选择年份 php的写法要比js简洁一些

<select type="text" class="form-control_2" name="years" id="years" >
<?php
$year = date('Y',time());
for($iadd=2005;$iadd<=2030;$iadd++){
if($year == $iadd){
$selected="selected";
}else{
$selected="";
}
echo "<option value='".$iadd."' ".$selected." >".$iadd."</option>";
}
?>
</select>
