安装

This extension may be installed using the bundled version as of PHP 5.3.0, or as a PECL extension as of PHP 5.2.0. In other words, there are two methods to install the intl extension.

安装此 PECL 扩展相关的信息可在手册中标题为 PECL 扩展的安装章节中找到。更多信息如新的发行版本、下载、源文件、维护人员信息及变更日志等，都在此处： » https://pecl.php.net/package/intl.

Alternatively, --enable-intl will enable the bundled version while compiling PHP.

If your ICU is installed to a non-standard directory then you might want to specify its location in LD_LIBRARY_PATH environment variable so that dynamic linker can find it:

$ export LD_LIBRARY_PATH=/opt/icu/lib

Otherwise, if PHP and ICU are installed to their default locations, then the additional options to `configure' are not needed.

- open your php.ini file    c:/xampp/php/php.ini or search how to find it, it's up to your server.

- find for ;extension=php_intl.dll

- remove the comment ;

- restart the apache

- then it's working :) 



i used the same when i have problem in any extensions, open php.ini then search for the extension then remove the comment.

To install on windows uncommenting the dll in php.ini is not enough you also need to include several other libraries in your system path (not user path). Found these details here: http://stackoverflow.com/a/6086991/819883

OS : CentOS 5.10

PHP : 5.5.12

We tried installing via *pecl install intl* , but we were getting below warning in php error logs



PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/local/lib/php/extensions/no-debug-non-zts-20121212/intl.so' - /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.9' not found (required by /usr/local/lib/libicuio.so.55) in Unknown on line 0



Later we tried icu source from http://site.icu-project.org/download

Compile ICU ./configure --prefix=/opt/icu && make && make install 



And post which we compiled PHP via source with following configurations:

  --enable-intl

  --with-icu-dir=/opt/icu

On windows servers, open your php.ini (which should be in Program Files/PHP), and simply uncomment the extension.

extension=php_intl.dll

Restart IIS Webserver - done.

You need to install the library.



yum install libicu-devel



Will get it working with "pecl install intl"

On Fedora 18 "pecl install intl" wasn't working after "yum -y install icu" so I had to run "yum -y install php-intl" instead

I'm running on Mac OS X using a MacPorts install. According to this page, my vanilla version of PHP 5.3.5 from MacPorts should include the intl functions by default. As far as I can see from phpinfo(), the MacPorts version did not disable it. However, the functions aren't visible and don't work.



It seems to require an additional:



sudo port install php5-intl



After which everything bursts into life.
