Ubuntu-16.04安装Xdebug-2.2.5及相关介绍

Xdebug是一个开放源代码的PHP程序调试器(即一个Debug工具)，可以用来跟踪，调试和分析PHP程序的运行状况。在日常开发中，我们会使用如 print_r() var_dump()等函数来进行调试，但毕竟Xdebug更加的专业，简单介绍下在Ubuntu-14.04下Xdebug-2.2.5的安装。

以上已经成功安装了Xdebug扩展，接下来还需要我们对php.ini配置文件就行一些修改。

接着执行下面命令，把编译好的扩展移动到php5目录中去

cp modules/xdebug.so /usr/lib/php5/20090626+lfs 将xdebug.so文件移到php5下面

//闻海南PHP博客 http://blog.phpha.com
phpha@asus:~$ sudo vim /usr/local/php/etc/php.ini
//添加以下配置选项，更多配置选项请自己借助查看官方说明
[Xdebug]
zend_extension = /usr/local/php/lib/php/extensions/no-debug-zts-20121212/xdebug.so
xdebug.auto_trace = on
xdebug.default_enable = on
xdebug.auto_profile = on
xdebug.collect_params = on
xdebug.collect_return = on
xdebug.profiler_enable = on
xdebug.remote_host = localhost
xdebug.remote_port = 9000
xdebug.remote_handler = dbgp
xdebug.trace_output_dir = "/usr/local/php/xdebug/"
xdebug.profiler_output_dir = "/usr/local/php/xdebug/"
