我通过网址获取数据,但它没有在user_id上显示任何记录。值ali40存在于数据库中,但未显示记录

http://celeritas-solutions.com/emrapp/surveyDescription.php?user_id=ali40

<?php 


   $linkID = mysql_connect($host, $user, $pass) or die("Could not connect to host."); 

mysql_select_db($ database,$ linkID)或死(“找不到数据库。”);

  if (!function_exists('json_encode'))


  {


  function json_encode($a=false)

 {

 if (is_null($a)) return 'null';
 if ($a === false) return 'false';
 if ($a === true) return 'true';
 if (is_scalar($a))
  {
   if (is_float($a))
   {
    // Always use "." for floats.
    return floatval(str_replace(",", ".", strval($a)));
    }



    if (is_string($a))
    {
      static $jsonReplaces = array(array("\\", "/", "\n", "\t", "\r", "\b", "\f", '"'), array('\\\\', '\\/', '\\n', '\\t', '\\r', '\\b', '\\f', '\"'));
     return '"' . str_replace($jsonReplaces[0], $jsonReplaces[1], $a) . '"';
    }
    else
    return $a;
}
$isList = true;
for ($i = 0, reset($a); $i < count($a); $i++, next($a))
{
  if (key($a) !== $i)
  {
    $isList = false;
    break;
  }
}
$result = array();
if ($isList)
{
  foreach ($a as $v) $result[] = json_encode($v);
  return '[' . join(',', $result) . ']';
 }
 else
 {
  foreach ($a as $k => $v) $result[] = json_encode($k).':'.json_encode($v);
  return '{' . join(',', $result) . '}';
 }
 }
}



  $user_id=$_GET['user_id'];






  echo($user_id);




   $query = mysql_query("SELECT s.*, u.user_id FROM survey_master AS s JOIN user_profile AS u on u.user_id = s.user_id where s.user_id='".$user_id."' ");




  $rows = array();
 while($row = mysql_fetch_assoc($query)) {
  $rows[] = $row;
  }
  echo json_encode($rows);

 ?>

程序PHP。

在使用mysql_fetch_assoc之前,使用:

执行sql
$result = mysql_query($query);

然后使用:

mysql_fetch_assoc($result)
