Seleting the first word in a result

[elfeste]

Does anyone know how to trim a result to the first word only.

 

For example

 

John Brown  to John

Cat in a hat  to Cat

<?php

<?php
$data = "John Brown";
$data = "Cat in a hat";

if (preg_match('/(\w+)/i', $data, $regs))
{
$firstword= $regs[1];
}

echo $firstword;
?>
?>
