PHP timezone_name_from_ abbr() function (with example)

Hey there!

I stumbled upon your question about the `timezone_name_from_abbr()` function and thought I could provide some insight based on my previous encounter with it.

In my case, I was working on a project that required displaying dates and times in different time zones. Initially, I had a similar confusion about how to use `timezone_name_from_abbr()` effectively, but with a bit of trial and error, I figured it out.

To give you a clearer understanding, let me share a practical example. Suppose you have a time zone abbreviation of "EST" and you need to retrieve the full name. Here's how you can achieve that:

php
$abbreviation = 'EST';

$offset = -18000; // Offset for Eastern Standard Time in seconds

$dst = false; // No daylight saving time



$fullTimeZoneName = timezone_name_from_abbr($abbreviation, $offset, $dst);

if ($fullTimeZoneName) {

    echo "The full name of the time zone is: " . $fullTimeZoneName;

} else {

    echo "Unable to determine the full name of the time zone.";

}

Hey there [Your Name],

I recently came across your question and thought I could share my experience with the `timezone_name_from_abbr()` function. I had a similar requirement in one of my projects, and using this function proved to be quite useful.

To start, let me explain how `timezone_name_from_abbr()` works. This function takes three parameters: the abbreviation of the time zone, the offset in seconds from UTC, and whether daylight saving time is active. It then returns the long-form name of the time zone if a match is found; otherwise, it returns `false`.

Here's an example of how you could use this function:

php
$abbreviation = 'PST';

$offset = -28800; // Offset for Pacific Standard Time in seconds

$dst = false; // No daylight saving time



$timeZoneName = timezone_name_from_abbr($abbreviation, $offset, $dst);

if ($timeZoneName !== false) {

    echo "The full name of the time zone is: " . $timeZoneName;

} else {

    echo "Unable to determine the full name of the time zone.";

}

Hello there!

I came across your query regarding the `timezone_name_from_abbr()` function in PHP and thought I could share my personal experience with you.

In one of my previous projects, I encountered a similar need to convert abbreviated time zone names into their full names. The `timezone_name_from_abbr()` function proved to be quite handy for this task.

To give you a practical example, suppose you have the abbreviation "GMT" and you want to retrieve the corresponding full time zone name. Here's an illustration of how you can utilize the function:

php
$abbreviation = 'GMT';

$offset = 0; // GMT has an offset of 0 seconds from UTC

$dst = false; // No daylight saving time



$fullTimeZoneName = timezone_name_from_abbr($abbreviation, $offset, $dst);

if ($fullTimeZoneName !== false) {

    echo "The full name of the time zone is: " . $fullTimeZoneName;

} else {

    echo "Unable to determine the full name of the time zone.";

}
