是否有可能在php中保存在网页上所做的更改而无需发送到数据库中

Question

I have done some research on this topic but couldn't come up with a solution.

Is it possible in php to save changes made on web page without sending the infos into database??I'm giving each user the ability to make some changes on their pages and after changes made,every visitor of that page would be able to see the new edited text.

How can I do that?

Here is the sample php code

<?php

  if(isset($_POST['x']) && isset($_POST['hi'])){
   $hel=$_POST['hi'];
  }
 else{
   $hel="Hello There";
  }

?> 

HTML Part

<form id='sub' name='sub' method='post' action='edit.php' enctype='multipart/form-data'>
 <input type='text' id='hi' name='hi'>
 <input type='submit' id='x' name='x' value='publish'>
</form>
<?php echo $hel;?>

Thanks in advance.

Answer 1

No,It is not possible.That is what database for.Use database to store the changes,because that is the easiest and best way to do it.

Or you can store it as a file as well.This link might be useful,if you are not familiar with file handling .

Yet again,using database is better choice.

Answer 2

You have to save it somewhere in permanent storage. You get to choose - either a database or file. So if you don't want to store it in a DB, then store it in a file.

However when your data becomes complex and you want to link data to each other, you really need to go to a database.

Probably not what you're asking, but you can save data until you close the browser using sessions.

Start your script with:

<?php
session_start();

Then, save data inside $_SESSION :

$_SESSION['x'] = 'Whatever';
$_SESSION['hi'] = 'Great!';

Everything inside $_SESSION will stay even if you reload the page, until you close the browser.

If not, write bunch of JSON files to the filesystem.
