Introduction to installing xhprof for performance analysis in PHP 7.1

This article mainly introduces the introduction of installing xhprof for performance analysis in PHP 7.1. It has a certain reference value. Now I share it with you. Friends in need can refer to it

Install Extension
The xhprof extension version is obtained from https://github.com/longxinH/xhprof (a third-party library, the official version does not support php7)

Download and compile the xhprof extension
Operation in the html directory of the web:
git clone https://github.com/longxinH/xhprof

Compile extension

cd xhprof/extension/phpize ./configure makemake install

Modify php.ini configuration

[xhprof] extension=xhprof.so; xhprof.output_dir=/tmp/xhprof

xhprof.output_dir is the output directory of xhprof. Each time the save_run method of xhprof is executed, a run_id.project_name.xhprof file will be generated. It doesn't matter where this directory is. Note that the permissions of this path must be readable and writable! ! Otherwise, the file cannot be generated successfully

Restart php-fpm
sudo service php7.1-fpm restart

Add test code

save_run($xhprof_data, 'your_project');

Two files, xhprof_lib.php and xhprof_runs.php, need to be introduced into the test code

View the generated report
Required Visit: xhprof/xhprof_html/index.php file view:
http://localhost/xhprof/xhprof_html/index.php?run=5b35d3dfa8c29&source=your_project
The parameter after run is $run_id, and the source parameter is your_project configuration The name

If the graph is generated incorrectly, you need to install the plug-in:
sudo apt-get install graphviz

Actual demonstration code

'; } }// start profilingxhprof_enable(); test1(); // stop profiler $xhprof_data = xhprof_disable(); // display raw xhprof data for the profiler runprint_r($xhprof_data); include_once "xhprof_lib.php";include_once "xhprof_runs.php"; // save raw data for this profiler run using default // implementation of iXHProfRuns. $xhprof_runs = new XHProfRuns_Default(); // save the run under a namespace "xhprof_test" $run_id = $xhprof_runs->save_run($xhprof_data, "xhprof_test");echo "---------------\n". "Assuming you have set up the http based UI for \n". "XHProf at some address, you can view run at \n". "http:///index.php?run=$run_id&source=xhprof_test\n". "---------------\n";
