PHP : "intl" extension, Windows, Apache

PHP Internationalization support ("intl") is bundled as of PHP 5.3.0 and does not require PECL:
http://www.php.net/manual/en/intl.installation.php

Things to check if it does not work under Windows/Apache:

  1. php_intl.dll exists in the "ext" folder of the PHP root ( normally it's c:\Program Files\PHP\ext )
  2. The php.ini file in c:\Windows folder has these lines:
    extension_dir="C:\Program Files\PHP\ext"
    extension=php_intl.dll
    (php.ini in c:\Program Files\PHP may work too, but I keep it in Windows folder so it's not accidentally removed when PHP is upgraded)
  3. There are ICU .dll files in c:\Program Files\PHP:
    icudt*.dll
    icuin*.dll
    icuio*.dll
    icule*.dll
    iculx*.dll
    icutu*.dll
    icuuc*.dll
     (* is version number, for example icudt36.dll)
  4. c:\Program Files\PHP is in the %PATH% (environment variables in Control Panel - System - Advanced - ...)
    Without that, the ICU dlls are not loaded by PHP as Apache module - no error message is displayed, but the extension is not in the phpinfo().

    I use WampServer and the dll files where there, but PHP wasn't in my path directory. Thanks a lot, this article solved my problem.

    Also, my dll files had a 38 at the end (for version 3.8) and ICU versions go up to 4.8 now. So for step 3, don't do what I did and search by "icudt36.dll", search for "icudt", or perhaps .dll.

    @tjbourke: thanks for your comment. I replaced "36" with "*" in the post

    @b3wii : as long as the DLLs are in the %PATH%, Apache should load them. It will definitely load DLLs from it's own "bin" folder, so it's a possibility. Thank you for your comment!

    Make sure that the ICU is compiled with the same version of MSVC that PHP is.I had a problem with that the ICU was compiled with VC10 and PHP was with VC9.

    So althrough php -m and php -i detected the INTL it wouldn't show up in phpinfo(). When i got the ICU version right (that was compiled with VC9) it worked without a problem.

      Thanks Martin, could you please tell, which versions did you install? Was it PHP 5.4 or still 5.3? And which version of ICU.

      php -i and php -m show intl extension, but phpinfo() does not. I have this issue with php-5.4.22-Win32-VC9-x86.zip

      Where should I download ICU?
