Windows下PHP Judy扩展安装求助：PHP SDK路径不明

Hey there! Let's walk through getting Judy Arrays set up on Windows step by step—since you're new to PHP, I'll keep this straightforward and easy to follow.

First, let's clarify: the PHP SDK is a toolkit for compiling PHP extensions. If you're trying to build the Judy extension from source, you must have downloaded and extracted this SDK at some point. Here's how to track down those folders:

Scenario 1: You Manually Downloaded the PHP SDK #

• If you grabbed the SDK zip from PHP's official resources and extracted it, the root folder of your SDK will have the directories you need:
  • The includes folder: This is where you'll place the judy.h header file
  • The lib (or sometimes library) folder: Drop your renamed libJudy.lib file here (note: some SDK versions use lib instead of library—check which exists in your setup)
• For example, if you extracted the SDK to C:\php-sdk, your paths would look like:
  • Includes path: C:\php-sdk\includes
  • Library path: C:\php-sdk\lib

Scenario 2: You're Using a Prebuilt PHP Environment (Like XAMPP/WAMP) #

If you didn't manually download the SDK and are using an all-in-one environment like XAMPP, you have two options:

1. Check your PHP installation directory:
   • Find your main PHP folder (e.g., C:\xampp\php for XAMPP)
   • Look for an include (singular) folder to place judy.h
   • Look for a lib folder to place libJudy.lib
2. Important note: Prebuilt environments often don't include the full PHP SDK. If you run into issues compiling the extension later, you'll need to download the SDK version that matches your PHP release.

Once you've got judy.h and libJudy.lib in the right spots, you're ready to compile the Judy extension:

• Launch the PHP SDK's command line tool (usually a batch file like phpsdk_buildtree.bat that comes with the SDK)
• Navigate to the Judy extension's source directory in the command line
• Run the standard PHP extension build commands: phpize, configure, then nmake (adjust commands if your setup uses a different build tool)
• After compilation, copy the resulting judy.dll file to your PHP's ext folder
• Open your php.ini file, add the line extension=judy, then restart your web server to activate the extension

If you still can't track down the SDK folders, try searching Windows File Explorer for php-sdk or includes—it might turn up the directory you extracted it to earlier.
