Profiling with XDebug
---------------------


Edit ``/etc/opt/remi/php73/php.d/xdebug.ini`` and add those lines:

    .. code-block:: properties

        ; Enable xdebug extension module
        zend_extension=/usr/lib64/php/modules/xdebug.so

        xdebug.max_nesting_level=200

        xdebug.var_display_max_depth=3
        xdebug.profiler_enable_trigger=1
        xdebug.profiler_output_dir="/tmp/workspace/cachegrind"
        xdebug.profiler_output_name="cachegrind.out.%s.%r"

How to use it:

- When you add ``XDEBUG_PROFILE=1`` as a request parameter (e.g. ``http://..../?stuff&XDEBUG_PROFILE=1``) it will generate a profile info into  ``profiler_output_dir``
- With kcachegrind (on your host) you can analyse the generated trace and find hotspots
