我不太清楚你的代码是做什么的，因为我看不到任何关于设置用户名或诸如此类的内容。代码的作用是启动会话并检查会话中的username变量是否已设置，如果已设置，则调用session\u id

你能用它来检查会话创建是否正确吗
session_start();
if (session_status() !== PHP_SESSION_NONE)
{
echo session_id();
}

如果会话状态不是PHP\u session\u NONE
，则启动会话并显示会话ID。您的会话可能未设置。根据您使用的PHP版本，检查会话
对于PHP的版本=5.4.0
if (session_status() == PHP_SESSION_NONE) {
    session_start();
}

对于PHP的版本<5.4.0
if(session_id() == '') {
    session_start();
}

启动会话不需要执行session\u id（），session\u start（）就足够了
我在iPhone 6上的Safari上测试了以下内容（如果需要，只需重新添加db查询部分）：
testa.php
<?php
//require('config.php');

session_start();
echo "Session ID: ".session_id()." <br>\n";

    $username = $_POST['username'];
    $password = $_POST['password'];

    $usernameOK = true;
    $passwordOK = true;

    if ($usernameOK == true && $passwordOK == true) {
        $_SESSION['username'] = $username;
    } else {
        $error_message = "Incorrect login data";
    }
}

if (isset($_SESSION['username'])) {
    header("Location: ../");
    exit;
} else {

        <button type="submit">Login</button>
        <a class="form-link" href="register.php">Register</a>
    </form>
<?php } ?>

    else
    {
        session_start();
        $_SESSION['username'] = $username;
    }
     print_r($_SESSION);

    session_start();

编辑：我注意到您正在使用函数重定向到索引页。除非您将用户发送出系统，否则避免此类重定向非常重要，因为某些环境不能很好地使用它们。我建议将例程改为用户POST/GET http例程：
内部validateSession.php
在validateSession之外，与会话规则无关，将所有内容集中在那里
index.php/head.php/一些总是在每个页面中开始的代码只会开始：
<?php 
include_once('validateSessions.php'); 
?>



您的表格：
<form class="login-form" action="index.php" method="POST"> 
<?php if(isset($error_message)){ ?><div class="mini-mes error"> <?php echo $error_message; ?> </div><?php } ?> 

<span class="placeholder">username</span> 
<input type="text" name="username" placeholder="username" required> 

<span class="placeholder">password</span> 
<input type="password" name="password" id="inputPassword" placeholder="password" required> 

<button type="submit">Login</button> 
<a class="form-link" href="register.php">Register</a>

编辑：我回顾了你的例程，注意validateSessions.php，我忘记在调用该文件的每个例程中加载session_start（）。将validateSessions放在include目录中
更新：即使我的代码帮助了OP，主要的问题还是将会话配置到带有SESSION.save_路径的php.ini文件中，导致会话例程出现问题。php.ini修复程序解决了这个问题，我认为这段代码有助于OP思考一些有关会话内容的例程。
简化了代码，使其更易于理解。忽略用户名和密码等检查。您基本上是在尝试设置会话变量。这在login.php中发生。代码是
 <?php
 $username = "Umesh";
 if (isset($_SESSION))
 {
      $_SESSION['username'] = $username;
 }
 else
 {
           session_start();
           $_SESSION['username'] = $username;
 }
 print_r($_SESSION);
?>

以上内容适用于我的所有浏览器和设备。我甚至在iphone上测试了chrome。它似乎工作得很好。请检查一下，看它是否有效。如果没有，我们将不得不检查您的Web服务器，看看该系统上的会话对象有什么问题
我验证了print\u r（$\u SESSION）在这两种情况下是相同的。
根据您的上一条评论，我猜这是由于您使用的查询字符串。基本上，使用password
作为列名有时会中断查询，因为password也是一个mysql关键字。
此外，关于您的会话，您可以参考以了解有关功能的更多详细信息Session\u id（“login”）
基本上将会话id设置为login，该id在您的移动设备上工作，因为这将创建具有特定静态id的会话。但是，您可以尝试使用Session\u regenerate\u id（true）
查看是否有帮助
我还尝试通过将静态值作为用户名来执行代码，如下所示
login.php
<?php
//require('config.php');

session_start();
echo "Session ID: ".session_id()." <br>\n";

$usernameOK = false;
$passwordOK = false;

if (isset($_POST['username']) and isset($_POST['password'])) {

    $username = $_POST['username'];
    $password = $_POST['password'];

    $usernameOK = true;
    $passwordOK = true;

    if ($usernameOK == true && $passwordOK == true) {
        $_SESSION['username'] = $username;
    } else {
        $error_message = "Incorrect login data";
    }
}

if (isset($_SESSION['username'])) {
    header("Location: ../");
    exit;
} else {
?>
    <form class="login-form" method="POST">
        <?php if (isset($error_message)) { ?>
            <div class="mini-mes error"> <?php echo $error_message; ?> </div><?php } ?>

        <span class="placeholder">username</span>
        <input type="text" name="username" placeholder="username" required>

        <span class="placeholder">password</span>
        <input type="password" name="password" id="inputPassword" placeholder="password" required>

        <button type="submit">Login</button>
        <a class="form-link" href="register.php">Register</a>
    </form>
<?php } ?>

<?php

session_start();
echo "Session ID: ".session_id()." <br>\n";
echo "Data stored in session: {$_SESSION['username']}<br>\n";

 <?php
    $username = "deadlock";
    if (isset($_SESSION))
    {
        $_SESSION['username'] = $username;
    }
    else
    {
        session_start();
        $_SESSION['username'] = $username;
    }
     print_r($_SESSION);

<?php
if (isset($_SESSION['username'])){
    session_regenerate_id(true);
} else if (!isset($_SESSION)){
    session_start();
}
print_r(session_id());

为什么要使用session\u id（）。会话我总是使用这个登录系统。我的桌面或移动会话没有问题

我的问题出现在服务器端的会话上。保存路径未定义到我的服务器。非常感谢所有帮助我的人：）
检查会话\u start（）是否放在任何浏览器输出之前。我发现桌面上的Chrome浏览器比其他浏览器以及移动Chrome浏览器要宽容得多
