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.

The steps to install PHP8 on Ubuntu are: 1. Update the software package list; 2. Install PHP8 and basic components; 3. Check the version to confirm that the installation is successful; 4. Install additional modules as needed. Windows users can download and decompress the ZIP package, then modify the configuration file, enable extensions, and add the path to environment variables. macOS users recommend using Homebrew to install, and perform steps such as adding tap, installing PHP8, setting the default version and verifying the version. Although the installation methods are different under different systems, the process is clear, so you can choose the right method according to the purpose.

The key to installing Go is to select the correct version, configure environment variables, and verify the installation. 1. Go to the official website to download the installation package of the corresponding system. Windows uses .msi files, macOS uses .pkg files, Linux uses .tar.gz files and unzip them to /usr/local directory; 2. Configure environment variables, edit ~/.bashrc or ~/.zshrc in Linux/macOS to add PATH and GOPATH, and Windows set PATH to Go in the system properties; 3. Use the government command to verify the installation, and run the test program hello.go to confirm that the compilation and execution are normal. PATH settings and loops throughout the process

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.

To check whether Composer is installed correctly, first run the composer--version command to view the version information. If the version number is displayed, it means that it is installed. Secondly, use the composerdiagnose command to detect configuration problems and ensure that the environment variables and permissions are normal. Finally, try to verify the functional integrity through the composerrequiremonolog/monolog installation package. If the vendor directory is successfully created and the dependency is downloaded, it means that Composer is fully available. If the above steps fail, you may need to check whether PHP has been installed globally or adjusted system path settings.

To install the Composer plug-in, please first confirm that Composer is installed and the composer.json file exists, and then follow the following steps: 1. Make sure that Composer has been installed and created composer.json; 2. Search and copy the required plug-in name on Packagist; 3. Use the composerrequirequire command to install the plug-in, such as composerrequiredealerdirect/phpcodesniffer-composer-installer; 4. Verify whether the plug-in is effective and check compatibility and configuration. Follow these steps to correctly install the Composer plug-in.
