Access another page's title

Hi,

I am listing some sub pages in a custom 'category' parent page. So far I have managed to get the subdirectories into a string then use that in a foreach to get regions using perch_content_custom:

<?php $dirs = array_filter(glob('*'), 'is_dir');        
        foreach ($dirs as $course){
    ?>
    <section class="main-content">
        <h2><a href="/courses/<?php echo $course; ?>"><?php 
        // Title needs to go here
        echo $course; ?></a></h2>
    </section>
    <section class="courses" style="<?php perch_content_custom('Course Navigation Background Image', array('page' => '/courses/' . $course . '/index.php', 'template' => 'course-image.html') ); ?>">
        <?php 
        perch_pages_navigation(array(
            'from-path'=>'/courses/' . $course . '/index.php',
            'from-level'=>2,
            'template' => 'course-grid.html'     
        )); ?>
    </section>
    <?php    }
    ?>

But now I want to query the page to get it's title. How can I do this, if I cannot use perch_pages_title to get the information from another page?
