Question

我有以下代码。我也记录了输出：

function convertGeneralAvailabilityTime($date,$from_timezone,$from_timebegin, $from_time$
{
echo "$date,$from_timezone,$from_timebegin, $from_timeend, $to_timezone"; 
// 2010-09-19,America/New_York,07:45:00, 08:00:00, America/Los_Angeles

$tz1 = new DateTimezone($from_timezone);

$datetime1 = new DateTime("$date $from_timebegin", $tz1);
$datetime2 = new DateTime("$date $from_timeend", $tz1);

echo "$date $from_timebegin";
// 2010-09-19 07:45:00
echo "$date $from_timeend";
// 2010-09-19 08:00:00
var_export($tz1);
//DateTimeZone::__set_state(array(
//))
var_export($datetime1);
//DateTime::__set_state(array(
//))

我的php的DateTime（）函数出了问题 - 但我无法理解！我在这台服务器上使用PHP 5.2.14。

编辑1：抱歉，误解了一些PHP输出 - 在上面更正了

编辑2：我有以下测试文件，它给出了如下的确切输出

<?php
$date = '2010-09-19';
$from_timezone = 'America/New_York';
$from_timebegin = '07:45:00';
$from_timeend = '08:00:00';
$to_timezone = 'America/Los_Angeles'; // Trimmed 2010-09-19 07:45:002010-09-19

$tz1 = new DateTimezone($from_timezone);

$datetime1 = new DateTime("$date $from_timebegin", $tz1);
$datetime2 = new DateTime("$date $from_timeend", $tz1);

echo "$date $from_timebegin".PHP_EOL;
echo "$date $from_timeend".PHP_EOL;
var_dump($tz1);
var_dump($datetime1);

?>

输出：

jailshell-3.2$ php dttest.php
2010-09-19 07:45:00
2010-09-19 08:00:00
object(DateTimeZone)#1 (0) {
}
object(DateTime)#2 (0) {
}

编辑3 - 如果有帮助，我的phpinfo也会显示

date
date/time support   enabled
"Olson" Timezone Database Version   2010.12
Timezone Database   external
Default timezone    America/Chicago

Answer 1

在创建DateTime对象之前声明您的默认时区，例如。

date_default_timezone_set('America/New_York');
$tz1 = new DateTimezone($from_timezone);
$datetime1 = new DateTime("$date $from_timebegin", $tz1);
$datetime2 = new DateTime("$date $from_timeend", $tz1);

或者在你的php.ini文件中使用date.timezone =“America / New_York”声明它

Answer 2

我简化并运行了你的代码。这是输出：

php > $date = '2010-09-19';
php > $from_timezone = 'America/New_York';
php > $from_timebegin = '07:45:00';
php > $from_timeend = '08:00:00';
php > $to_timezone = 'America/Los_Angeles'; // Trimmed 2010-09-19 07:45:002010-09-19 08:00:00
php > 
php > $tz1 = new DateTimezone($from_timezone);
php > 
php > $datetime1 = new DateTime("$date $from_timebegin", $tz1);
php > $datetime2 = new DateTime("$date $from_timeend", $tz1);
php > 
php > echo "$date $from_timebegin".PHP_EOL;
2010-09-19 07:45:00
php > echo "$date $from_timeend".PHP_EOL;
2010-09-19 08:00:00
php > var_dump($tz1);
object(DateTimeZone)#1 (0) {
}
php > var_dump($datetime1);
object(DateTime)#2 (3) {
  ["date"]=>
  string(19) "2010-09-19 07:45:00"
  ["timezone_type"]=>
  int(3)
  ["timezone"]=>
  string(16) "America/New_York"
}

我没有看到问题。

顶部的回声包含末尾的垃圾（时区之后）

echo "$date,
      $from_timezone,
      $from_timebegin, 
      $from_timeend, 
      $to_timezone"
;

// 2010-09-19,
// America/New_York,
// 07:45:00, 
// 08:00:00, 
// America/Los_Angeles2010-09-19 07:45:002010-09-19 08:00:00

最后还有什么额外的东西？

Answer 3

$datetime1 = new DateTime($date $from_timebegin, $tz1);
$datetime2 = new DateTime($date $from_timeend, $tz1);

echo $date $from_timebegin;

echo $date $from_timeend;

在PHP中创建新的DateTime对象不起作用
