在php中strtotime() 函数将任何英文文本的日期时间描述解析为 Unix 时间戳，这个函数也是我们经常会用到的，有需要的朋友参考一下。
语法
strtotime(time,now)参数 描述
time 规定要解析的时间字符串。
now 用来计算返回值的时间戳。如果省略该参数，则使用当前时间。
例子
| 代码如下 |
复制代码 |
<?php
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 |
Example #1 strtotime() 例子
| 代码如下 |
复制代码 |
<?php
echo strtotime("now"), "n";
echo strtotime("10 September 2000"), "n";
echo strtotime("+1 day"), "n";
echo strtotime("+1 week"), "n";
echo strtotime("+1 week 2 days 4 hours 2 seconds"), "n";
echo strtotime("next Thursday"), "n";
echo strtotime("last Monday"), "n";
?> |
Example #2 失败检查
| 代码如下 |
复制代码 |
<?php
$str = 'Not Good'; // previous to PHP 5.1.0 you would compare with -1, instead of false
if (($timestamp = strtotime($str)) === false) {
echo "The string ($str) is bogus";
} else {
echo "$str == " . date('l dS of F Y h:i:s A', $timestamp);
}
?> I just found out PHP thinks slashes in date-formats aren't very european:
(I guess this is not a bug, just the way it works. But correct me if I'm wrong.)
<?php $date = "06/10/2011 14:28"; // 6 october 2011 2:28 pm
$otherDate = "06-10-2011 14:28"; // 6 october 2011 2:28 pm
echo $stamp = strtotime($date) . "<br />"; // outputs 1307708880
echo $otherStamp = strtotime($otherDate) . "<br />"; // outputs 1317904080
echo date("d-m", $stamp); // outputs 10-06
echo date("d-m", $otherStamp); // outputs 06-10 ?> |
