Projects / DBG


DBG is a PHP debugger and profiler. It makes it much easier to discover the origins of problems and bugs in PHP scripts. It's equipped with the ability to backtrace errors. It shows local and global variables as well as parameters which have been passed to all nested function calls at any point of execution. Among other things, it allows you to execute scripts in a step-by-step manner, set breakpoints (including conditional ones), evaluate expressions, and watch variables. The profiler allows you to find bottlenecks in PHP code at the functions level as well as the modules level and even the source lines level.

    Release Notes: The build process was changed, so now dbg-cli depends on the system-provided getopt and regexp (if available). A fixed delay of 15 seconds is used if the PHP interpreter is not found. A possible crash when Apache shuts down was fixed.
