year函数 有关问题，在线给分

year函数 问题，在线给分

如$year=过的年数，如５
$staff_join=开始的年月日　如2008-05-02
我现要　把开始的年月日加上年数，如　2008-05-02＋5＝2013-05-02　用什么表达式呀，
要可运行的代码，谢谢

小弟这样　（$Begin=(date("Y",$staff_join)+$year)　出错，　输出1970）

------解决方案--------------------

PHP code

<?php $year = 5;
$staff_join ="20010-05-02";
$a = strtotime("+".$year." Year")-time(); 
$staff_join = strtotime($staff_join)+$a;
echo date('Y-m-d',$staff_join);
?>
<br><font color="#e78608">------解决方案--------------------</font><br>这里赋值写错了<br>$staff_join ="20010-05-02";<br>改成$staff_join ="2010-05-02";
<br><font color="#e78608">------解决方案--------------------</font><br>

PHP code

$year = 5;
$staff_join = '2008-05-02';
$arrdate= explode('-',$staff_join);
$arrdate[0] += $year;
$staff_out = implode('-',$arrdate);
echo $staff_out; //2013-05-02
echo "<br>";
echo $arrdate[0]; //2013
?>

------解决方案--------------------

PHP code

<?php $value = 5;
$year = date('Y');
$year += $value;
echo $year.date('-m-d');
<br /><font color="#e78608">------解决方案--------------------</font><br>$year = 5;  <br>$staff_join = '2008-05-02';<br><br>$Begin = date("Y-m-d", strtotime("+$year year $staff_join));<br>
<br><font color="#e78608">------解决方案--------------------</font><br>给楼上老大改下<br><?php   <br />$year = 5;  <br>$staff_join = '2008-05-02';  <br><br>$Begin = date("Y-m-d", strtotime("+$year year $staff_join"));  <br>echo $Begin;<br>?>
