Display “get_pages” Array in Random Order?

Hello everyone.

I’ve written the code below to pull three testimonials from the portfolio section of a site and display them on the home page. Everything is working fine, except I can’t seem to get them to display in a random order.

Is there a way to do this using “get_pages”, or am I stuck always showing them in a specific order?

Here’s the code:

<?php

	$pages = get_pages(array('child_of' => 15, 'meta_key' => 'testimonial', 'number' => 3));

	foreach($pages as $child) {

		$testimonial = get_post_meta($child->ID, 'testimonial', false);
		$projName = get_the_title($child->ID);
		$projLink = get_permalink($child->ID);

	if ($testimonial) {

		foreach ($testimonial as $testimony) {

			$fullValue = explode("|", $testimony);

			$docPic = $fullValue[0];
			$docQuote = $fullValue[1];
			$docName = $fullValue[2];

			?>

			<li class="testimonial">

				<img src="<?php echo $docPic; ?>" alt="<?php echo $docName; ?>" title="<?php echo $docName; ?>" />

				<p class="quote">&ldquo;<?php echo $docQuote; ?>&rdquo;</p>

				<p class="cite"><span class="doc"><?php echo $docName; ?></span> | <a href="<?php echo $projLink; ?>" title="<?php echo $projName; ?>"><?php echo $projName; ?></a></p>

			</li><!-- /.testimonial -->

			<?php

		}

	}

	}

?>

Thanks for whatever help you can provide! 🙂
