Need link to open New browser window/tab…

Thanks for any help with this,

I need to open a new tab upon the user clicking on a link but still so wet under the ears in php code:

<?php if($testiurl) { ?>
									<a href="<?php echo $testiurl; ?>"><?php echo $testiurl; ?></a>
								<?php } ?>

I’ve tried:

<?php if($testiurl) { ?>
									<a href="<?php echo $testiurl; ?>"><?php echo $testiurl; ?> 'target="_blank"</a>
								<?php } ?>

and a few other ways, but still won’t work…

Thanks, Kevin
