How to add default value for html <textarea>?

I am using ajax to send data from the form to the database and I have probem:

<input class="input" type="text" name="do_kogo" id="odbiorca" size="25" value="<?php print $odbiorca; ?>" />
<input class="input" id="temat" type="text" name="temat" size="25" value="<?php print $temat; ?>"/>
<textarea id="tresc_area" name="tresc" cols="45" rows="10" ></textarea>

As you can see I am changing the values to php equivalent and I don't know how can I change the value of the textarea to put there <?php print $tresc; ?>Please help me if somebody know how to do this. I would be so grateful.

You can add value in between <textarea> starting and ending tag.

<textarea id="tresc_area" name="tresc" cols="45" rows="10" ><?php print $tresc; ?></textarea>
