Self-hosted XHProf (free & opensource)

The original XHProf extension recently found new maintainers and adds PHP 7 & 8 support based on a completely rewritten code-base for less overhead.

You can install xhprof PHP Extension by compiling it from its open-source codes or from a package in your distribution. Head over to the Github repository and download the source from there. You can install the extension using these steps:

git clone "https://github.com/longxinH/xhprof.git"
cd xhprof/extension
phpize
./configure
make
sudo make install

Load the extension in your php.ini with extension=xhprof.so.

As for integration of XHProf into your application you can use the low-level API to enable and disable the Profiler:

<?php
xhprof_enable();

// your application code

$data = xhprof_disable();
file_put_contents(
    sys_get_temp_dir() . "/" . uniqid() . ".yourapp.xhprof",
    serialize($data)
);

This stores the trace in your temporary directory which the default UI uses to look for data. Install the xhprof_lib and xhprof_html directories from this repository into your webfolder and navigate to xhprof_html/index.php to see a list of trace.

If you want to use some improved open-source UIs take a look at the following projects:

• XHGui by Mark Story
• gajus/xhprof.io
• preinheimer/xhprof

Please check each projects installation notes on how to get the respective UIs running.
