How to convert Unix timestamp to Datetime in PHP

🎈 🎈 🎈


    $unixTimestamp = 1693468892;
    $date = date('Y-m-d H:i:s', $unixTimestamp);
    echo "Converted Date: " . $date;

Output:

Converted Date: 2023-08-31 08:01:32

Example only. There may be multiple ways to perform this operation.

Code Explanation

In this PHP code, the Unix timestamp 1693468892 is passed to the date() function along with the format string 'Y-m-d H:i:s'.
The format string specifies that the output should be in the format YYYY-MM-DD HH:MM:SS. The date() function converts the Unix timestamp into this human-readable date and time format and the resulting date, in this case 2023-08-31 08:01:32, is then printed.
