如何添加format_number到我的代碼

Question

我想顯示一個英文逗號分隔的數字。

此代碼從多個頁面獲取喜歡的數量，並將它們顯示在按喜歡的facebook數量排序的列表中。

function array_sort($array, $on, $order=SORT_ASC) 
{ 
$new_array = array(); 
$sortable_array = array(); 
if (count($array) > 0) { 
    foreach ($array as $k => $v) { 
     if (is_array($v)) { 
      foreach ($v as $k2 => $v2) { 
       if ($k2 == $on) { 
        $sortable_array[$k] = $v2; 
       } 
      } 
     } else { 
      $sortable_array[$k] = $v; 
     } 
    } 
switch ($order) { 
     case SORT_ASC: 
      asort($sortable_array); 
     break; 
     case SORT_DESC: 
      arsort($sortable_array); 
     break; 
    } 
    foreach ($sortable_array as $k => $v) { 
     $new_array[$k] = $array[$k]; 
    } 
} 
return $new_array; 
} 
function getLikes($arr){ 
$urls = ""; 
// Add urls to check for likes 
for($i = 0;$i < count($arr);$i++) { 
    if($urls != "") $urls .= ","; 
    $urls .= $arr[$i]; 
} 
// Retreive info from Facebook 
$xml = simplexml_load_file("http://api.facebook.com/restserver.php?method=links.getStats&urls=" . $urls); 
$likes = array(); 
// Loop through the result and populate an array with the likes 
for ($i = 0;$i < count($arr);$i++) { 
    $url = $xml->link_stat[$i]->url;      
    $counts = (int)$xml->link_stat[$i]->like_count;   
    $likes[] = array('likes' => $counts,'url' => $url); 
} 
return $likes; 
} 
$array = array("URL HERE","URL HERE"); 
$likes = getLikes($array); 
$likes = array_sort($likes, 'likes', SORT_DESC); 
$english_format_number = number_format($likes, 'likes'); 
foreach ($likes as $key => $val) { 
echo "<li class='facebook'><div class='fb-page'><div class='rank'>" . $key . "</div>" . "<div class='thumb " . $val['url'] . "'><div class='link'>" . $val['url'] . "</div></div>" . "<div class='likes'>" . $val['likes'] . "</div></div></li><br />"; 
} 

該代碼工作正常，順便說一下，我不是一個編碼器，只是剛剛進入它。

我是想的東西添加像

$english_format_number = number_format($likes, 'likes'); 

但是，當然，我不知道如果我能做到這一點或把它放在哪裏。

任何人都可以幫忙嗎？

Answer 1

您在number_format函數中使用了錯誤的參數。正確的格式是number_format（數字，小數點，小數點，分隔符）。所以改變你的代碼

$english_format_number = number_format($likes, 0, ',', '.') . 'likes';
