Question

晚上好。首先对网络开发领域的新手表示歉意。我正在尝试创建一个可以输入文本的文本区域，刷新页面后会在文本区域上方显示该文本，以便我可以引用它。

我正在分阶段工作，到目前为止，我真的很难将用户输入从html转换为php，然后将其重新插入该页面。有人可以解释一下如何做到这一点吗？

我的代码包含在

下面

<!DOCTYPE HTML>
<html>
<head>
<meta charset="UTF-8">
<title>HTML php</title>
<link href="" rel="stylesheet" type="text/css" media="screen"> <!-- link to      CSS sheet -->
</head>
<body>
<h1>HTML php</h1>

<?php
//***************************************
// Gather Data from Form
//***************************************


 $HTMLNotes = $_POST['HTML_notes'];

 $DOCUMENT_ROOT = $_SERVER['DOCUMENT_ROOT'];

 $filename = $DOCUMENT_ROOT.'First Website/HTML/Html_Notes.txt';




 //***************************************
 //Add Name Information to File
 //***************************************

 $fp = fopen($filename, 'a');   //opens the file for appending

 $output_line = $HTMLNotes.'|'."\n";

 fwrite($fp, $output_line);

 fclose($fp);

 print "<h3>$HTMLNotes Added to File</h3>";

 ?>

<div class="container clearfix">

<?php

//--------------------------------------
//Reading info from file
//--------------------------------------

//Table of names --------------------------



    $display = "";
    $line_ctr = 0; //line counter

    $fp = fopen($filename, 'r'); //opens the file for reading

    while(true)
    {
        $line = fgets($fp); //gets one line at a time

        if (feof($fp)) //eof = end of file
        {
            break;
        }

        $line_ctr++;

        $line_ctr_remainder = $line_ctr % 2; //modulus of 2 and returns the   remainder so even will always return 0

        list($HTMLNotes) = explode('|', $line);

            print "<p>".$HTMLNotes."</p>";
            print "</tr>\n";  //added newline
               //added newline


    }

    fclose ($fp );

    print $display; //this prints the table rows





?>


 </div>

这是PhP，HTML在下面。对不起它一团糟
