致命错误:Uncaught exception ' exception 'DateTime::__con - Fatal error: Uncaught exception 'Exception' with message 'DateTime::__construct(): Failed to parse time string

Fatal error: Uncaught exception 'Exception' with message 'DateTime::__construct(): Failed to parse time string

我得到这个错误

(!)致命错误:未捕获的异常' exception '与消息'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在第17行

当尝试这样做

//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。

这是我如何生成token_created_at, $time_gen = date('m-d-Y H:i:s ', time());。

传递的日期字符串不受DateTime解析器的支持。你必须使用createFromFormat创建一个DateTime对象。该方法允许您在创建新的DateTime对象时指定自定义格式:

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

如果你仍然得到一个错误，这意味着你的$token_created_at不是你指定的格式:

$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

我看到你的问题-格式字符串在s之后有一个空格。格式字符串必须与完全匹配:

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

更新了我的答案

function date_time( $date ) {
    if( $date == "" ){
        return "";
    } else {
        // echo $date;
        $my_date  = DateTime::createFromFormat( 'm-d-Y H:i:s', $date );
        // echo '<pre>';
        // print_r($my_date);
        // echo '</pre>';
        $new_date = $my_date->format( 'Y-m-d H:i:s' );
        return $new_date;
    }
}
$save = date_time('06-28-2014 07:43:58');
$my_dt = new DateTime( $save );
//Modify error
$expires_at = $my_dt->modify('+1 hour');
$expires_date = $my_dt->format( 'Y-m-d H:i:s' );
echo $expires_date;
//Return current time to match
$current_time = date('m-d-Y H:i:s', time());
echo $current_time;

试试这个:

$token_created_at = DateTime::createFromFormat("m-d-Y H:i:s", $token_created_at);
$my_dt = new DateTime($token_created_at->format('Y-m-d H:i:s'));
$expires_at = $my_dt->modify('+1 hour');

这将生成
