    Who can do a lesson on installing Sitemap via Composer for a site on XAMPP? I can not find anything on the Internet on this topic. I tried to establish this sitemap but I could not, I did not have enough knowledge.

  2. Alen says

    COOL! I got my installation working. Thanks!

  3. Pablo says

    Hi, I have installed XAMPP version 7.2.1 and I can find the extension=php_openssl.dll, but I cannot find the extension=php_curl.dll in php.ini. Any ideas? Thanks

    1. Full Stack developer says

      Hello Pablo,

      I think you don’t need you enable curl with XAMPP version 7.2.1 because in xampp/php/php.ini there is already enabled extension=curl, please continue install composer set up and please let me know if you still face any issue.


  4. Alexander says

    This was very helpful. Thanks. However, it did not work when I removed the semicolon from “extension=php_openssl.dll” in the php.ini file. The installation of Composer failed. When I added it again, it worked.

      I’m glad it helped you. Happy coding.

  6. Awii says

    I followed all the steps you have mentioned, But still I am getting ‘composer is not recognised as an internal or external command’ ,I restarted my computer , checked environment variable PATH its showing correct, but still not working, can you please let me know if I am missing something and how to resolve this problem.

    1. Full Stack developer says

      Hello Awii ,

      Add C:\xampp\php to your PATH Environment Variable.

      Then Close your Command Prompt And Restart Again.

      It’s very important because if you didn’t restart you command prompt then changes will not be reflected.


      Try to to restart your computer and then both composer and php will work globally.

      Please check and let me know.

    So much information around – and regrettably, maybe unwittingly and unintentionally, misinformation, but this worked like a dream. Many thanks!.

    I got this error when I install composer:
    The Composer installer script was not successful [exit code 1].

    Script Output:
    The “” file could not be downloaded: php_network_getaddresses: getaddrinfo failed: No such host is known.
    failed to open stream: php_network_getaddresses: getaddrinfo failed: No such host is known.

    1. Vikas Kumar says


      Solution 1. Ensure you have net connectivity.

      Solution 2. PHP required a system restart to pick it up. So unsetting the environment variables and restarting allowed the Composer installer to retrieve the required files.

    Hi, I have tried to install composer but I am getting this error

    The Composer installer script was not successful [exit code 1].

    Script Output:
    The APPDATA or COMPOSER_HOME environment variable must be set for composer to run correctly

    1. Vikas Kumar says

      Got the same error, and fixed it with updating composer version.

      Try to do a
      composer self-update
      and then a
      composer clear-cache

  11. yawar says

    yes, very thanks.
    At the beginning of my installation, I encountered the following erorr:
    The PHP exe file you specified did not run correctly [exit code 1]:

    Because I’ve changed the ‘php.ini’ file many times
    Then I downloaded a default ‘php.ini’ file and changed it to the compiler
    And finally I could install Composer

    1. Vikas Kumar says

      Happy coding.
