我将包含特殊字符的变量(例如@#$(用于描述一些))存储到会话和使用PHP的cookie中,但是当我检索它们时,我无法在存储的会话和cookie变量中看到特殊字符。提前谢谢。
//storing
$_SESSION['userid'] = $db_id;
$_SESSION['email'] = $db_email;
$_SESSION['password'] = $db_pass_str;
setcookie("id", $db_id, strtotime( '+30 days' ), "/", "", "", TRUE);
setcookie("email", $db_email, strtotime( '+30 days' ), "/", "", "", TRUE);
setcookie("pass", $db_pass_str, strtotime( '+30 days' ), "/", "", "", TRUE);
//Retreivel
if(isset($_SESSION["userid"]) && isset($_SESSION["email"]) && isset($_SESSION["password"]))
{
$log_id = preg_replace('#[^0-9]#', '', $_SESSION['userid']);
$log_email = preg_replace('#[^a-z0-9]#i', '', $_SESSION['email']);
$log_password = preg_replace('#[^a-z0-9]#i', '', $_SESSION['password']);
// Verify the user`enter code here`
}
else if(isset($_COOKIE["id"]) && isset($_COOKIE["email"]) && isset($_COOKIE["pass"]))
{
$_SESSION['userid'] = $_COOKIE['id'];
$_SESSION['email'] = $_COOKIE['email'];
$_SESSION['password'] = $_COOKIE['pass'];
}
当我回显会话变量时,我没有看到我存储的特殊字符。 例如:我存储了test@example.com,但是当我查看时,我只能看到testexample.com。

使用htmlspecialchars对原始字符串进行编码。 例如,
<?php
$session_variable = "hello@World#$%@";
$new = htmlspecialchars("<?php echo $session_variable; ?>", ENT_QUOTES);
echo $new; // output: hello@World#$%@
?>
