php strtotime()函数时间日期转换

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
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

$str = 'Not Good'; // previous to PHP 5.1.0 you would compare with -1, instead of false if (($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.)     $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) . " "; // outputs 1307708880     echo $otherStamp = strtotime($otherDate) . " "; // outputs 1317904080         echo date("d-m", $stamp); // outputs 10-06     echo date("d-m", $otherStamp); // outputs 06-10 ?>
