日期時間我有這樣的代碼:警告使用PHP
try{
$datetime1 = new DateTime("now");
$datetime2 = new DateTime("now");
$interval = $datetime1->diff($datetime2);
var_dump($interval);
}
catch(Exception $e) {
echo $e->getMessage();
}
我沒有看到任何結果關於var_dump
,PHP的輸出是:
DateTime::__construct(): It is not safe to rely on the system's timezone setting
s. You are *required* to use the date.timezone setting or the date_default_timez
one_set() function. In case you used any of those methods and you are still gett
ing this warning, you most likely misspelled the timezone identifier. We selecte
d 'Europe/Paris' for '1.0/no DST' instead
我使用php_cli 5.3。 8
我該怎麼辦? 感謝
錯誤消息提示通過編程解決方案。加上一個用於暗示不涉及代碼修改的解決方案,這將導致更多的可移植代碼。 – davogotland 2012-01-12 12:43:35
