Problem 1 - Installation request for php-amqplib/php-amqplib v2.7.0 -> satisfiable by php-amqplib/php-amqplib[v2.7.0]. - php-amqplib/php-amqplib v2.7.0 requires ext-bcmath * -> the requested PHP extension bcmath is missing from your system. Problem 2 - php-amqplib/php-amqplib v2.7.0 requires ext-bcmath * -> the requested PHP extension bcmath is missing from your system. - php-amqplib/thumper v0.5.0 requires php-amqplib/php-amqplib ^2.6 -> satisfiable by php-amqplib/php-amqplib [v2.7.0]. - Installation request for php-amqplib/thumper v0.5.0 -> satisfiable by php-amqplib/thumper[v0.5.0]. To enable extensions, verify that they are enabled in your .ini files: - /etc/php.ini - /etc/php.d/curl.ini - /etc/php.d/fileinfo.ini - /etc/php.d/json.ini - /etc/php.d/phar.ini - /etc/php.d/zip.ini You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.
It can be seen that you need to add Extends ext-bcmath.
1. Enter the following directory.
cd /usr/local/php/lib
2. Then execute the following code
yum install php-bcmath
to install successfully. Due to the problem in the above picture, you need to continue to install mbstring.
yum install php-mbstring
Press Enter to install successfully.
Finally solved the problem, then continue composer install, the operation is completed!

Composer provides advanced features, including: 1. Aliases: define convenient names for packages for repeated reference; 2. Scripts: execute custom commands when installing/updating packages, used to create database tables or compile resources; 3. Conflict resolution: use priorities Rules, satisfaction constraints, and package aliases resolve the different requirements of multiple packages for the same dependency version to avoid installation conflicts.

Answer: PHP microservices are deployed with HelmCharts for agile development and containerized with DockerContainer for isolation and scalability. Detailed description: Use HelmCharts to automatically deploy PHP microservices to achieve agile development. Docker images allow for rapid iteration and version control of microservices. The DockerContainer standard isolates microservices, and Kubernetes manages the availability and scalability of the containers. Use Prometheus and Grafana to monitor microservice performance and health, and create alarms and automatic repair mechanisms.

How to convert PHP array to object: use stdClass class, use json_decode() function, use third-party library (such as ArrayObject class, Hydrator library)

PHP code version control: There are two version control systems (VCS) commonly used in PHP development: Git: distributed VCS, where developers store copies of the code base locally to facilitate collaboration and offline work. Subversion: Centralized VCS, a unique copy of the code base is stored on a central server, providing more control. VCS helps teams track changes, collaborate and roll back to earlier versions.

Using Redis cache can greatly optimize the performance of PHP array paging. This can be achieved through the following steps: Install the Redis client. Connect to the Redis server. Create cache data and store each page of data into a Redis hash with the key "page:{page_number}". Get data from cache and avoid expensive operations on large arrays.

Answer: Use PHPCI/CD to achieve rapid iteration, including setting up CI/CD pipelines, automated testing and deployment processes. Set up a CI/CD pipeline: Select a CI/CD tool, configure the code repository, and define the build pipeline. Automated testing: Write unit and integration tests and use testing frameworks to simplify testing. Practical case: Using TravisCI: install TravisCI, define the pipeline, enable the pipeline, and view the results. Implement continuous delivery: select deployment tools, define deployment pipelines, and automate deployment. Benefits: Improve development efficiency, reduce errors, and shorten delivery time.

In order to maintain and update PHP web services and APIs, the following practices must be implemented: Update dependencies to ensure the latest security patches. Track codebase changes and collaborate on development with version control. Automated testing to verify updates do not impact functionality. Continuous integration ensures code validation through automated processes. Logging and monitoring help identify and resolve problems. Always update security patches to avoid vulnerabilities.

There are three main technologies for visualizing data structures in PHP: Graphviz: an open source tool that can create graphical representations such as charts, directed acyclic graphs, and decision trees. D3.js: JavaScript library for creating interactive, data-driven visualizations, generating HTML and data from PHP, and then visualizing it on the client side using D3.js. ASCIIFlow: A library for creating textual representation of data flow diagrams, suitable for visualization of processes and algorithms.
