Notes on embedding code blocks

When writing programs, it is often common to embed conditions, or even other loops, within other loops or conditionals. For example, the following will count from 1 to 5 but display the string "Magic Number!" before it displays the number 3:
<?php $count = 1; while($count <= 5) { if($count == 3) { echo "Magic Number!<br />"; } echo $count."<br />"; $count++; } ?>
This feature is an important part of the language and is used quite frequently; it can be used in any syntax where a code block (distinguished by the { and } symbols) exists.
