It's useful to know how the .po-file has to look like when using ngettext:
msgid "item"
msgid_plural "items"
msgstr[0] "Produkt"
msgstr[1] "Produkte"
In php:
echo ngettext('item', 'items', $number);
ngettext
(PHP 4 >= 4.2.0, PHP 5)

According to GNU gettext manual third argument is unsigned long integer. It must be positive number. If n is negative, it might be evaluated incorrectly in some languages.

This is an implementation for a word ending in russian lang. Also as I know polish and similar langs use same rules:
<?php
/**
* Returns:
* 0, if $n == 1, 21, 31, 41, ...
* 1, if $n == 2..4, 22..24, 32..34, ...
* 2, if $n == 5..20, 25..30, 35..40, ...
*/
function plural( $n )
{
if ( $n % 10 == 1 && $n % 100 != 11 )
{
return 0;
}
if ( $n % 10 >= 2 && $n % 10 <= 4 && ( $n % 100 < 10 || $n % 100 >= 20 ) )
{
return 1;
}
return 2;
}
// usage
for ( $i = 0; $i < 100; $i++ )
{
$x = plural( $i );
printf(
"%d тетрад%s<br/>\n", $i,
( 0 == $x ? 'ь' : ( 1 == $x ? 'и' : 'ей' ) )
);
}
?>
Output:
0 тетрадей
1 тетрадь
2 тетради
3 тетради
4 тетради
5 тетрадей
6 тетрадей
7 тетрадей
8 тетрадей
9 тетрадей
10 тетрадей
...
Also here is short version:
<?php
$n = 17;
print ($n%10==1 && $n%100!=11 ? 0 : ($n%10>=2 && $n%10<=4 && ($n%100<10 || $n%100>=20) ? 1 : 2));
?>
output: 2

Section 10.2.5 in the GNU gettext manual explains the ngettext function:
http://www.gnu.org/software/gettext/manual/
(Sorry, but the Add Note function prevents me from including a long URL which points right to that section of the manual.)
