var-dump-server

var-dump-server [--host address] [--format fmt] [options]

var-dump-server starts a server that collects and displays variable dumps from PHP applications using the Symfony VarDumper component. Instead of dumping variables directly into the browser or console output, the application sends them to this centralized server for structured display.This approach keeps debug output separate from application responses, making it particularly useful for debugging API endpoints, AJAX requests, and command-line scripts. The server formats dumps with syntax highlighting and collapsible structures, providing a cleaner debugging experience than inline var_dump output.
