How to solve the issue - please install the “intl” extension for full localization capabilities

Question

What i Need

• I'm implementing currency symbol using symfony.
• I have referred this link : http://symfony.com/doc/current/components/intl.html.

The code i have implemented:

use Symfony\Component\Intl\Intl;

\Locale::setDefault('en');
$currencies = Intl::getCurrencyBundle()->getCurrencyNames();

$currency = Intl::getCurrencyBundle()->getCurrencyName('INR');

$symbol = Intl::getCurrencyBundle()->getCurrencySymbol('INR');

$fractionDigits = Intl::getCurrencyBundle()->getFractionDigits('INR');

$roundingIncrement = Intl::getCurrencyBundle()->getRoundingIncrement('INR');

Error:

The Symfony\Component\Intl\Locale\Locale::setDefault() is not implemented. Please install the "intl" extension for full localization capabilities.

Answer 1

You need just put one line to the terminal:

sudo apt-get install php5-intl

Answer 2

If you are using XAMPP on windows here is how:

open for example c:\xampp\php\php.ini and remove the semi colon ";" in front of "extension=php_intl.dll" save the file and restart apache.

That will get solve the error message.

Done.

Answer 4

When I tried to install intl on Ubuntu 16.04 with:

sudo apt-get install php5-intl

I've got an error like:

error: Unable to detect ICU prefix or no failed. Please verify ICU install prefix and make sure icu-config works. ERROR: `/tmp/pear/temp/intl/configure --with-php-config=/usr/bin/php-config --with-icu-dir=DEFAULT' failed

In order to solve the problem I needed to install:

sudo apt-get install libicu-dev

and after that install

sudo apt-get install php5-intl

That solved my problem.
