Dynamically creating forms through HTML/PHP

Yes, it is possible, of course.

It's not a good idea to store HTML in database. You can save dynamic data (e.g. input type, class, etc.) and then output them in page using simple php script when requested. For example:

echo '<input type="'.$type.'">'; //$type is data read from db.

As far as I knew form your comments, you don't know how many notes you have to write per user in db, so you'll need to get it as an array. For this you can name your inputs like: name[]. For example you can have this HTML inside your form:

<input name="fieldName[]" value="myField">
<input name="fieldName[]" value="anotherField">

When you get it using $_POST you'll get array:

[fieldName] => array(2)
               {
                    [0] => "myField",
                    [1] => "anotherField"
               }

So you if you do:

foreach ($_POST['fieldName'] as $field)
     echo $field;

output will be myFieldanotherField as you see it's executed one by another so you can store them in db using INSERT keyword. Here's how to save using PDO and here's more info about PDO

From PHP end create a whole website in dynamically there is no restriction best example is CMS below code i am just trying to help him how its logic create from PHP end

?>
    <div id="dynamic_field_<?php echo $i;?>"></div>
<?php 
}

<input  type="submit" value="submit" />
</form>

action .php

<pre>
<?php

$con = mysql_connect("localhost","root","");
if (!$con){
die('Could not connect: ' . mysql_error());
}

mysql_select_db("dynamic_form", $con);

mysql_query("
CREATE TABLE 
`dynamic_form`.`".$_REQUEST['table_name']."`
( `id` INT(11) NOT NULL AUTO_INCREMENT , `".$_REQUEST['txt_field']."` VARCHAR(225) , `".$_REQUEST['text_area']."` TEXT , PRIMARY KEY (`id`))  ;")
?>
