Can I edit a variable in a form

Hello,

Can I edit a variable in a form without using a database.

forexample

$title = "edit me";

PHP:

Can i call and edit $title in a form input?

Thanks

 

So you want to have a form to edit a PHP file directly if I understand you correctly?

Yes, you can do that, you'll have to do a regex to find the variable line in the PHP file, then replace it and save it.

So something like this: (it may not work, untested)

$contents = file_get_contents($filename);
$contents = preg_replace('/\$title = "[^"]";/i', '\$title = "' . $_POST['variable'] . '";', $contents);
file_put_contents($filename, $contents);

PHP:

 

I managed to write it.

<?php 
if (isset($_POST["Submit"])) { 

$string = '<?php  
$dbhost = "'. $_POST["dbhost"]. '"; 
$dbuname = "'. $_POST["dbuname"]. '"; 
$dbpass = "'. $_POST["dbpass"]. '"; 
$dbname = "'. $_POST["dbname"]. '"; 
$prefix = "'. $_POST["prefix"]. '"; 
$user_prefix = "'. $_POST["user_prefix"]. '"; 
$dbtype = "'. $_POST["dbtype"]. '"; 
?>'; 

$fp = fopen("config.php", "w"); 
fwrite($fp, $string); 
fclose($fp); 
} 
include "config.php"; 
?>

<form action="submit.php" method="post" name="install" id="install"> 
  <p><?=$dbhost?> <input name="dbhost" type="text" id="dbhost" value="<?=$dbhost?>"> DB Host</p> 
  <p><?=$dbuname?> <input name="dbuname" type="text" id="dbuname" value="<?=$dbuname?>"> DB Username</p> 
  <p><?=$dbpass?> <input name="dbpass" type="password" id="dbpass" value="<?=$dbpass?>"> DB Pass </p> 
  <p><?=$dbname?> <input name="dbname" type="text" id="dbname" value="<?=$dbname?>"> DB Name </p> 
  <p><?=$prefix?> <input name="prefix" type="text" id="prefix" value="<?=$prefix?>"> DB Prefix</p> 
  <p><?=$user_prefix?> <input name="user_prefix" type="text" id="user_prefix" value="<?=$user_prefix?>"> Userprefix</p> 
  <p><?=$dbtype?> <input name="dbtype" type="text" id="dbtype" value="<?=$dbtype?>"> DB Type </p> 
  <p><input type="submit" name="Submit" value="Install"></p> 
</form>
