The Internationalization extension (Intl) is a wrapper for the ICU library, a set of C/C++ and Java libraries that provide Unicode and Globalization support for software applications. It enables PHP programmers to perform UCA-conformant collation and date/time/number/currency formatting in their scripts.

To enable this extension add the following line to your php.ini file:


And then set the intl.default_locale and intl.error_level directives in your php.ini file. intl.error_level is optional.


intl.default_locale = en_utf8

intl.error_level = E_WARNING
