In $periods array first column is for single day (1 godinu), second is for more then one (2 godine) and third is the same but after 4 days in my country, we say different (5 godina). And it is different for everything, here is an example for all of them:

year = (1 = godinu), (2,3,4 = godine), (after 4 = godina)
month = (1 = mesec), (2,3,4 = meseca), (after 4 = meseci)
week = (1 = nedelju), (2,3,4 = nedelje), (after 4 = nedelja)
day = (1 = dan), (after 1 = dana)
hour = (1 = sat), (2,3,4 = sata), (after 4 = sati)
minute = (1 = minut), (after 1 = minuta)
second = (1 = sekund), (2,3,4 = sekunde), (after 4 = sekundi)

<?php
function time_elapsed_string($datetime, $full = false) {
    $now = new DateTime;
    $ago = new DateTime($datetime);
    $diff = $now->diff($ago);

    $diff->w = floor($diff->d / 7);
    $diff->d -= $diff->w * 7;

    $periods = array(
        'y' => ['godinu', 'godine', 'godina'],
        'm' => ['mesec', 'meseca', 'meseci'],
        'w' => ['nedelju', 'nedelje', 'nedelja'],
        'd' => ['dan', 'dana', 'dana'],
        'h' => ['sat', 'sata', 'sati'],
        'i' => ['minut', 'minuta', 'minuta'],
        's' => ['sekund', 'sekunde', 'sekundi']
    );

    $parts = array();
    foreach ($periods as $k => &$v) {
        if ($diff->$k) {
            $parts[] = $diff->$k . ' ' . $v[$diff->$k > 1];
        }
    }

    if (!$full) $parts = array_slice($parts, 0, 1);
    return $parts ? 'pre ' . implode(', ', $parts) : DATE_NOW;
}
?>

The correct units for each value can easily be chosen using a simple switch statement.

function time_elapsed_string($datetime, $full = false) {
    $now = new DateTime;
    $ago = new DateTime($datetime);
    $diff = $now->diff($ago);

    $diff->w = floor($diff->d / 7);
    $diff->d -= $diff->w * 7;

    $periods = array(

        'm' => ['mesec', 'meseca', 'meseci'],
        'w' => ['nedelju', 'nedelje', 'nedelja'],
        'd' => ['dan', 'dana', 'dana'],
        'h' => ['sat', 'sata', 'sati'],
        'i' => ['minut', 'minuta', 'minuta'],
        's' => ['sekund', 'sekunde', 'sekundi']
    );

    $parts = array();

        if ($diff->$k) {

                    $unit = $v[0];

                    $unit = $v[2];
            }
            $parts[] = $diff->$k . ' ' . $unit;
