As of my last knowledge update in September 2021, "php-opencv" is not a specific package or extension available for PHP on Windows. However, you can use the OpenCV library with PHP on Windows by leveraging a PHP extension called "php-opencv" or "php-opencv-bindings."

To use OpenCV with PHP on Windows, you can follow these general steps:

  1. Install OpenCV Library:

    • Download and install the OpenCV library for Windows from the official OpenCV website (https://opencv.org/releases/).
    • During installation, ensure that you add OpenCV to the system PATH so that PHP can find the necessary libraries.

  2. Install PHP Extension:

    • Download the appropriate version of the "php-opencv" or "php-opencv-bindings" extension that matches your PHP version and system architecture (32-bit or 64-bit).
    • Make sure to get the extension compatible with your PHP version and build type (thread-safe or non-thread-safe).
    • Place the extension file (DLL) in the PHP extensions directory (e.g., "ext" folder within your PHP installation).

  3. Configure PHP:

    • Open the PHP configuration file (php.ini) in a text editor.
    • Add the following line to enable the "php-opencv" extension:
      makefile
      extension=php_opencv.dll

  4. Restart Web Server:

    • Restart your web server (e.g., Apache, Nginx) or the PHP development server if you are using it.

  5. Verify Installation:

    • Create a PHP file with the following code to verify if the extension is installed correctly:
      php
      <?php
      
phpinfo();
      
?>
    • Open the PHP file in a web browser and search for "OpenCV" in the output to confirm that the extension is loaded.

Please note that the availability and installation process of the "php-opencv" extension may vary, and the above steps are general guidelines. Ensure that you download the extension from a trusted source and verify its compatibility with your PHP version and system configuration.

Keep in mind that the information provided here might become outdated, as software and packages evolve over time. For the latest and most accurate installation instructions, refer to the official documentation and resources related to the "php-opencv" extension or any specific PHP OpenCV bindings you plan to use.
