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.

To limit the size of client requests, the maxAllowedContentLength parameter can be modified in web.config, such as setting it to 104857600 (100MB), and synchronizing the maxRequestLength of ASP.NET at the same time; to reasonably set the connection timeout time, it can be modified through the IIS manager or appcmd.exe command, with the default of 120 seconds, and the API scenario is recommended to set it to 30-90 seconds; if the request queue is full, you can increase MaxClientConn and QueueLength, optimize application performance, and enable load balancing to relieve stress.

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.

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.

The core idea of integrating AI visual understanding capabilities into PHP applications is to use the third-party AI visual service API, which is responsible for uploading images, sending requests, receiving and parsing JSON results, and storing tags into the database; 2. Automatic image tagging can significantly improve efficiency, enhance content searchability, optimize management and recommendation, and change visual content from "dead data" to "live data"; 3. Selecting AI services requires comprehensive judgments based on functional matching, accuracy, cost, ease of use, regional delay and data compliance, and it is recommended to start from general services such as Google CloudVision; 4. Common challenges include network timeout, key security, error processing, image format limitation, cost control, asynchronous processing requirements and AI recognition accuracy issues.

When configuring dynamic compression in IIS, selecting content types reasonably can improve performance. First enable the dynamic compression module, install and configure web.config or IIS manager through the server manager. Secondly, set appropriate content types, such as HTML, CSS, JavaScript, and JSON, text content is suitable for compression, while pictures and videos are not suitable. Finally, pay attention to the impact of client compatibility and performance, monitor CPU load, client support status and small file compression effects, and adjust the configuration based on actual traffic to obtain the best benefits.
