php - 格式化数组值

Question

我有一个像这样的数组

Array
(
    [0] => controllers
    [1] => event
    [2] => add_new_file.php

尝试:

$input  = array('controllers', 'event', 'add_new_file.php');
$output = null;

foreach (array_reverse($input) as $value) {
  if (is_null($output)) {
    $output = $value;
  } else {
    $output = array($value => $output);
  }
}

输出:

array (size=1)
  'controllers' => 
    array (size=1)
      'event' => string 'add_new_file.php' (length=16)
