php - session 可以在本地主机上运行，​​但不能在服务器上运行(Ipage 等..)

Question

这是一个代码:

 <?php
    require_once('./includes/connection.inc.php');
    session_start();

    // create database connection
    $connread = dbConnect('read', 'pdo');

    $connwrite = dbConnect('write', 'pdo');
    $komentari = 'SELECT * FROM komentariodobreni ORDER by komentarodobren_id DESC';

    $kontakt = 'SELECT poruka_id, ime, prezime, email, predmet, ordinacija, poruka,      DATE_FORMAT(datum, "%H:%i:%s %d. %b. %Y") 
     AS datum  FROM kontakt ORDER by poruka_id DESC';


    if (isset($_POST['slanje'])) {
    $potvrdiquery = "SELECT * FROM kontrola WHERE adminname='" . $_POST["adminname"] . "' and adminpassword = '". $_POST["adminpassword"]."'";
     $stmt = $connwrite->prepare($potvrdiquery )

    ;
      // bind the parameters and execute the statement  
      // execute and get number of affected rows
      $stmt->execute();
      $OK = $stmt->rowCount();


    foreach ($connread->query($potvrdiquery) as $row) {
    $_SESSION['adminid'] = $row['adminid'];
    $_SESSION["adminname"] = $row["adminname"];
    $_SESSION["adminpassword"] = $row["adminpassword"];
    } 
     header('Location: index.php');
    } 
?>

它在我的本地运行良好，但是当我将其上传到 Ipage 或其他服务器时，它不会注册 session 变量。

尝试像这样重新排列session_start():

<?php
  session_start();
  require_once('./includes/connection.inc.php');
  ...

并尝试一下。 connectoin.inc.php 中可能出现问题(错误或输出)，导致 session_start() 无法正常工作。

为了帮助调试问题，添加如下错误输出:

<?php
  session_start();
  error_reporting(E_ALL);
  ini_set('display_errors', '1');
  require_once('./includes/connection.inc.php');
  ...
