This article mainly introduces Xhprof, a PHP performance testing tool, which has a certain reference value. Now I share it with everyone. Friends in need can refer to it

Xhprof is a PHP performance testing tool. The extension can only be installed under Linux environment.

First installation steps

Download the source code package of xhprof from the official website http://pecl.php.net/package/xhprof
tar -zxvf xhprof-0.9.4.tgz
cd xhprof-0.9.4
cd extensions
./configure --with-php-config=/usr/local/data/php/bin/php-config //Note here is your own php path
make
sudo make install
Modify php.ini
extension=xhprof.so
xhprof.output_dir="/vagrant_data/xhprof"
#Restart php-fpm
ps aux | grep php-fpm
Find the master process
kill -USR2 process number

Check whether phpinfo is successful

OK , after seeing it, it means that the installation has been successful. Next, do a test to see the effect.

The decompressed compressed package contains two folders, xhprof_html and xhprof_lib, which are used to display test results:

Then visit Just sample.php under the examples folder: 127.0.0.1/examples/sample.php.

Then visit 127.0.0.1/xhprof_html/index.php

##Click to transfer

The analysis results have been displayed on the interface, click [View Full Callgraph] to display An analysis picture

Requires installation

Displayed in the form of pictures. This result is because the test is relatively simple, but in actual development the results will be many and complex.

This kind of interface is not very friendly, I will study xhprof gui in the future
