我想通过使用与该文本位于同一文件中的表单来填充文本，该文本位于 pintStory（） 函数中，我想要表单和程序是一个文件。
<! DOCTYPE html>
<html>
<head>
<title>Story</title>
<link rel="stylesheet" type="text/css href="story.css"/>
</head>
<body>
<?php
storyForm();
printStory();
function storyForm(){
print <<<HERE
<h1>Story</h1>
<h3>Please fill in the blanks below,and then I'll tell you a story</h3>
<form method="post" action="">
<fieldset>
<label>Color:</label>
<input type="text" name="instrument"/>
<label>animal</label>
<input type="text" name="anim1"/>
<label>another animal</label>
<input type = "text" name = "anim2" />
<label>one more animal:</label>

<label>vegetable: </label>

$color=filter_input(INPUT_POST, "color");

function printStory(){

print<<<HERE
<h1>Little Boy who?</h1>
HERE;
print<<<HERE
<h2>
Little Boy $color,come blow your $instrument!<br/>
The $anim1's in the $place, the $anim2's in the $vegetable.<br/>
Where's the boy that looks after the $anim3?<br/>

试试这个它会起作用：
<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
$_SERVER['PHP_SELF']可帮助您在同一页面上重定向。 并请更正表单方法的拼写。将pst替换为 post 。
