PHP时间戳与日期之间转换

php and use Can exist accomplish us Replace with date time want change Convert

在php中如果要实现日期转换成时间戳我们可以直接使用strtotime函数,如果把时间戳转换成日期直接使用date()函数即可实现,下面我来给各们朋友介绍介绍。

strtotime()函数 strtotime() 函数将任何英文文本的日期时间描述解析为 Unix 时间戳。


例子

 代码如下 复制代码

echo(strtotime("now"));
echo(strtotime("3 October 2005"));
echo(strtotime("+5 hours"));
echo(strtotime("+1 week"));
echo(strtotime("+1 week 3 days 7 hours 5 seconds"));
echo(strtotime("next Monday"));
echo(strtotime("last Sunday"));
?>

输出:

1138614504
1128290400
1138632504
1139219304
1139503709
1139180400
1138489200

上面是把日期转换成时间戳了,我们也可以把如 2013-04-21这种转换成时间戳

 代码如下 复制代码

$a = date();
$mk = strtotime($a)

要求只能在白天8:00-20:00发送短信,怎么样获得到每天的这段时间区间?

 代码如下 复制代码



$y=date("Y",time());
$m=date("m",time());
$d=date("d",time());
$start_time = mktime(9, 0, 0, $m, $d ,$y);
$end_time = mktime(19, 0, 0, $m, $d ,$y);

$time = time();
if($time >= $start_time && $time {
// do something....
}
?>


下面来介绍把时间戳转换成日期


date()函数,

此函数不但可以获取各种各样的时间日期之外,还可以进行日期转换呼

 代码如下 复制代码


$time = time();
$date = date("Y-m-d",$time);
echo 'www.bKjia.c0m 提示'.$date
?>

这样就输出 www.bKjia.c0m 提示 2013-04-21 。
