我正在 PHP Docker 容器中搜索 PHP 扩展的激活位置

Question

当我检查 php Docker 容器中激活的扩展时，输出列出了几个 PHP 模块，例如 Core、ctype、curl 等。但是，这些扩展在我的 php.ini 文件中显示为非活动状态。例如，

我的 Docker 文件

FROM php:8.1.25-apache-bullseye
WORKDIR /var/www/t3coredev

当我尝试激活 php.ini 中的“curl”扩展时，遇到错误：

PHP Warning:  PHP Startup: Unable to load dynamic library 'curl' (tried: /usr/local/lib/php/extensions/no-debug-non-zts-20210902/curl (/usr/local/lib/php/extensions/no-debug-non-zts-20210902/curl: cannot open shared object file: No such file or directory), 

我需要帮助才能找到这些扩展的正确激活位置。谢谢你。”

我知道您尝试在 php 脚本中使用“curl”函数

您需要在

docker-php-ext-install

指令中添加“curl”。来自您的 Dockerfile

FROM php:8.1.25-apache-bullseye
WORKDIR /var/www/t3coredev

#RUN git clone https://github.com/ImageMagick/ImageMagick.git /usr/local/src/ImageMagick \

RUN a2enmod alias \

完成后，你应该可以运行了

docker build . -t myimagetag

然后测试curl是否启用

docker run myimagetag php -r 'echo curl_exec(curl_init("https://dog.ceo/api/breeds/image/random"));'
