Your array is defined in the variable $n, so you must access it in the foreach using the same variable.
Also, nothing will happen if you don't output anything.

Code:

<?php

$v;  #<-- doesn't do anything.

$n = array("AP","UP","TN","GJ");

foreach($n as $key => $value)
{
    echo $value."<br />";
}

// Same thing as saying:

foreach($n as $value)
{
    echo $value."<br />";
}

?>
