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 %s<br/>\n", $i,

         ( 0 == $x ? '' : ( 1 == $x ? '' : '' ) )

    );

}

?>



Output:

0 

1 

2 

3 

4 

5 

6 

7 

8 

9 

10 

...



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:

(Sorry, but the Add Note function prevents me from including a long URL which points right to that section of the manual.)
