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.
Informație despre instalarea acestei extensii PECL poate fi găsită în capitolul manualului, întitulat Instalarea extensiilor PECL. Informații adiționale, cum ar fi lansări noi, descărcări, fișiere-sursă, informații despre persoana care întreține extensia și istoria schimbărilor poate fi localizată aici: » 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.
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.
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
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
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:
