If you are looking for a getlocale() function simply pass 0 (zero) as the second parameter to setlocale().

Beware though if you use the category LC_ALL and some of the locales differ as a string containing all the locales is returned:

<?php
echo setlocale(LC_ALL, 0);

// LC_CTYPE=en_US.UTF-8;LC_NUMERIC=C;LC_TIME=C;LC_COLLATE=C;LC_MONETARY=C;LC_MESSAGES=C;LC_PAPER=C;LC_NAME=C;
// LC_ADDRESS=C;LC_TELEPHONE=C;LC_MEASUREMENT=C;LC_IDENTIFICATION=C

echo setlocale(LC_CTYPE, 0);

// en_US.UTF-8

setlocale(LC_ALL, "en_US.UTF-8");
echo setlocale(LC_ALL, 0);

// en_US.UTF-8

?>

If you are looking to store and reset the locales you could do something like this:

<?php

$originalLocales = explode(";", setlocale(LC_ALL, 0));
setlocale(LC_ALL, "nb_NO.utf8");

// Do something

foreach ($originalLocales as $localeSetting) {
  if (strpos($localeSetting, "=") !== false) {
    list ($category, $locale) = explode("=", $localeSetting);
  }
  else {
    $category = LC_ALL;
    $locale   = $localeSetting;
  }
  setlocale($category, $locale); 
}

?>

The above works here (Ubuntu Linux) but as the setlocale() function is just wrapping the equivalent system calls, your mileage may vary on the result.
