Fixes for PHP 8

[abiusx]

How does this fix for PHP 8? Seems like you just reordered args into the functions.

[q-u-o-s-a]

/**
 * Returns descendants of a node, with their depths in integer
 *
 * @param integer $ID
 * @return array with keys as titles and Title,ID, Depth and Description
 *
 */
function descendants($ID)
{
	$res = $this->{$this->type()}->descendantsConditional("ID=?", false, $ID);
	$out = array();
	if (is_array($res))
		foreach ($res as $v)
			$out[$v['Title']] = $v;
	return $out;
}

should be like this!!

Was this the only change that was needed to make this PHP 8 compatible?

[q-u-o-s-a]

should be $res = $this->{$this->type()}->descendantsConditional("ID=?", false, $ID);

[q-u-o-s-a]

I am using the package in Php 8 (8.0.28 and 8.0.30) and the source is working fine.

In Php 8 optional arguments ($AbsoluteDepths=false,$ConditionString) should be after necessary arguments.
Exenation: https://php.watch/versions/8.0/deprecate-required-param-after-optional

Thats the reason why most of your forks (i checked about 20) are doing it this way.

I really recommand to accept th PR after changing:

$res = $this->{$this->type()}->descendantsConditional("ID=?", false, $ID);
