Fatal error: Class 'NumberFormatter' not found

Question

I've been using this exact same code for ages, and I have never had a single problem. Now all of a sudden it has stopped working.

I have read across the internet about this problem, and apparently you need PHP 5.3 or higher installed, and the PHP intl plugin installed. I have both of these, yet I am still receiving a Fatal error: Class 'NumberFormatter' not found error whenever I use the following function:

function format_item($value)
{
       $format = new \NumberFormatter('en_US', \NumberFormatter::CURRENCY);
       return $format->formatCurrency($value, 'AUD');
}

Also, here is a snippit from my php.ini file showing that I have the PHP intl plugin installed:

[intl]
intl.default_locale = fr_FR
; This directive allows you to produce PHP errors when some error
; happens within intl functions. The value is the level of the error produced.
; Default is 0, which does not produce any errors.
intl.error_level = E_WARNING

I also have the extension=php_intl.dll in my php.ini, and it is also in my directory.

Why am I getting this error?

Did you uncomment the extension from php.ini? Did you restart apache after you uncommented it? I found this, look at it and see if it helps you http://stackoverflow.com/questions/1451468/intl-extension-installing-php-intl-dll — Eric Martinez, May 31 '15 at 05:37
create `phpinfo.php` and in it put: `` then navigate to the page. Confirm your version and the extension are in-fact loaded. — Wade, May 31 '15 at 05:49
Some other useful debugging tools may be to look at your phpinfo and also looking at what extensions are actually loading with get_loaded_extensions. You can use php -i on the command line or phpinfo(). http://php.net/manual/en/function.phpinfo.php http://php.net/manual/en/function.get-loaded-extensions.php — iridian, May 31 '15 at 06:01
PHP is definitely working. I do not have those .dll files, so I downloaded the latest version to get the .dlls and put them in my directory. The latest version of PHP doesn't even have these .dlls, so how am I supposed to get them? — cannatown, May 31 '15 at 06:03
The currency code should be wrapped in quotes.. Should be `'AUD'`. Check the docs: http://php.net/manual/en/numberformatter.formatcurrency.php — Wade, May 31 '15 at 06:04
@WadeShuler it is in my file, for some reason it didn't paste them in the post. I will edit it — cannatown, May 31 '15 at 06:06
Do you have: `use NumberFormatter;` at the top of your file? If not, try removing the backslashes before `NumberFormatter` in the 2 places. Works both ways for me, no errors, but worth a shot. Other than that, I am out of ideas. If there is a newer version of PHP, upgrade to it and see. Maybe a bug with that version, or something went wrong with it. — Wade, May 31 '15 at 06:08
Neither of those things worked. I'm going to try upgrading wamp — cannatown, May 31 '15 at 06:10
So it happens that I already have the latest version of Wamp installed. What am I supposed to do now? — cannatown, May 31 '15 at 06:33

All you need is:

apt-get install php7.0-intl

No need to change php.ini or do anything else. (Tested on PHP 7 on Ubuntu 16.04).

The most up-voted answer here has you uncommenting a .dll which will never solve anything unless you are on a Windows server!

You just need to enable this extension in php.ini by uncommenting this line:

extension=ext/php_intl.dll

I am using PHP 5.5 version and got the same error in Ubuntu Machine. I have installed php5-Intl package and restarted my apache server. This resolved the issue.

For PHP5

sudo apt-get install php5-intl

For PHP7

sudo apt-get install php7.0-intl

For Mac OS X, use the following command for PHP5.6

brew install php56-intl

For different OS, checkout this page : http://php.net/manual/en/intl.installation.php

To check successful installation, run the command php -m. This should show the intl package in the list.

If you are using XAMPP in Mac OS X, php-intl will sometimes create different problems. You can follow the debug steps mentioned here

If you are facing Unable to load dynamic library '/usr/lib/php/extensions/no-debug-non-zts-20121212/intl.so' error, follow the steps as mentioned here

thanks. it has given me clue for solving the issue – Ariful Islam Apr 11 '22 at 17:01 — Ariful Islam, Apr 11 '22 at 17:01

This means that your intl package for PHP is not installed and/or not enabled.

Step 1

Make sure that you install php7.2-intl (or check that it is installed). In my case, I had PHP 7.2, but the version could change.

To install, I used

sudo apt install php7.2-intl

Step 2

After a successful installation, go to php.ini and enable that extension by removing the comment, as follows

extension=intl

Step 3

Retstart apache

sudo service apache2 restart

I am running on ubuntu-16.04 and I am using php7, I had the same issue, It is because of the php_intl extension

the way I fixed it-

First check the extension is installed or not on your server, use below command to check it
```
php -m | grep intl
```
If there's no results, you must need to install it

If not installed, let's install it

sudo apt-get update
sudo apt-get install php-intl

Finally you need to restart your web server after you install

If you are using Google App Engine, just add:

extension = "intl.so"

to your application's php.ini file.

outdated

On Max OS X with PHP installed with the Homebrew, we can:

We can check is module intl installed:

$ php -m

We can check module info:

$ brew info php72-intl

And install it with:

$ brew install php72-intl

This seems to be some really weird problem, and I somehow fixed it by doing the following:

I upgraded my PHP in Wamp through this tutorial. I also updated my timezone in php.ini When I upgraded it didn't work, so I reverted back to my previous version of PHP, and voilà - it worked.

I have absolutely no idea how this solved the problem, however it worked for me.

Solutions For ALL Windows and Mac.

Most of time this extension is not there, You just need to enable this extension in php.ini by uncommenting this line,

          extension=intl

if that line doesn't exists then add that line as like below in any place below first line,

         extension=intl
         extension=ext/php_intl.dll

for better result add below as like as well because with above one is in some scenario not working with only below one,

         extension=php_intl.dll

Then it look like this,

         extension=ext/php_intl.dll
         extension=php_intl.dll
         extension=intl

After That Mostly Don't Forgot to restart your server in my case I am using xampp otherwise the changes not working properly.

First of all, stop the XAMPP/Wamp and then kindly remove the starting semicolon ( ; ) from your xampp\php\php.ini the following code.

;extension=intl

And then restart your XAMPP/Wamp.

NOTE: For Windows, you can find the file in the C:\xampp\php\php.ini-Folder (Windows) or in the etc-Folder (within the xampp-Folder).

Very Important Note: "Close your Command Prompt And Restart Again" (It's very important because if you didn't restart your command prompt then changes will not be reflected.)

in case of using heroku/php you should add this to composer.json:
