strpos question

[jeff5656]

If $_GET['pt'] is something like  smith, john, I do this

<input type="text" size="12"  name="lname" value="<?php echo substr($_GET['pt'],0,strpos($_GET['pt'],','));?>"/>

to only include the last name in this value.

 

But if there are no commas, that field is blank.  How do I re-write this such that IF there are NO commas, then make the value ALLof $_GET['pt']?

$h1 = explode(',','john,smith');

//$h1[0] = john

//$h1[1] = smith
