• 下载XAMPP集成开发环境[我下载的版本：5.6.30]，安装后的路径为/Applications/XAMPP
• XDebug下载地址：http://www.xdebug.org/download.php
• 下载源码自行编译，比如：xdebug-2.5.1.tgz

hanqunfengdeMacBook-Pro:XAMPP hanqunfeng$ tar -zxvf xdebug-2.5.1.tgz
hanqunfengdeMacBook-Pro:XAMPP hanqunfeng$ cd xdebug-2.5.1

Cannot find autoconf. Please check your autoconf installation and the
$PHP_AUTOCONF environment variable. Then, rerun this script.

#因为不存在autoconf命令，所以进行安装
hanqunfengdeMacBook-Pro:xdebug-2.5.1 hanqunfeng$ brew install autoconf
