Why isn’t this get_posts() WordPress function not working?

I am trying to use the get_posts() function in WordPress to display a list of posts a specific category on my homepage. Here’s my code:

<div id="announcements">

    <?php 
    $myposts = get_posts( 'category'=>3 );
    foreach ( $myposts as $post ) : setup_postdata( $post );
    ?>

    <div id="announcement-post-title">
        <b><a href="<?php the_permalink() ?>" title="Permanent Link to 
                    <?php the_title(); ?>" class="homepage-post-title">
        <?php the_title(); ?></a></b>
    </div>


    <div id="announcement-post-content">
        <?php the_content(); ?>
    </div>

    <div id="announcement-post-read-more">
        <a href="<?php the_permalink() ?>" class="read-more-button">Read
                    More</a>
    </div>

    <?php endforeach; ?>

</div>

When I view the page, though, I get the following error:

Parse error: syntax error, unexpected T_DOUBLE_ARROW in /home1/mt/public_html/resources2/wp-content/themes/twentytwelve/front-page.php on line 26

Line 26 is this one:

$myposts = get_posts( 'category'=>3 );

Any ideas why this is happening?

Thanks in advance!
