您可以像这样在隐藏字段中传递上一条消息
<?php
if(isset($_POST['submit']) && isset($_POST['prevmsg'])){
echo "New Message :".$_POST['message'];
echo "Previous Message :".$_POST['prevmsg'];
}
if(isset($_POST['submit']) && $_POST['submit']=='Submit'){
$message=$_POST['message'];
$name=$_POST["name"];
echo $name . "<br />" . $message;?>
<html>
<head>
</head>
<body>
<form method="POST" action="<?=$_SERVER["PHP_SELF"]?>">
<br>Name:<input type="text" name="name" id="name">
<br>Message:<textarea name="message" id="message"></textarea>
<input type="hidden" name="prevmsg" value="<?=$message?>"/>
<br><input type="submit" name="submit" value="Submit"/>
</form>

让你继续前进的肮脏解决方案
<?php
if(isset($_POST['submit']) && $_POST['submit']=='Submit'){
$message=$_POST['message'];
$name=$_POST["name"];
if( isset( $_COOKIE['previous_message'] ) ) {
$the_previous = explode(';', $_COOKIE['previous_message']);
echo $the_previous[0] . "<br />" . $the_previous[1];?>
} else {
setcookie('previous_message', $name . ';' . $message);
}
setcookie('previous_message', $name . ';' . $message);
echo $name . "<br />" . $message;?>
}否则{
setcookie（'previous_message'，$name.；'。$message）；
}
setcookie（'previous_message'，$name.；'。$message）；
echo$name。“
