Next, let us learn how to use PHP to format local time and date!

PHP format local time/date

Formatting local time and date is a common task in php and can be accomplished through PHP's built-in functions and classes.

Built-in functions

PHP provides several built-in functions to format time and date:

• date(): Used to format the current time and date and return the result according to the provided format string .
• strftime(): Similar to date(), but it uses POSIX's strftime() function to provide more advanced formatting options.

Format parameters

The

date() and strftime() functions both accept a format string parameter that specifies how the output should be formatted. The format string contains special characters, called conversion specifiers, that specify specific date and time elements to be displayed.

The following are commonly used conversion specifiers:

• %Y: Year (four digits)
• %y: Year (two digits)
• %m: month (two digits)
• %d: Day (two digits)
• %H: hour (24-hour format)
• %I: hour (12-hour clock)
• %M: Minutes
• %S: seconds

Time zone processing

By default, date() and strftime() return a time and date based on the current server time zone. To specify a different time zone, you can use the date_default_timezone_set() function.

For example:

date_default_timezone_set("America/Los_Angeles");

This will set the time zone to Los Angeles, USA time zone.

Custom formatting

In addition to the built-in conversion specifiers, custom formatting strings can be used to create more complex formats. Custom formatting strings can contain a combination of text and conversion specifiers.

For example, to format a date as "Monday, March 6, 2023", you can use the following code:

echo "week" . date("w") . "," . date("Y year m month d day");

PHP Intl Extension

PHP Intl extension provides more advanced time and date formatting options. It includes an IntlDateF<strong class="keylink">ORM</strong>atter class which allows more complex and localizable formatting of times and dates.

For example, to format a date as "Monday, March 6, 2023" using the local language and date format, you would use the following code:

$formatter = new IntlDateFormatter(
"en-US",
IntlDateFormatter::FULL,
IntlDateFormatter::FULL,
"America/Los_Angeles",
IntlDateFormatter::GREGoRIAN
);
$formattedDate = $formatter->format(time());
echo $formattedDate;

Method of choosing

Which formatting method to choose depends on the degree and complexity of formatting required. For simple formatting, the built-in functions date() and strftime() are usually sufficient. For more advanced or localized formatting, the PHP Intl extension provides more options.
