Question

$name= path1
$key= key1
    public static function getpath($name, $key)
      {
        if (!self::is_valid($name, $key)) return false;
        $path = '/var/lib/fdata/'.$name.'/'.$key;
        if (!is_file($path)) return false;
        return $path;
      }

      public static function get($name, $key)
      {
        $path = self::getpath($name, $key);
        if ($path === false) return false;
        return file_get_contents($path);
      }

    $configmap = unserialize(fdata::get('base', 'key'));

The questions is:

1. if variable $path = self::getpath($name, $key); then $path = ? and what mean self::
2. if variable $configmap = unserialize(fdata::get('base', 'key')); then $configmap = ? and what mean fdata::

Answer 1

1) self::getpath(...) should return a boolean value or a string. self:: refers to a current class.

2) Here’s the man for unserialize

3)
fdata:: denotes the namespace fdata or perhaps a class.
