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:
<?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:
<?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:
<?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//开源代码phprm.com echo date("d-m", $stamp); // outputs 10-06 echo date("d-m", $otherStamp); // outputs 06-10
