Question

我希望在页面的不同部分回显结果，而不仅仅是在标题中。我该怎么做呢？如果我想分别回收6个项目怎么办？

<?php 

    require_once 'facebook.php';
    $appapikey = 'CENSORED';
    $appsecret = 'CENSORED';
    $facebook  = new Facebook($appapikey, $appsecret);
    $user_id  = $facebook->require_login();
    $user   = $user_id;
    $i = 0;
     $fql = 'SELECT uid FROM user WHERE uid IN (SELECT uid2 FROM friend WHERE uid1='.$user.')';
     $_friends = $facebook->api_client->fql_query($fql); // Extract the user ID's returned in the FQL request into a new array. 
     $friends = array(); 
     if (is_array($_friends) && count($_friends)) 
     {
      foreach ($_friends as $friend) 
      { 
       $i++;
       $friends[] = $friend['uid'];
       if ($i<=6) echo $friend['uid']."@[,:m]";
      } 
     }
    ?>


    <br><br>HELLO

Answer 1

不要echo。收集字符串变量中的所有输出，并在真正需要时收集echo。

Answer 2

如果它位于同一页面上，您只需在页面上的任何位置访问$ _friends变量即可。

require_once 'facebook.php';
$appapikey = <KEY>;
$appsecret = <SECRET>;
$facebook  = new Facebook($appapikey, $appsecret);
$user_id  = $facebook->require_login();
$user   = $user_id;
$i = 0;
 $fql = 'SELECT uid FROM user WHERE uid IN (SELECT uid2 FROM friend WHERE uid1='.$user.')';
 $_friends = $facebook->api_client->fql_query($fql); // Extract the user ID's returned in the FQL request into a new array. 
 $friends = array(); 
 if (is_array($_friends) && count($_friends)) 
 {
  foreach ($_friends as $friend) 
  { 
   $i++;
   if ($i<=6) $friends[] = $friend['uid']."@[,:m]";
  } 
 }
?>

 BUNCH OF STUFF

<?php
// You need to display some friend data
foreach($friends as $friend) {
  echo $friend;
}

然后用$ friends变量做任何你想做的事。

将包含echo语句的循环移动到页面的另一部分，或将结果存储在数组中，稍后再echo。

我无法在文件的单独部分中获得结果
