while (using an array cursor) vs foreach

I am viewing a block of code which implements both of the following iteration methods at the same time. I'm wondering if there is a practical difference between the two methods of iteration? 

while (list($module) = each($module_list)) {
...
}

and

foreach ($module_list as $module) {
...
}

The latter is much more readable. There may be reasons to use the functions that implicitly change array cursors, but a simple iteration over all values is not such an occasion.
