How to Convert Timestamps to Human-Readable Relative Dates and Times in PHP?

Converting Timestamps to Relative Date/Time

In PHP, you can easily convert timestamps to user-friendly relative date/time strings that work for both past and future timestamps. By adapting timestamps to this format, you can enhance the user experience by providing intuitive time representations.

To accomplish this conversion, you can utilize the following function:

function time2str($ts)
{
    // Handle non-numeric timestamps
    if (!ctype_digit($ts)) {
        $ts = strtotime($ts);
    }

    $diff = time() - $ts;

    // Handle current time
    if ($diff == 0) {
        return 'now';
    }

    // Handle past timestamps
    if ($diff > 0) {
        $day_diff = floor($diff / 86400);
        if ($day_diff == 0) {
            // Handle minutes and hours ago
            if ($diff < 60) {
                return 'just now';
            } elseif ($diff < 120) {
                return '1 minute ago';
            } elseif ($diff < 3600) {
                return floor($diff / 60) . ' minutes ago';
            } elseif ($diff < 7200) {
                return '1 hour ago';
            } elseif ($diff < 86400) {
                return floor($diff / 3600) . ' hours ago';
            }
        } elseif ($day_diff == 1) {
            return 'Yesterday';
        } elseif ($day_diff < 7) {
            return $day_diff . ' days ago';
        } elseif ($day_diff < 31) {
            return ceil($day_diff / 7) . ' weeks ago';
        } elseif ($day_diff < 60) {
            return 'last month';
        } else {
            return date('F Y', $ts);
        }
    }

    // Handle future timestamps
    else {
        $diff = abs($diff);
        $day_diff = floor($diff / 86400);
        if ($day_diff == 0) {
            // Handle minutes and hours from now
            if ($diff < 120) {
                return 'in a minute';
            } elseif ($diff < 3600) {
                return 'in ' . floor($diff / 60) . ' minutes';
            } elseif ($diff < 7200) {
                return 'in an hour';
            } elseif ($diff < 86400) {
                return 'in ' . floor($diff / 3600) . ' hours';
            }
        } elseif ($day_diff == 1) {
            return 'Tomorrow';
        } elseif ($day_diff < 4) {
            return date('l', $ts);
        } elseif ($day_diff < 7 + (7 - date('w'))) {
            return 'next week';
        } elseif (ceil($day_diff / 7) < 4) {
            return 'in ' . ceil($day_diff / 7) . ' weeks';
        } elseif (date('n', $ts) == date('n') + 1) {
            return 'next month';
        } else {
            return date('F Y', $ts);
        }
    }
}

By using this function, you can easily generate user-friendly relative date/time strings from timestamps.
