Set multi-dimensional array by key path from array values?

Question

Sorry for the terrible title, best I could think of at the time! Say I have a \'path\' array like so;

array(\'this\', \'is\', \'the\', \'path\')

Answer 1

Just iterate over it with something like array_shift or array_pop:

$inarray = array('this', 'is', 'the', 'path',);
$tree = array();
while (count($inarray)) {
    $tree = array(array_pop($inarray) => $tree,);
}

Not tested, but that's the basic structure of it. Recursion also fits the task well. Alternatively, if you don't want to modify the initial array:

$inarray = array('this', 'is', 'the', 'path',);
$result = array();
foreach (array_reverse($inarray) as $key)
    $result = array($key => $result,);
