[xdebug-general] Problem profiling PHP function and class definitions...

Hi,

Thanks for a great tool! Loads better than the alternatives.

My setup is as follows: PHP 5.1.2, IIS 5, Windows XP,
php_xdebug-5.1.1-2.0.0beta5.dll

I'm using xdebug to profile my php application, and I noticed something odd
in the "self" times of some of my scripts. It turns out that when file A
does a require_once() on a file B that contains only function and class
definitions, that the time spent loading the function and class definitions
is not added to the self time of file B, but to the self time of file *A*.

Now this is understandable if the classes are only actually loaded in script
A and not in script B. But there's more.

In my setup, script A loads script B. Script B loads script C. Script C has
class and function definitions. The time spent in C is added to B's self
time, not A's self time!

Is there something about the class loading of PHP that I don't understand?

Would it be possible to put entries in the profiles output for when a class
or function is defined?

Kindest regards,

Here's my example code for the A loads B example.

Example:

Test.php:

"""

<?php

    require_once("class.rss.php");

    require_once("class.user.php");

    require_once("class.details.php");

    require_once("class.folder.php");

    require_once("class.message.php");

    require_once("class.draft.php");

    require_once("func.elements.php");

?>

<wml>

<card title="title">

<p>

qzna!

</p>

</card>

</wml>

"""

All the class.*.php contain class definitions. The func.elements.php
contains function definitions. When I profile the above file, I get the
following output:

cachegrind.out.1072788529:
