print_r as a collapsable tree? :P

PHP
1

Anyone ever hear of anything like this?

I would like to make a multi-dimensional array act like a collapsible tree, would this require me to do too much manual labor or is something already made? :stuck_out_tongue:

Also found this little nugget on PHP.net, its dirty but works out the box


	
function print_r_tree($data)
{
    // capture the output of print_r
    $out = print_r($data, true);

    // replace something like '[element] => <newline> (' with <a href="javascript:toggleDisplay('...');">...</a><div id="..." style="display: none;">
    $out = preg_replace('/([ \	]*)(\\[[^\\]]+\\][ \	]*\\=\\>[ \	]*[a-z0-9 \	_]+)\
[ \	]*\\(/iUe',"'\\\\1<a href=\\"javascript:toggleDisplay(\\''.(\\$id = substr(md5(rand().'\\\\0'), 0, 7)).'\\');\\">\\\\2</a><div id=\\"'.\\$id.'\\" style=\\"display: none;\\">'", $out);

    // replace ')' on its own on a new line (surrounded by whitespace is ok) with '</div>
    $out = preg_replace('/^\\s*\\)\\s*$/m', '</div>', $out);

    // print the javascript function toggleDisplay() and then the transformed output
    echo '<script language="Javascript">function toggleDisplay(id) { document.getElementById(id).style.display = (document.getElementById(id).style.display == "block") ? "none" : "block"; }</script>'."\
<pre>$out</pre>";
}

Krumo is exactly what Im looking for :stuck_out_tongue: ty

You’re welcome!

Krumo is pretty cool. I don’t use it in my CMS, but I’ve used it for other projects.

You should take a look at krumo, it does pretty much what you want.

It would be a fairly trivial exercise to parse the output/returned value from print_r to present it in whatever format you like (e.g differently for CLI and CGI).

7

Yeah, sounds like a job for jQuery, but it’d be nice if that could be built into tools such as xdebug. I cannot quite see how though.

Somebody almost certainly already made something like that :slight_smile:
But a php function that does that, I don’t think so. You’ll have to search for such a script, or write one yourself.
