sudo apt-get install php5-intl
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.
Information zur Installation dieser PECL-Extension finden sie im Kapitel Installation von PECL-Extensions. Zusätzliche Informationen wie neue Releases, Downloads, Quelldateien, Maintainerinformation und ein CHANGELOG finden Sie hier: » http://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
environment variable so that dynamic linker can find it:
Otherwise, if PHP and ICU are installed to their default locations, then the additional options to `configure' are not needed.
You need to install the library.
yum install libicu-devel
Will get it working with "pecl install intl"
On windows servers, open your php.ini (which should be in Program Files/PHP), and simply uncomment the extension.
Restart IIS Webserver - done.
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.
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:
