Wamp, error PHP Startup: Unable to load dynamic library ‘c:/wamp/bin/php/php5.3.13/ext/php_intl.dll’

Tried to run internationalization in WAMP using php_intl module, but got error Unable to load dynamic library ‘c:/wamp/bin/php/php5.3.13/ext/php_intl.dll’. This makes me headache. It happens because Apache can’t find the icu*.dll files. There is at least 3 solutions:

• One solution is to add “C:\wamp\bin\php\php5.3.9” (or similar directory) to your system PATH.
• The other solution is to copy the icu*.dll files to your apache’s bin directory.
• A third option is to copy the icu*.dll files to your Windows system directory (system32 or SysWOW64).

Hope this helps anyone.
