　　经济学中有一条著名的80-20定律，引用到编程中，就是：80%的性能瓶颈是由20%的代码引起的。借助PHP的XDebug扩展，可以有效地找出这20%的代码。

　　一、安装配置
　　1、下载PHP的XDebug扩展，网址：http://xdebug.org/

　　2、在Linux下编译安装XDebug
引用
tar -xzf xdebug-2.0.0RC3.gz
cd xdebug-2.0.0RC3
/usr/local/php/bin/phpize
./configure --enable-xdebug
cp modules/xdebug.so /usr/local/php/lib/php/extensions/no-debug-non-zts-20020429/

　　注：/usr/local/php/lib/php/extensions/no-debug-non-zts-20020429/不同的PHP版本路径不同，也不一定要放在该路径，可以在zend_extension_ts中自行指定xdebug.so所在位置。
