Xdebug Performance Analysis of PHP program

Here is only the Xdebug performance optimization (Xdebug can also be combined with other IDE breakpoint debugging, etc.), the detailed can refer to Xdebug's official site http://xdebug.org/

What is Xdebug?

Xdebug is an open source PHP program debugger (a debug tool) that can be used to track, debug, and analyze the health of PHP programs. (http://baike.baidu.com/view/1823486.htm)

Installation of Xdebug

PHP's integrated development environment Wampserver and XAMPP have been installed Xdebug, but may not be open, need to open to the php.ini, through the phpinfo can be learned whether the installation of Xdebug extensions;

Native PHP Environment (Win32 or Linux) how to install Xdebug,baidu or Google

Xdebug How to track performance

1 using Xdebug API xdebug_time_index () , specific reference http://xdebug.org/docs/basic

2 generate files, through tools to analyze, specific reference Http://xdebug.org/docs/profiler

There are two ways to generate files:

A a file is generated each time the program executes

b Generate files according to the Get/post/cookie parameter

Example: http://localhost/index.php? Xdebug_profile, note that you must capitalize here .

Cookie mode Firebug and chrome have plugins

Using this method, you need to set Xdebug.profiler_enable to 0 and turn on Xdebug.profiler_enable_trigger

Tools

Webgrind This is a browser-based PHP program, need to analyze the file is not many cases, can be very convenient to use

Wincachegrind Win32 Platform

Kcachegrindtool (Linux/windows, KDE)

My partial xdebug parameter (there are no write properties that have default values)

Zend_extension = "D:\xampp\php\ext\php_xdebug.dll"
Xdebug.profiler_append = On
Xdebug.profiler_enable = Off
Xdebug.profiler_enable_trigger = On
Xdebug.profiler_output_dir = "D:\xampp\tmp"
Xdebug.profiler_output_name = "cachegrind.out.-%s"
