First form for posting the number of the textareas:

<form action="posting.php" method="post">
    <input type="text" name="textareasNum">
    <input type="submit" value="Send the number of textareas">
</form>

The posting.php is:

<form action="3.php" method="post">
    <?php
        $num = $_POST['textareasNum'];
        for($i = 0; $i < $num; $i++)
           {
    ?>
             <textarea name="o<?php echo $i;?>">
             </textarea>
    <?php
           }
    ?>
</form>

First of all, thank you so much for this, It works fine! :) Last question:) How can I code to gather entered values in textareas ? I couldn't create a valiable name like o2 or o8 dynamically

Sure you can, like this: for($i = 0; $i < $num; $i++){ $data_array[] = $_POST['o'.$i];}. Now, you have all the values you want in $data_array[].

Previous code is for 3.php file. You can send the $num value using this: <input type="hidden" value="<?php echo $num;?>" /> after <form> tag.
