php strtotime()函数时间日期转换

作者：袖梨 2022-06-24

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
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

?>
