» The full documentation
This section describes on how to install Xdebug.
» Basic Features
Xdebug's basic functions include the display of stack traces on error conditions, maximum nesting level protection and time tracking.
» Variable Display Features
Xdebug replaces PHP's var_dump() function for displaying variables. Xdebug's version includes different colors for different types and places limits on the amount of array elements/object properties, maximum depth and string lengths. There are a few other functions dealing with variable display as well.
» Stack Traces
When Xdebug is activated it will show a stack trace whenever PHP decides to show a notice, warning, error etc. The information that stack traces display, and the way how they are presented, can be configured to suit your needs.
» Function Traces
Xdebug allows you to log all function calls, including parameters and return values to a file in different formats.
» Code Coverage Analysis
Code coverage tells you which lines of script (or set of scripts) have been executed during a request. With this information you can for example find out how good your unit tests are.
» Profiling PHP Scripts
Xdebug's built-in profiler allows you to find bottlenecks in your script and visualize those with an external tool such as KCacheGrind or WinCacheGrind.
» Remote Debugging
Xdebug provides an interface for debugger clients that interact with running PHP scripts. This section explains how to set-up PHP and Xdebug to allow this, and introduces a few clients.
