如何在select标签中仅显示数组的唯一值作为选项？

Question

Consider this array:

$yrs = array(2015,2014,2015,2013,2015,2014);

I need to display only the unique value inside a combo box.

I tried:

print_r(array_unique($yrs));

But it displays it like this:

Array ( [0] => 2015 [1] => 2014 [3] => 2013 )

I need to have only 2015, 2014, 2013 inside the combo box. How can i extract only these values?

My code:

<?php
    $yrs = array(2015,2014,2015,2013,2015,2014);
?>

<select name="yrs">
<?php

    echo "<option>";
    echo implode(",",array_unique($yrs));  //here it displays in same option 
    echo "</option>";

?>
</select>

I need to get 2015 2014 2013 each in different options.

$yrss=array_unique($yrs);
foreach ($yrss as $key=>$value) 
{ 
echo "<option>"; 
echo $value; 
echo "</option>"; 
}
