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

UPDATED for new versions of PHP:

You can install intl extension for your current php version by this command:

sudo apt-get install php-intl

If you need to install php-intl not only for current selected PHP-version you can pass php version right after php word:

sudo apt-get install php7.4-intl    # for PHP version 7.4
sudo apt-get install php8.1-intl    # for PHP version 8.1

If you use Apache server with mod_php don't forget to restart it:

sudo apachectl restart

Original Answer

You need just put one line to the terminal:

sudo apt-get install php5-intl

Ok. Try do it more manually: pear channel-update pear.php.net pear upgrade PEAR pecl channel-update pecl.php.net pear install intl – Dratted

You need first to clean your other issues. Disable imap.so and try again. – Dratted

No matter your problem in life, there is always an apt-get install solution ;-) – Retrace

I have that installed, but it did not solve the problem – Dynamo

Package 'php-intl' has no installation candidate – Geehan

Answer 3

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 5

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.

Answer 6

Open XAMPP server. click on Apache config button And open php.ini file. Under php.ini file search intl And uncommented out the line. And restart the server. Hope this would be helpful.

Answer 7

For docker image php:5.6-apache this solved the problem for me

So I added these to my config:

  - run: sudo apt-get update
  - run: sudo apt-get install -y zlib1g-dev libicu-dev g++
  - run: sudo docker-php-ext-configure intl
  - run: sudo docker-php-ext-install intl

Answer 8

For docker with fpm it is:

FROM php:8.1-fpm

RUN apt-get install -y libicu-dev
RUN docker-php-ext-install intl
