The drop down menu appears, but is blank, and has no options.
<?php
session_start();
//if the session data has been set, then the variable $sv_02 is defined
//as the data held in the session under that name, otherwise it is blank
if (isset($_SESSION['sv_02'])) {$sv_02=$_SESSION['sv_02'];} else {$sv_02="";}
//define the array
$dm_sv_02 = array('-Year','-2012','-2011','-2010','-2009');
//create the function
function dropdown($dropdownoptions, $session_data)
{
foreach($dropdownoptions as $dropdownoption){
if($session_data == $dropdownoption){
echo '<option value="' . $dropdownoption . '" selected>' . $dropdownoption . '</option>';
} else {
echo '<option value="' . $dropdownoption . '">' . $dropdownoption . '</option>';
}
}
}
//echo the HTML needed to create a drop down, and populate it with
//the function which should create the <option> elements
echo '<select name="sv_02">';
dropdown($dm_sv_02, $sv_02);
echo '</select>';
?>

I tested your code and it works fine for me. It outputs (I added line breaks for readability):
<select name="sv_02">
<option value="-Year">-Year</option>
<option value="-2012">-2012</option>
<option value="-2011">-2011</option>
<option value="-2010">-2010</option>
<option value="-2009">-2009</option>
</select>
Works fine for me.
Alternative (taking the echo out of the function):
<?php
session_start();
//if the session data has been set, then the variable $sv_02 is defined
//as the data held in the session under that name, otherwise it is blank
if (isset($_SESSION['sv_02'])) {$sv_02=$_SESSION['sv_02'];} else {$sv_02="";}
//define the array
$dm_sv_02 = array('-Year','-2012','-2011','-2010','-2009');
//create the function function
dropdown($dropdownoptions, $session_data)
{
$str='';
foreach($dropdownoptions as $dropdownoption){
if($session_data == $dropdownoption){
$str .= '<option value="' . $dropdownoption . '" selected>' . $dropdownoption . '</option>';
} else {
$str .= '<option value="' . $dropdownoption . '">' . $dropdownoption . '</option>';
}
$str .= "\
";
}
return $str;
}
//echo the HTML needed to create a drop down, and populate it with
//the function which should create the <option> elements
?>
<form>
<select name="sv_02">
<?php
echo dropdown($dm_sv_02, $sv_02);
?>
</select>
</form>
