Krumo: Structured information display solution for PHP

Hey, I am Kaloyan (but everyone seems to call me KT)

I am the author of Krumo, Wano, Asido and few other open-source projects which titles that end with an "o".

Here are few of the things I posted on my site lately:

krumo's Issues

Expand All / Collapse All

This has been a requested featured from the start: the ability to expand and collapse all the nodes in a Krumo report.

Instead of printing output, return it to a variable

I struggled with the idea of adding this feature when initially working on Krumo, and I decided not to include it:

I am not sure why would you need such thing... What's the benefit of doing this ? The "krumo dump" is a bunch of HTML code, so I don't see what help it would it be if ti is saved to a var - it is meant to be seen, to visualize the data you ra dumping.

Over the years I've seen more than enough places where this feature was requested, and usually this is the advice I would give:

Anyway, try output buffering - start it before calling Krumo and close it afterwards - and you will have the "krumo dump" in the buffer. Please note that the first dump also prints the references to the CSS skin, and it printes the JS code used to expand/collapse the dump nodes.

Adding such a feature is really easy with output buffering, and I am going to add it as part of the krumo class -- to make it easy for all people that need that to do it out-of-the-box instead of doing the output-buffering themselves.

Are we duplicating effort on Krumo projects?

I just found this repo via Google. I've been maintaining Krumo here:

https://github.com/mmucklo/krumo/releases

For quite some time now. We should team up and combine our efforts.

Print the dumps at the end of the page

It's been a valid complain that if Krumo is called in the middle of some opened HTML tag, that will break the output of both that tag and Krumo itself. This is from SourceForge.net comments:

For example when you are generating an image and need to evaluate something, you can't simply output it to the screen.

https://sourceforge.net/p/krumo/discussion/686810/thread/74217e3b/

One solution (that I already use in Wano) is to use register_shutdown_function() to dump the krumo output at the end of the output.

PHP 7.2 - count(): Parameter must be an array or an object that implements Countable

I'm getting this error on a new install of PHP 7.2. I'm getting it in phpmyadmin as well just fyi:

Warning: count(): Parameter must be an array or an object that implements Countable in var/www/html/iconcierge/shared/krumo/class.krumo.php on line 1132
Warning: count(): Parameter must be an array or an object that implements Countable in /var/www/html/iconcierge/shared/krumo/class.krumo.php on line 1133
Warning: count(): Parameter must be an array or an object that implements Countable in /var/www/html/iconcierge/shared/krumo/class.krumo.php on line 1146

it is coming from this block of code:

/**
* Render a dump for an object
*
* @param mixed $data
* @param string $name
*/
private static function _object(&$data, $name)
{
	?>
	<li class="krumo-child">

		<div <?php if (count($data) > 0) {?> onClick="krumo.toggle(this);"<?php } ?>
			class="krumo-element<?php echo count($data) > 0 ? ' krumo-expand' : '';?>" >

				<a class="krumo-name"><?php echo $name;?></a>
				(<em class="krumo-type">Object</em>)
				<strong class="krumo-class"><?php echo get_class($data);?></strong>
            <?php
                if( get_class( $data ) == 'Image' ){
                    echo '<img class=img-thumbnail src="' . $data->urlSecure . '" />';
                }
            ?>
            
		</div>

		<?php if (count($data))
		{
			self::_vars($data);
            
        
		} ?>
	</li>
	<?php
}

Namely the two calls to count($data).

Casting $data to an array causes more bugs. Ideas?

Only prints public methods and variables

This is exactly what I was looking for but was disappointed that it only prints public members of an object.. print_r and var_dump print the whole object. For instanced a dump of the Order object

krumo($this);
echo "<pre>";
print_r($this);	

Results in an empty set in krumo, but it's far from empty.

"How to display arguments name (variable name) in krumo listing"

This is from a request on SourceForge.net:

Right now, if you do krumo($_SESSION, $_GET, $_POST); you will get 3 listings but all will be displayed as "...(Array, x elements)". Instead of those ... I think it would be much more useful to have the name of the array.
Right now, it is very confusing trying to make out which is which.
Thank you!

Drop krumo.ini

The krumo.ini configuration is a remnant from the PHP4 days. It was created as a configuration solution that will operate the selection of the CSS skin and the URL used for the images in the stylesheets.

As of ed1a544 the external images for the stylesheets have been converted into "data-URI" statements. This made the %url% stylesheet hack useless, as well as the "[css] url=..." section of krumo.ini

Now what is left in krumo.ini is only the "[skin] selected=..." which points to what the selected skin is. This can be easily set by a static class property, e.g. krumo::$skin = 'blue';, and with that having krumo.ini is pointless.

Dropping krumo.ini will reduce the configuration hassle and the footprint of the library.

count(): Parameter must be an array or an object that implements Countable

I'm getting the following error in PHP 7.2:

Warning: count(): Parameter must be an array or an object that implements Countable in krumo::_object() (line 1156 of backdrop/modules/contrib/devel/lib/krumo/class.krumo.php).

The problem is this bit of code, as it assumes $data is either an array or Countable:

<div class="krumo-element<?php echo count($data) > 0 ? ' krumo-expand' : '';?>">
