Installing intl extension in XAMPP Fix “icuuc46.dll” file missing error

To install intl extension for php in XAMPP,

• Open [xampp_folder_path]/php/php.ini to edit.
• Search for

  ;extension=php_intl.dll

  and uncomment the line by removing semicolon.

• In [intl] section, uncomment and define default_local and error_level values.

  [intl]
  intl.default_locale = en_utf8
  intl.error_level = E_WARNING

• Save and exit the editior.
• In XAMPP control panel, restart the apache.

If you have the “icuuc46.dll” file missing error.

When I was trying to install intl extension for php in XAMPP version 1.7.7, I had this error saying that “icuuc46.dll” file is missing and need to install for intl extension to work. After I have read through some forums, it seems like it is a bug in this xampp version. Files are included in the package but in different locations. So simple copy and paste will solve this one. I would not move the files just in case there are some other dependency.

• Go to [xampp_path]/php/
• Select the following 3 files:
  1. icudt46.dll
  2. icuin46.dll
  3. icuuc46.dll
• Copy
• Paste the files in [xampp_path]/apache/bin folder.

Now we can go back to finish our own installation.  .
