xdebug

Xdebug is a widely used PHP extension that provides powerful debugging and profiling capabilities for PHP applications. It allows developers to step through code execution, inspect variables, set breakpoints, and analyze performance bottlenecks. This invaluable tool significantly simplifies the debugging process, reducing the time and effort required to identify and resolve errors. By enabling developers to gain deep insights into their code's behavior, Xdebug facilitates faster development cycles, improved code quality, and enhanced application performance. Common use cases include debugging web applications, API endpoints, command-line scripts, and unit tests, making it an essential component of many PHP development workflows.
