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

function buildArrayFromPath( $path ) {
  $out = array();
  while( $pop = array_pop($path) ) $out = array($pop => $out);
  return $out;
}
