介绍
官网的我直接拿过来了
XHProf 是一个轻量级的分层性能测量分析器。 在数据收集阶段，它跟踪调用次数与测量数据，展示程序动态调用的弧线图。 它在报告、后期处理阶段计算了独占的性能度量，例如运行经过的时间、CPU 计算时间和内存开销。 函数性能报告可以由调用者和被调用者终止。 在数据搜集阶段 XHProf 通过调用图的循环来检测递归函数，通过赋予唯一的深度名称来避免递归调用的循环。
XHProf 包含了一个基于 HTML 的简单用户界面(由 PHP 写成)。 基于浏览器的用户界面使得浏览、分享性能数据结果更加简单方便。 同时也支持查看调用图。
XHProf 的报告对理解代码执行结构常常很有帮助。 比如此分层报告可用于确定在哪个调用链里调用了某个函数。
XHProf 对两次运行进行比较（又名 “diff” 报告），或者多次运行数据的合计。 对比、合并报告，很像针对单次运行的“平式视图”性能报告，就像“分层式视图”的性能报告

Libraries have been installed in:
/tmp/pear/temp/pear-build-defaultuserFBmoKa/xhprof-0.9.4/modules
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-Wl,--rpath -Wl,LIBDIR' linker flag
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

安装完后/usr/local/lib/php/目录下会有两个目录 xhprof_lib,xhprof_html/ xhprof_lib为工具的依赖目录，xhprof_html为web展示的项目目录，把xhprof_html 配置在Nginx server下 可以通过web地址的形式的方式访问
cp -r /usr/local/lib/php/xhprof_html/ /data/xhprof/
cp -r /usr/local/lib/php/xhprof_lib/ /data/xhprof/
Nginx配置
server{
server_name mydata.cn;
listen 80;
root /data;
index index.php;
autoindex on;
location / {
try_files $uri $uri/ /index.php$is_args$args;

编辑一个PHP文件测试
<?php
xhprof_enable(XHPROF_FLAGS_CPU + XHPROF_FLAGS_MEMORY);
for ($i = 0; $i <= 1000; $i++) {
$a = $i * $i;
}
$xhprof_data = xhprof_disable();
$XHPROF_ROOT = "./xhprof/";
include_once $XHPROF_ROOT . "/xhprof_lib/utils/xhprof_lib.php";
include_once $XHPROF_ROOT . "/xhprof_lib/utils/xhprof_runs.php";
$xhprof_runs = new XHProfRuns_Default();
$run_id = $xhprof_runs->save_run($xhprof_data, "xhprof_testing");
echo "<a href='http://mydata.cn/xhprof/xhprof_html/index.php?run={$run_id}&source=xhprof_testing'>goto</a>:http://mydata.cn/xhprof/xhprof_html/index.php?run={$run_id}&source=xhprof_testing\n";
运行php文件得到结果如下
