php - docker php gettext 不翻译

Question

我迫切需要找到 gettext 无法翻译的解决方案。我遵循了多个教程，但不知道为什么它不起作用。语言环境已安装，gettext 也已安装，已激活，已加载到 php.ini 中，但仍然无法正常工作。目前我正在尝试将英语翻译成捷克语。

Dockerfile

FROM php:7.4-apache
RUN apt-get update && apt-get install -y zlib1g-dev libicu-dev g++ locales gettext

RUN docker-php-ext-configure intl \
    && docker-php-ext-configure gettext \
    && docker-php-ext-install \
    intl \
    gettext
RUN sed -i -e 's/# en_US.UTF-8 UTF-8/en_US.UTF-8 UTF-8/' /etc/locale.gen && \
    sed -i -e 's/# cs_CZ.UTF-8 UTF-8/cs_CZ.UTF-8 UTF-8/' /etc/locale.gen && \
    dpkg-reconfigure --frontend=noninteractive locales && \
    update-locale LANG=en_US.UTF-8
ENV LC_ALL en_US.UTF-8 
ENV LANGUAGE cs_CZ:en_US:en
ENV LANG en_US.UTF-8 
RUN docker-php-ext-install pdo
RUN docker-php-ext-install pdo_mysql
RUN docker-php-ext-enable intl gettext
RUN a2enmod rewrite
RUN service apache2 restart
RUN apache2ctl restart
EXPOSE 80

应正确安装语言

$ locale -a
C
cs_CZ.utf8
C.UTF-8
en_US.utf8
POSIX

文件结构

index.php
│
locale   
│
└───cs_CZ.utf8
│   │
│   └───LC_MESSAGES
│       │   messages.mo
│       │   messages.po
│   
└───en_US.utf8
│   │
│   └───LC_MESSAGES
│       │   messages.mo
│       │   messages.po

cs 翻译中的 messages.po

#: index.php:42
msgid "HELLO_WORLD"
msgstr "Ahoj světe"

msgid "TEST_TRANSLATION"
msgstr "Testovací překlad"

messages.po是通过msgfmt生成的

index.php

$locale = 'cs_CZ.utf8';
$domain = 'messages';
setlocale(LC_TIME, "");
$results = putenv("LC_ALL=$locale");
if (!$results) {
    exit('putenv failed');
}

$results = setlocale(LC_ALL, $locale);
if (!$results) {
    exit('setlocale failed: locale function is not available on this platform, or the given local does not exist in this environment');
}

$results = bindtextdomain($domain, "locale/$locale");
echo 'new text domain is set: ' . $results . "\n";

$results = textdomain($domain);
echo 'current message domain is set: ' . $results . "<br>";

echo _("HELLO_WORLD");
echo "<br>";
echo _("TEST_TRANSLATION");

返回

new text domain is set: /var/www/html/locale/cs_CZ.utf8 current message domain is set: messages
HELLO_WORLD
TEST_TRANSLATION

还有其他方法可以调试 gettext 吗？我错过了什么吗？谢谢!

所以罪魁祸首是 LANGUAGE，因为 debian 首先查找这个变量，甚至在 LC_ALL 之前!

putenv("LANGUAGE=$locale");
