致命错误:未捕获的异常 'Exception' 带有消息 'DateTime::__constr

问题描述

我收到这个错误

( ! ) 致命错误:未捕获的异常 'Exception' 带有消息 'DateTime::__construct(): 无法解析位置 0 (0) 处的时间字符串 (06-28-2014 07:43:58):意外字符' 在/Users/matt/Desktop/Likes/forgot/activate.php 第 17 行

( ! ) Fatal error: Uncaught exception 'Exception' with message 'DateTime::__construct(): Failed to parse time string (06-28-2014 07:43:58 ) at position 0 (0): Unexpected character' in /Users/matt/Desktop/Likes/forgot/activate.php on line 17

尝试这样做时

//DB query
$stmt = $con->prepare("SELECT token_created_at from reset WHERE token = :urltoken");
$stmt->bindValue(':urltoken', $_GET['token']);
$stmt->execute();
$stmt->setFetchMode(PDO::FETCH_ASSOC);
while($row = $stmt->fetch()) {
     $token_created_at = $row['token_created_at'];
}

//Remove after testing
echo $token_created_at;

$my_dt = new DateTime($token_created_at);

//Modify error
$expires_at = $my_dt->modify('+1 hour');

//Return current time to match
$current_time = date('m-d-Y H:i:s ', time());

第 17 行是 $my_dt = new DateTime($token_created_at); 这是我的时间格式 06-28-2014 07:43:58.

Line 17 is $my_dt = new DateTime($token_created_at); and this is my time format 06-28-2014 07:43:58.

这就是我生成token_created_at的方式，$time_gen = date('m-d-Y H:i:s ', time());.

This is how I generate token_created_at, $time_gen = date('m-d-Y H:i:s ', time());.

推荐答案

您传递的日期字符串是 不支持 DateTime 解析器.您必须使用 createFromFormat 创建一个 DateTime 对象.此方法允许您在创建新的 DateTime 对象时指定自定义格式:

The date string you're passing is not supported by the DateTime parser. You must create a DateTime object by using createFromFormat. This method allows you to specify the custom format when creating a new DateTime object:

$my_dt = DateTime::createFromFormat('m-d-Y H:i:s', $token_created_at);

如果您仍然收到错误，这意味着您的 $token_created_at 不是您指定的格式:

If you're still getting an error that means that your $token_created_at is not in the format you specified:

$now = date('m-d-Y H:i:s'); //string(19) "06-28-2014 15:00:47"

var_dump(DateTime::createFromFormat('m-d-Y H:i:s', $now));
object(DateTime)#1 (3) {
  ["date"]=>
  string(19) "2014-06-28 15:00:47"
  ["timezone_type"]=>
  int(3)
  ["timezone"]=>
  string(13) "Europe/Berlin"
}

编辑

我看到您的问题 - 格式字符串在 s 之后有一个空格.格式字符串必须完全匹配:

I see your problem - the format string has a space after s. The format strings must match exactly:

$my_dt = DateTime::createFromFormat('m-d-Y H:i:s ', $token_created_at);
