如何在PHP中分隔日期，时间和时区？

Question

The date value which is coming from API is "2015-12-16T22:14:26-0700" now i need to convert the date into "2015-12-16 22:14:26" without using DateTime object. To do that i am trying to match the timezone -0700 in the end and trying split the date into "2015-12-16" , "22:14:26" , "-0700" the below code is returning an array. please let me know where i did wrong here.

the same i have to do if the date is coming in

"2015-12-17 07:00:00 Etc/GMT" in this format as well.

preg_match("/.*?([-+]d+)$/", "2015-12-16T22:14:26-0700", $timeZone);
print_r($timeZone);

Answer 1

This should split your string.

preg_match("/(\d{4}-\d{1,2}-\d{1,2})T(\d{1,2}:\d{1,2}:\d{1,2})(-?\d{4})/", "2015-12-16T22:14:26-0700", $timeZone);

Output:

Array
(
    [0] => 2015-12-16T22:14:26-0700
    [1] => 2015-12-16
    [2] => 22:14:26
    [3] => -0700
)

Your current regex would only capture the timezone offset; if your meta-character for numbers was corrected to include a backslash, as is d+ is allowing multiple ds. Functional demo of your regex, https://regex101.com/r/yJ0lV5/2.
