Question

Zur Zeit habe ich einige Code, der Namen und listet sie wie User1, User2 and User3 likes this

$MoreLikers = $this->DBHandle->mysqli->query("SELECT * FROM thread_reply_likes WHERE post_receiver = '".$Row["id"]."'"); 
while($FetchLikers = $MoreLikers->fetch_array()) { 
    $like_user = $this->DBHandle->mysqli->query("SELECT * FROM users WHERE id = '".$FetchLikers["user_giver"]."'"); 
    $LuArray = array(); 
    while($RowLu = $like_user->fetch_array()) { 
     $LuArray[] = $RowLu; 
    } 

    $LuArrayz[] = ""; 

    foreach($LuArray as $Rowz) { 
     $TheLikersList[] = $Rowz["username"]; 

    } 

    if($MoreLikers->num_rows < 4) { 
     $last = array_slice($TheLikersList, -1); 
     $first = join(', ', array_slice($TheLikersList, 0, -1)); 
     $both = array_filter(array_merge(array($first), $last), 'strlen'); 
     $TheLikers = join(' and ', $both); 

     $ListLikers = "<i class='fa fa-thumbs-up'></i> " . $TheLikers . " likes this"; 
    } else { 
     // what to put here if num_rows are more than 3? 
    } 
} 

Was ich tun möchte, abzurufen ist, wenn die Anzahl von Benutzern (num_rows grundsätzlich) sind mehr als 3, um es wie User1, User2, User3 and X others likes this zu zeigen, wobei X die num_rows minus 3 ist.

Ich bin mir nicht sicher, wie das geht. Jede Hilfe wird geschätzt!

Insert $MoreLikers->num_rows in der Mitte:

if($MoreLikers->num_rows < 4) { 
     $last = array_slice($TheLikersList, -1); 
     $first = join(', ', array_slice($TheLikersList, 0, -1)); 
     $both = array_filter(array_merge(array($first), $last), 'strlen'); 
     $TheLikers = join(' and ', $both); 
     $ListLikers = "<i class='fa fa-thumbs-up'></i> " . $TheLikers . 
         " likes this"; 
} else { 
    $three = array_slice($TheLikersList,0,3); 
    $TheLikers = join(', ', $three); 
    $ListLikers = "<i class='fa fa-thumbs-up'></i> " . $TheLikers . 
        " and " . ($MoreLikers->num_rows-3) . " others like this"; //<======= 
    }
