Fatal error: Class 'NumberFormatter' not found
提问by cannatown
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.
我已经使用这个完全相同的代码多年了，我从来没有遇到过任何问题。现在突然它停止工作了。
I have read across the internet about this problem, and apparently you need PHP 5.3 or higherinstalled, and the PHP intlplugin installed. I have both of these, yet I am still receiving a Fatal error: Class 'NumberFormatter' not founderror whenever I use the following function:
我已经在互联网上阅读了有关此问题的信息，显然您需要PHP 5.3 or higher安装并PHP intl安装插件。我有这两个，但Fatal error: Class 'NumberFormatter' not found每当我使用以下功能时，我仍然收到错误：
function format_item($value)
{
$format = new \NumberFormatter('en_US', \NumberFormatter::CURRENCY);
return $format->formatCurrency($value, 'AUD');
}
Also, here is a snippit from my php.inifile showing that I have the PHP intlplugin installed:
另外，这是我的php.ini文件中的一个片段，显示我安装了PHP intl插件：
[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.dllin my php.ini, and it is also in my directory.
我也有extension=php_intl.dll我的php.ini，这也是我的目录。
Why am I getting this error?
为什么我收到这个错误？

This seems to be some really weird problem, and I somehow fixed it by doing the following:
这似乎是一些非常奇怪的问题，我通过执行以下操作以某种方式修复了它：
I upgraded my PHP in Wamp through thistutorial. I also updated my timezone in php.iniWhen I upgraded it didn't work, so I reverted back to my previous version of PHP, and voilà - it worked.
我通过本教程在 Wamp 中升级了我的 PHP 。我还更新了我的时区，php.ini当我升级时它不起作用，所以我恢复到我以前的 PHP 版本，瞧——它起作用了。
I have absolutely no idea how this solved the problem, however it worked for me.
我完全不知道这是如何解决问题的，但它对我有用。

YOu just need to enable this extension in php.ini by uncommenting this line: extension=ext/php_intl.dll
你只需要通过取消注释这一行来在 php.ini 中启用这个扩展：extension=ext/php_intl.dll

All you need is:
所有你需要的是：
apt-get install php7.0-intl
No need to change php.ini or do anything else. (Tested on PHP 7 on Ubuntu 16.04).
无需更改 php.ini 或执行任何其他操作。（在 Ubuntu 16.04 上的 PHP 7 上测试）。
The most up-voted answer here has you uncommenting a .dll which will never solve anything unless you are on a Windows server!
此处投票最多的答案是取消对 .dll 的注释，除非您在 Windows 服务器上，否则它将永远无法解决任何问题！
