Install

Compile in Linux

$ cd extension/
$ phpize
$ ./configure [--with-php-config=/path/to/php-config]
$ make && make install

edit php.ini, add a new line:

extension=xhprof.so

make sure it works:

php -m |grep xhprof

Profile your page

Add the following, as early as possible, to your initial PHP script:

xhprof_enable();

register_shutdown_function(
    function () {
        file_put_contents("/tmp/" . uniqid() . ".ApplicationName.xhprof", serialize(xhprof_disable()));
    }
);

Look at the results:

Make sure xhprof_html directory is reachable from your web application and reach the page xhprof_html/index.php to see a list of profiles.
