My issue is having the build/compile process generate a .dll instead of compiling the extension into the PHP core. The environment is windows server 2003. I'm using Visual Studio 2008.
I used the EXT_SKEL script to generate the framework, and I can succesfully compile the extension into the php core. I'm trying to instead compile it as a .dll so I can easily distribute it to my clients. Can anyone point me in the right direction for how to tell the PHP 5.3 build process that i'd like to compile my extension as a .dll instead of staticly into PHP itself?
To build the extension's framework I run:
php.exe ext_skel_win32.php --extname=myextension --proto=myprototypefile.dat
Modified config.w32 to uncomment the 'ARG_ENABLE' line and make the default enabled
buildconf.bat
cscript /nologo configure.js
nmake
I confirm that I can run the extension's methods from within PHP, however it does not produce a distributable .dll. instead it compiles the methods into the PHP binary. Can anyone point me in the right direction?
Try
configure.js --enable-myextension=shared
edit: might also be
configure.js --with-myextension=shared
