User voice input is captured and sent to the PHP backend through the MediaRecorder API of the front-end JavaScript; 2. PHP saves the audio as a temporary file and calls STTAPI (such as Google or Baidu voice recognition) to convert it into text; 3. PHP sends the text to an AI service (such as OpenAIGPT) to obtain intelligent reply; 4. PHP then calls TTSAPI (such as Baidu or Google voice synthesis) to convert the reply to a voice file; 5. PHP streams the voice file back to the front-end to play, completing interaction. The entire process is dominated by PHP to ensure seamless connection between all links.

Packagist is Composer's default package repository for centralized management and discovery of PHP packages. It stores the metadata of the package instead of the code itself, allowing developers to define dependencies through composer.json and get the code from the source (such as GitHub) at installation time. Its core functions include: 1. Provide centralized package browsing and search; 2. Manage versions to meet dependency constraints; 3. Automatic updates are achieved through webhooks. While custom repositories can be configured to use Composer, Packagist simplifies the distribution process of public packages. The publishing package needs to be submitted to Packagist and set up a webhook, so that others can install it with one click through composerrequire.

To quickly get detailed information about a specific package in Composer, use the composershowvendor/package command. For example, composershowmonolog/monolog, which will display version, description, dependencies and other information; if you are not sure of the name, you can use some names to combine --platform to view platform requirements; add --name-only to simplify output; use -v to display more detailed content; support wildcard search, such as monolog/*.

When using Composer in a production environment, you need to pay attention to safety, stability and performance. 1. Use composerinstall-no-dev to reduce unnecessary development dependencies and reduce online environment risks; 2. Always submit and rely on composer.lock files to ensure version consistency, and avoid using updates during deployment; 3. Optional configuration platform-check=false ignores platform differences warnings, which is suitable for building packaging scenarios; 4. Enable APCU to accelerate automatic loading to improve performance, especially suitable for high concurrency services, while paying attention to namespace uniqueness to avoid cache conflicts.

Installing Composer takes only a few steps and is suitable for Windows, macOS, and Linux. Windows users should download Composer-Setup.exe and run it to ensure that PHP is installed or XAMPP is used; macOS users need to execute download, verification, and global installation commands through the terminal; Linux users operate similarly to macOS, and then use the corresponding package manager to install PHP and download and move the Composer file to the global directory.

Managing environment configuration in PHP projects can be achieved in a variety of ways. First, use the .env file of the Dotenv library to create configuration files for different environments such as .env.development and .env.production, and load them through vlucas/phpdotenv, and submit the sample files and ignore the real files; second, store non-sensitive metadata in the extra part of composer.json, such as cache time and log levels for script reading; third, maintain independent configuration files such as config/development.php for different environments, and load the corresponding files according to the APP_ENV variable at runtime; finally, use CI/C

PHP does not directly perform AI image processing, but integrates through APIs, because it is good at web development rather than computing-intensive tasks. API integration can achieve professional division of labor, reduce costs, and improve efficiency; 2. Integrating key technologies include using Guzzle or cURL to send HTTP requests, JSON data encoding and decoding, API key security authentication, asynchronous queue processing time-consuming tasks, robust error handling and retry mechanism, image storage and display; 3. Common challenges include API cost out of control, uncontrollable generation results, poor user experience, security risks and difficult data management. The response strategies are setting user quotas and caches, providing propt guidance and multi-picture selection, asynchronous notifications and progress prompts, key environment variable storage and content audit, and cloud storage.
