add xhprof to the installable pecl extensions about puphpet

[jtreminio]

This is actually already implemented: https://github.com/puphpet/vagrant-puppet-lamp/blob/master/modules/php/manifests/custom/xhprof.pp

The only way to get xhprof working with php 5.4 is to compile it in. This does everything necessary... I've simply never actually used xhprof.

Once it's installed, what process should I follow to get it working?

I prefer install xhprof over pecl, see e.g. http://queirozf.com/reminders/installing-xhprof-php-profiler-on-ubuntu

xhprof itself is just an profilling backend, so there is nothing more todo than install it over pecl and include/activate it via php.ini.

In case you also like to add a gui for it - which most people will probably need - you may also install http://xhprof.io/. To get it running you need to

• create a database for persisting the data
• define a database user
• clone the gui into a vhost/document root
• maybe create a dedicated vhost
• adjust the PDO config within the GUI tool

But at first, the GUI is not needed IMO.

Using pear xhprof will be installed in version 0.9.3 (just tested it on my 12.04 + PHP 5.4 machine). I think we should go this (out-of-the-box) way and not the manual installation way contained in the xhprof.pp.

you mean pecl not pear?

Oh of course. Had no coffee yet this morning :)

[staabm]

you should fix that ☕ :-)

Copy/paste this into a file:

<?php
$XHPROF_ROOT = "/var/www/xhprof";
include_once $XHPROF_ROOT . "/xhprof_lib/utils/xhprof_lib.php";
include_once $XHPROF_ROOT . "/xhprof_lib/utils/xhprof_runs.php";
// start profiling
xhprof_enable();
for ($index = 0; $index < 1000; $index++) {
    $x = array(1,2,3,4);
    array_reverse($x);
 }
//end profiling 
$xhprof_data = xhprof_disable();
$xhprof_runs = new XHProfRuns_Default();
$run_id = $xhprof_runs->save_run($xhprof_data, "foobar");

Open the file in your browser, then go here: http://192.168.123.101/xhprof/xhprof_html/index.php?

Change out with your specific IP address.

great, thanks

Have to reopen. xhprof integration currently does not work an a nginx machine properly. Do not know yet where the problem is caused.

[frastel]

php location for nginx is missing, so php pages are not interpreted.
