将数组转换为句子中的字符串[关闭]

I am just trying to convert some user id's to usernames in from an sql database. I know I shouldn't be using mySQl. I plan on switching over to PDO shortly...

  $getuseridsquery= "SELECT users.username FROM users WHERE users.id IN(". implode( ",", $uids) .")";
  echo $getuseridsquery;
  $getuseridsresult = mysql_query($getuseridsquery);
  $getuseridsresult1 = mysql_fetch_assoc($getuseridsresult);
  var_dump($getuseridsresult1);
  echo $getuseridsresult1;

  print '<p>Conversation between ';
  print implode(', ', $getuseridresult1) . ' and ' . $last;
  echo '.</p>';

I am getting:

 array (size=1)
  'username' => string 'ambe5950' (length=8)

when I var dump, so I just need to figure out how to convert that to the sentence below.

Sincere thanks for any help. It is greatly appreciated.

我只是想从sql数据库中将一些用户id转换为用户名。 我知道我不应该使用mySQl。 我计划很快切换到PDO ...

  $ getuseridsquery =“SELECT users.username FROM users WHERE users.id IN(”。implode(“,”,$  uids)。“)”; 
 echo $ getuseridsquery; 
 $ getuseridsresult = mysql_query($ getuseridsquery); 
 $ getuseridsresult1 = mysql_fetch_assoc($ getuseridsresult); 
 var_dump($ getuseridsresult1); 
 echo $ getuseridsresult1; \  n 
 print'&lt; p&gt;'; 
 print implode(',',$ getuseridresult1)之间的对话。  '和'。  $ last; 
 echo'。&lt; / p&gt;'; 
   
 
 

我得到:

   array(size = 1)
'username'=&gt; 字符串'ambe5950'(长度= 8)
   
 
 

当我进行var转储时,所以我只需要弄清楚如何将其转换为下面的句子。

真诚地感谢您的帮助。 非常感谢。

    The username part of that output is the index/key in your array. This is akin to what other languages call a Map or a Dictionary, but PHP allows for non-integer indexes in arrays. Simply put, you need to access the value via its index, which in this case is "username":

    $username = $getuseridsresult1['username'];
    echo $username; //prints "ambe5960"
    

    Also if you're not moving to PDO yet, then you should at the very least change mysql_* to mysqli_*.
