我有一个写每个业务页面的 fwrite，但我想要它，以便它只在您使用有效会话访问 url 时显示页面的 html，所以我写了 fwrite($fp,"

但是，当它写入页面时，它会写入 this 。isset 语句从 if 语句中消失了。

    <?php

$recid = $_POST['recid'];
$username = $_POST['name'];
$email = $_POST['email'];
$ownername = $_POST['ownername'];

include ("connection.php");


$result = $db->query("UPDATE users SET verified='y' WHERE recid='$recid'"); 

$doctype      = "<!DOCTYPE html>";
$htmlOpen     = "<html>";
$head         = "<head> <meta http-equiv='Content-Type' content='text/html; charset=ISO-8859-1'>

                </table>

$bodyClose    = "</body>";

$isset = "{$_SESSION['id']}";

$filename = str_replace(" ","_", trim($username) ); 
mkdir("Business_Pages/" . $filename."/");

if( $fp = fopen("Business_Pages/" . $filename . "/" . $filename . ".php", "w") )
{
  fwrite($fp,"<?php session_start();");
  fwrite($fp, "if(isset({$_SESSION['id']})) { ?");
  fwrite($fp, $doctype.$htmlOpen.$head.$bodyOpen.$header.$wcImage.$accountTable.$linksTable.$bodyClose.$htmlClose);
  fwrite($fp,"<?php } else { echo \"User not logged in\";} ?>");
  fclose($fp);
}

这是它写入的页面

原因是因为您使用的是以下行：

fwrite($fp, "if(isset({$_SESSION['id']})) { ?");

因为您使用双引号，这意味着会话值{$_SESSION['id']}将由 PHP 解析，然后通过 fwrite 写入文件。如果将引号更改为单引号，则不会出现此问题，因为 PHP 将单独保留单引号字符串 - 即不解析它们的变量：

fwrite($fp, 'if(isset($_SESSION["id"])) { ?');

您还应该删除会话变量上的大括号，除非您希望您的 php 在重新解析时出错。

这一切都假设您在文件中想要的结果是：

if(isset($_SESSION["id"])) { ?
