PHP - DateTime :: createFromFormat похоже не найти шаблон

Question

У меня есть следующая дата: (Tue 7:00AM EST).

Теперь, чтобы изменить его формат на 2014-01-21 7:00, я использовал DateTime:createFromFormat() и DateTime::format(). Однако он, похоже, не находит шаблон в упомянутой выше строке.

Вот код:

<?php 

$date = DateTime::createFromFormat('(D g:iA T)', '(Tue 7:00AM EST)'); 
if($date !== false) { 
    var_dump($date->format('Y-m-d H:i')); 
} else { 
    echo 'Invalid date!'; 
} 

?> 

Prints: Invalid Date! 

Answer 1

Подрезать скобки:

$date = DateTime::createFromFormat('D g:iA T', trim('(Tue 7:00AM EST)', '()')); 

Answer 2

print_r(DateTime::getLastErrors(),1); дал мне:

Array ( [warning_count] => 0 [warnings] => Array ( )

[error_count] => 1 
[errors] => Array 
    (
     [16] => Data missing 
    ) 

)

, что означает по индексу 16 строки «(вт 7 : 00AM EST) 'отсутствуют данные (в последней скобке).

echo print_r(DateTimeZone::listIdentifiers()); перечислены следующие TimeZones

Так что не EST перечислены. Однако $date = DateTime::createFromFormat('T', 'EST'); работает без проблем, в отличие от $date = DateTime::createFromFormat('(T)', '(EST)');.

Мне не удалось получить именно этот пример, но, возможно, мои упомянутые мысли могут вам помочь.

КСТАТИ: Следующие работал для меня:

• Раскрыв скобки (возможно, самое простое решение)
• $date = DateTime::createFromFormat('(D g:iA)', '(Tue 7:00AM)'); (без часового пояса)

Answer 3

Вам не нужно отсечь скобки, ваш формат даты может быть проанализирован на \DateTime::createFromFormat() без каких-либо проблем: -

$dateStr = "(Tue 7:00AM EST)"; 
$date = \DateTime::createFromFormat("(D g:iA T", $dateStr); 
var_dump($date); 

Вы заметите, что этот трюк состоит в том, чтобы опустить конец ).

Выход: -

object(DateTime)[1] 
    public 'date' => string '2014-01-21 07:00:00' (length=19) 
    public 'timezone_type' => int 2 
    public 'timezone' => string 'EST' (length=3) 

See it working и руководство для formats accepted by DateTime::createFromFormat().
