wordpress - foreach only once -

i'm using metabox plugin wordpress, there 1 php command:

<?php $images = rwmb_meta( 'pw_project_photos', array('type'=>'plupload_image','size'=>'thumbnail') ); foreach ( $images $image ) { echo "<img src='{$image['url']}' alt='{$image['alt']}' />"; } ?>

what want to echo once, possbile?

for example, have upload 2 images 1 post, want show first image, not 2 images.

plz help me, thx lot!

you don't need loop through array if want echo 1 item.

simply do:

<?php if ( isset( $images[0] ) ) { $image = $images[0]; echo "<img src='{$image['url']}' alt='{$image['alt']}' />"; } ?>

wordpress foreach
