I'm currently trying to install the xhprof (PECL) extension onto my Mediatemple gridserver. I'm having a bit of a time of it since write restrictions won't allow the PECL installer to work. I've done the following:

mkdir /home/#####/data/lib/xhprof-0.9.2
wget http://pecl.php.net/get/xhprof-0.9.2.tgz
uncompress into /home/#####/data/lib/xhprof-0.9.2
cd ./xhprof-0.9.2/extension/
make install
make test
mkdir /var/tmp/xhprof

The compiler seems to run fine. make test returns 8success, 0 failure.

then I'm adding the following to my php.ini (at /home/#####/etc):

[xhprof] extension=xhprof.so

Note that I don't have access to the global php.ini file.

At this point, xhprof still doesn't work (ie - a call to xhprof_enable() returns a fatal error - undefined function)

Other specs: PHP Version 5.2.14 Apache/2.0.54 My questiosn: What is the proper php-config path? How do I tell php to parse my additional php.ini file?

Am I doing anything else wrong?

Thanks in advance for any help..


There is a nice guide on mediatemple wiki for setting up xhprof

Mediatemple has a hosting specific php.ini which you can use to setup.


I have met the same problem. But at last I solve it. This is because the Xhprof is not accurately loaded. If you run php -m which is used to show the extensions of PHP, you will find there is no Xhprof.

The steps which you install the xhprof is right, but maybe you chose a wrong php.ini file.

Maybe there are two files named php.ini, the one's location is /etc/php5/apache2/php.ini , and another's location is /etc/php5/cli/php.ini'. At first, some people may don't know where the php.ini is, so he write a file just named 'phpinfo.php' include a function 'phpinfo()' to find the location, and he enter the http://localhost/phpinfo.php at the broswer ,then glance over the page and find the 'Loaded Configuration File' is '/etc/php5/apache2/php.ini' ,so he add the [xhprof] into it.

But the '/etc/php5/apache2/php.ini' is for apache, and the '/etc/php5/cli/php.ini' is for client. So we should add the following to '/etc/php5/cli/php.ini' and just restart the apache.

Had the same problem.

I am using PHP5.6 so i could easily install XhProf using the following:

apt-get install php5.6-xhprof

Try something similar to your version of php.


probably it wasnt loaded. Check using "php -m"
