Question

我正在使用Intl库来格式化带有货币符号的数字。

$number = new NumberFormatter('es_ES', NumberFormatter::CURRENCY);
echo $number->format('234234.234324');

我的本地php版本：

version 1.1.0
ICU version 50.1.2
ICU Data version    50.1

服务器

version 1.1.0
ICU version 50.1.2

结果：
我的版本：234.234,23€
服务器版本：€234.234,23

货币符号应位于数字的末尾，而不是位于数字的开头

Answer 2

Plesk用PHP 7.1安装的intl扩展名存在完全相同的问题。

$ /opt/plesk/php/7.1/bin/php -a
Interactive shell

php > $a = new \NumberFormatter("es_ES", \NumberFormatter::CURRENCY);
php > echo $a->format(12345.12345);
€ 12.345,12

与/opt/plesk/php/7.1/bin/php -i一起使用的是那些正在使用的ICU版本：

version  => 1.1.0
ICU version  => 4.2.1

要解决此问题，我必须从源代码中编译较新版本的ICU（我能够无错误编译的最新版本是58.2），然后还使用源代码从源代码中为我的PHP版本编译了intl扩展名。 ICU（因为我使用的是Plesk，PHP的二进制文件就是它使用的二进制文件）：

wget http://download.icu-project.org/files/icu4c/58.2/icu4c-58_2-src.tgz
tar xzvf icu4c-58_2-src.tgz
cd icu/source/
CXXFLAGS="-std=c++0x" ./runConfigureICU Linux --prefix=/opt/icu4c-58_2
make
sudo make install

cd ../../

wget http://php.net/distributions/php-7.1.22.tar.gz
tar xzvf php-7.1.22.tar.gz
cd php-7.1.22/ext/intl
/opt/plesk/php/7.1/bin/phpize
./configure --with-php-config=/opt/plesk/php/7.1/bin/php-config --enable-intl --with-icu-dir=/opt/icu4c-58_2
make
sudo make install

然后确保已加载扩展名，在我的情况下为/opt/plesk/php/7.1/etc/php.d/intl.ini：

; Enable intl extension module
extension=intl.so

然后重新启动或重新加载httpd，Apache，PHP-FPM或正在加载PHP的内容：

sudo service httpd restart

/opt/plesk/php/7.1/bin/php -i现在显示的版本：

version => 1.1.0
ICU version => 58.2
ICU Data version => 58.2

现在正确显示了货币：

$ /opt/plesk/php/7.1/bin/php -a
Interactive shell

php > $a = new \NumberFormatter("es_ES", \NumberFormatter::CURRENCY);
php > echo $a->format(12345.12345);
12.345,12 €
