Just as an addendum to all the answers, it is the "ID" field that you cannot have two of the same, that will cause problems in an HTML form.tremor– tremor2014-03-21 12:38:15 +00:00Commented Mar 21, 2014 at 12:38

Do you really mean "in PHP" or "in HTML".... it's possible to create any output in PHP, whether valid or notMark Baker– Mark Baker2014-03-21 12:41:23 +00:00Commented Mar 21, 2014 at 12:41

Yes. Element ids must be unique, but names do not.
Is there any problem while the form is submitted?
PHP will discard all but the last one unless the name ends in [].
<input name="foo[]">
<input name="foo[]">
will be accessible via
$_POST['foo'] # an array

there is always the possibility to use array like syntax e.g.
<input type="text" name="my-field[]">
<input type="text" name="my-field[]">
in php you can access it using something like
$_REQUEST['my-field'][0]
Comments
You may add the array bracket [] onto each input box. like this;
<form method="post" action="somepage.php">
<input type="text" name="box[]">
<input type="text" name="box[]">
<input type="submit" name="submit" value="Submit">
</form>
Then on somepage.php
<?php
if(isset($_POST['submit']))
{
echo $_POST['box'][0];
echo $_POST['box'][1];
}
?>
The [] makes two boxes to be submitted as an array
Comments
Yes you can create with array parameter.
<form>
<input type="text" name="txtname[]">
<input type="text" name="txtname[]">
</form>
You will get value using $_REQUEST['txtname'] which is array.

Hello! I noticed that you end your all answers with a “Thanks”, unfortunatly this is discouraged here on SO to leave place for the actual contents of your answer. Have a look at this Meta Post: meta.stackexchange.com/q/2950/174540 Also: Check your formatting before you submit your answer. You accidentally put your text inside the code block as well.
