A nested loop is a loop inside a loop. For instance, if you are reading posts on a forum sequentially, you would read:
Topic 1

Post 1
Post 2
Post 3

Topic 2

Post 1
Post 2
Post 3

So on the so forth.

If you want a purely programmatic example, run this code.

PHP Code:


			
<?php
for($i=0;$i<10;$i++)
{
    echo "Main Level $i - ";
    for($j=0;$j<10;$j++)
    {
        echo "Sub-Level $j - ";
    }
    echo "<br />";
}
?>

Here is what it will output:
