php生成年月日下载列表的方法

本文实例讲述了php生成年月日下载列表的方法。分享给大家供大家参考。具体实现方法如下：

function mdy($mid = "month", $did = "day", $yid = "year", $mval, $dval, $yval)
{
  if(empty($mval)) $mval = date("m");
  if(empty($dval)) $dval = date("d");
  if(empty($yval)) $yval = date("y");
  $months = array(1 => "january", 2 => "february", 3 => "march", 4 => "april", 5 => "may", 6 => "june", 7 => "july", 8 => "august", 9 => "september", 10 => "october", 11 => "november", 12 => "december");
  $out = "<select name='$mid' id='$mid'>";
  foreach($months as $val => $text)
    if($val == $mval) $out .= "<option value='$val' selected>$text</option>";
    else $out .= "<option value='$val'>$text</option>";
  $out .= "</select> ";
  $out .= "<select name='$did' id='$did'>";
  for($i = 1; $i <= 31; $i++)
    if($i == $dval) $out .= "<option value='$i' selected>$i</option>";
    else $out .= "<option value='$i'>$i</option>";
  $out .= "</select> ";
  $out .= "<select name='$yid' id='$yid'>";
  for($i = date("y"); $i <= date("y") + 2; $i++)
    if($i == $yval) $out.= "<option value='$i' selected>$i</option>";
    else $out.= "<option value='$i'>$i</option>";
  $out .= "</select>";
  return $out;
}
