General help

Hi, this is a snippet from something I was developing, you may have to fiddle a bit but it should work...

<?php
$mycourses = get_my_courses($USER->id);
$catArr = array();

foreach ($mycourses as $mycourse){
array_push($catArr,$mycourse->category);
}

$catArr = array_unique($catArr);

sort($catArr);

foreach ($catArr as $cat){
$myCat = get_records_select('course_categories',"id='$cat'",'name ASC','id, name');
foreach ($myCat as $mCat){
echo '<h4>'.$mCat->name.'</h4>';
}
echo '<ul>';
foreach ($mycourses as $mycourse){
if ($mycourse->category == $cat){
echo '<li><a href="../course/view.php?id='.$mycourse->id.'">'.$mycourse->fullname.'</a></li>';
}
}
echo '</ul>';
}
?>
