MacGDBp

MacGDBp provides a graphical interface for live, interactive debugging of PHP applications running on macOS. It works with PHP that has the Xdebug extension enabled for remote debugging, allowing developers to pause execution at breakpoints and examine program state in real time.

The debugger offers traditional stepping controls—step in, step out, and step over—plus a continue command to run until the next breakpoint or program termination. Breakpoints can be set either by clicking a line number in a source file or by specifying a function or method name, giving flexibility for file‑line and symbolic stopping points.

During a session, the current call stack and source code are displayed, and variables at each stack frame can be inspected, including large arrays and objects. An expression evaluator lets users modify variable contents or invoke functions, and an inspector HUD reveals full variable values such as long strings or SQL queries. The project is stable, macOS‑only, and welcomes bug reports and contributions on Codeberg.
