It's good to know that if you accidentally (or purposefully) put a semicolon at the end of the
first line of a foreach statement, no error or warning will be thrown. Instead, the foreach will
iterate only on the last entry in the array. Therefore,
<?php
$array = array('a', 'b', 'c', 'd');
foreach ( $array as $letter ); // <--Semicolon at end of foreach statement
echo $letter;
?>
will only echo 'd' as it's response (rather than 'abcd'). I don't know
if this is meant to be the case, or if it is meant to err.
