function DateDiff($date1,$date2,$unit="d"){ 

switch ($unit) {

case 's':

$dividend = 1;

break;

case 'i':

break;

case 'h':

$dividend = 60*60;

break;

case 'd':

$dividend = 60*60*24;

break;

case 'm':

$dividend = 60*60*24*30;

break;

default:

$dividend = 60*60*24;

}

$time1 = strtotime($date1);

$time2 = strtotime($date2);

if ($time1 && $time2){

return ceil(($time1 - $time2) / $dividend);

}else{

return false;

}

使用： 
echo DateDiff('2009-08-30 12:12:12','2009-08-23 12:50:22','h');

dateadd( )

function DateAdd($date,$int,$unit="d"){ 

if(strpos($date," ")){

$temp=explode(" ",$date);

$dateArr1=explode("-",$temp[0]);

$dateArr2=explode(":",$temp[1]);

}else{

return "这不是一个标准的Y-m-d H:i:s格式日期";

}

$value[$unit]=$int;

$newDate=mktime($dateArr2[0]+$value['h'],$dateArr2[1]+$value['i'],$dateArr2[2]+$value['s'],$dateArr1[1]+$value['m'],$dateArr1[2]+$value['d'],$dateArr1[0]+$value['y']);

return date("Y-m-d H:i:s",$newDate);

}

使用： 
echo now()."
".DateAdd(now(),30,"m");

response.redirect 可以至于页面任何地方，跳转之前不会再往下执行代码

php");

header必须至于页面顶部，header跳转之前仍会执行下面的代码，需要加break; 才能打断执行

response.end

exit(1) 退出当前一层程序

mkdir($target_path);

foreach (scandir($dir_path) as $file){

if($file=='.'||$file=='..')continue;

if(is_dir($dir_path.'/'.$file)) copy_dir($dir_path.'/'.$file,$target_path.'/'.$file);//递归
