Thanks for your reply.
But the disabled attribute does not show the value. I want that the value should not be disappered after user clicks submit button and also the value should be unchangable.

Thanks for your reply. The entered value disappears when I click the button, even if I make it readonly. I need to make the text box value read only after first click.

Thanks for your help. Can you please explain me this line:
$value = isset($_POST['name']) ? $_POST['name']:"10";if I place $_POST instead of 10 then will it be correct?
or it can be possible as:
<input type="text" name="ch1" value = "<?echo $_POST['ch1']; ?>" />I don't see element guess_value in this code! :) Well, here is an example.
<?php $value = isset($_POST['name']) ? $_POST['name']:"10"; ?> <html> <body> <form method='post'> <input type='text' name='name' value='<?php echo $value; ?>' readOnly='readOnly'> <input type='submit' name='submit' value='submit'> </form> </body> </html>I have hard-coded value 10.

$value = isset($_POST['name']) ? $_POST['name']:"10"; ? is called Ternary Operator. In the example above, I am checking if $_POST is set and has a value. If has a value, I am assigning it to the variable $value. If it doesn't have any value, I am assigning 10 to $value.
You can read more about ternary operator here.
http://in.php.net/operators.comparison
<input type="text" name="ch1" value = "<?echo $_POST; ?>" />
This will retain whatever value the user had entered in the textbox "ch1".
Edit: I don't recommend using <? (or short tags). Short tags are turned off on most servers, which would result in printing the php code to the screen. Use <?php instead.

Its not showing the values in the textbox because you are using header function to redirect the user back to guess.php . Learn more about $_GET and $_POST here.
