PHP is a widely used server-side programming language, and its timestamp to time function is very practical. However, when we need to consider different time zones, we need to add time zone conversion based on the timestamp. In this article, we will discuss how to convert timestamp to time in different time zones in PHP.

  1. Understand the concept of time zone

Before performing time conversion, we need to clarify the concept of time zone. A time zone refers to the rule that everyone in a region uses the same standard time. Usually each time zone has a representative city, such as UTC-8 for the Los Angeles time zone.

  1. Get the current timestamp

The function to get the current timestamp in PHP is time(), which returns the current system time and UTC time in January 1970 The difference in seconds between 0 hour, 0 minute and 0 second on the 1st.

For example:

$timestamp = time();
  1. Convert to the specified time zone

Before converting the timestamp to the time in the specified time zone, you need to determine the target time zone first, and then Convert the current timestamp to a timestamp in that time zone, and finally use PHP's date() function to format it into the required time format.

For example, convert the current timestamp to Beijing time (CST):

$timestamp = time();
$target_timezone = new DateTimeZone('Asia/Shanghai');
$date_time = new DateTime('@' . $timestamp);
$date_time->setTimeZone($target_timezone);
$beijing_time = $date_time->format('Y-m-d H:i:s');
echo $beijing_time;

The explanation of this code is as follows:

  • Line 1 gets the current timestamp .
  • Line 2 creates a DateTimeZone object representing the target time zone.
  • Line 3 creates a DateTime object with the current timestamp as a parameter.
  • Line 4 sets the DateTime object to the target time zone.
  • Line 5 formats the DateTime object into a string in the format of "Y-m-d H:i:s", that is, year-month-day hour: minute: second.
  • Line 6 outputs the formatted Beijing time.
  1. List available time zones

When using the DateTimeZone object, you need to pass in the correct time zone identifier. We can use the static method listIdentifiers() of the DateTimeZone class to list the identifiers of all available time zones.

For example:

$timezones = DateTimeZone::listIdentifiers();
foreach ($timezones as $timezone) {
    echo $timezone . '<br>';
}

The explanation of this code is as follows:

  • Line 1 calls the listIdentifiers() method of the DateTimeZone class and returns a list containing all available time zone identifiers array of symbols.
  • Lines 2-4 use a foreach loop to traverse all time zone identifiers and output them to the page.

Summary

This article explains how to convert timestamps to times in different time zones in PHP. First you need to understand the concept of time zone, and then use the DateTime and DateTimeZone classes to convert. Also, it is recommended to list all available time zone identifiers to facilitate selection of the correct time zone. I hope this article will be helpful for everyone to learn PHP time conversion.
