我有一个fwrite编写每个业务的页面，但我想要它，以便它只显示页面的HTML，当你去有效会话的网址，所以我写了 FWRITE（$ FP”
然而，当它写入页面时，它会写入此内容。 isset语句已从if语句中删除。
<?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'>

$linksTable = "<table id='links'>

</table>";
$bodyClose = "</body>";
$htmlClose = "</html>";
$isset = "{$_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);
}
这是它写的页面

答案 0 :(得分：2)
原因是您使用以下行：
fwrite($fp, "if(isset({$_SESSION['id']})) { ?");
因为您使用双引号，这意味着在通过fwrite写入文件之前，PHP将解析会话值{$_SESSION['id']}。如果您将引号更改为单引号，则不会出现此问题，因为PHP将仅保留单引号字符串 - 即不为变量解析它们：
fwrite($fp, 'if(isset($_SESSION["id"])) { ?');
你还应该删除会话var上的周围花括号，除非你希望你的php在重新解析时是错误的。
这是假设您在文件中想要的结果是：
if(isset($_SESSION["id"])) { ?
