for ($i = 0; $i < (count($allkey)); $i++)
{
    if (str_word_count($allkey[$i]) < 2)
    {
        unset($allkey[$i]);
    }
    else
    {
        echo $allkey[$i]."<br />";
    }
}

There is the code

$all = "smart lion, smart duck, small ant, , pig, pelican";
$allkey = explode (',',$all);
$allkey = array_unique($allkey);
for ($i = 0; $i < (count($allkey)); $i++)
{
    //we count the number of words
    $allwords = explode (' ',$allkey[$i]);
    //Remove empty words
    for ($j = 0; $j < (count($allwords)); $j++) {
        if ($allwords[$j]=="") unset($allwords[$j]);
    }
    if (count($allwords)<2)
        unset($allkey[$i]);
    else
        echo trim($allkey[$i])."\n";
}
