基本特征 Basic Features

xdebug.default_enable = 1显示错误信息

1、性能分析 Profiling PHP Scripts in php.ini

开启性能分析： xdebug.profiler_enable setting = 1
日志文件输出目录： xdebug.profiler_output_dir = /data/log 通常是类似的文件 cachegrind.out.%p cachegrind.out.%t.%p

日志文件名：xdebug.profiler_output_name

xdebug.profiler_enable_trigger

You can also selectively enable the profiler with the xdebug.profiler_enable_trigger setting set to 1. If it is set to 1, then you can enable the profiler by using a GET/POST or COOKIE variable of the name XDEBUG_PROFILE. The FireFox 2 extension that can be used to enable the debugger (see HTTP Debug Sessions) can also be used with this setting. In order for the trigger to work properly, xdebug.profiler_enable needs to be set to 0.

函数：获取日志文件名 string xdebug_get_profiler_filename()

列名称含义

Self - Shows the execution time of the code in the current block

Cum. - Shows the total exuction time of functions that the current function (Self) calls

Avg vs. Total: Average is average time per call, Total is the total time spend in all calls.

2、代码覆盖率分析 Code Coverage Analysis

xdebug.coverage_enable = 1

函数检查是否开启 boolean xdebug_code_coverage_started() Returns whether code coverage is active.

Example:

<?php var_dump(xdebug_code_coverage_started());

xdebug_start_code_coverage();

var_dump(xdebug_code_coverage_started()); ?> 

3、函数调试 Function Traces

xdebug.auto_trace

xdebug.trace_output_dir

xdebug.trace_output_name Type: string, Default value: trace.%c

xdebug.show_mem_delta=1 显示内存

xdebug.collect_return=1 显示返回值

xdebug.trace_options =1 追加日志

string xdebug_get_tracefile_name() Returns the name of the function trace file
