How Can I Calculate and Display the Time Elapsed Since a DateTime Stamp in PHP?

Determining Time Elapsed Since a DateTime Stamp in PHP

In PHP, obtaining the time passed since a specific date and time stamp is crucial. This information can be useful in displaying elapsed time in a user-friendly format, such as "xx Minutes Ago" or "xx Days Ago."

Solution:

The provided code exemplifies an effective approach to convert a date and time stamp into a relative time format:

<?php
$timestamp = strtotime('2010-04-28 17:25:43');

function humanTiming($timestamp) {
    $difference = time() - $timestamp;
    $tokens = array(
        31536000 => 'year',
        2592000 => 'month',
        604800 => 'week',
        86400 => 'day',
        3600 => 'hour',
        60 => 'minute',
        1 => 'second'
    );

    foreach ($tokens as $unit => $text) {
        if ($difference < $unit) continue;
        $units = floor($difference / $unit);
        return $units . ' ' . $text . (($units > 1) ? 's' : '');
    }
}

echo 'Event occurred ' . humanTiming($timestamp) . ' ago';
?>

Explanation:

• The strtotime() function converts the provided date and time stamp ('2010-04-28 17:25:43') into a UNIX timestamp.
• The humanTiming() function calculates the difference between the current time and the timestamp.
• The function then iterates over an array of time units (year, month, week, etc.) and their corresponding text representations.
• It checks if the time difference is greater than or equal to the current unit and returns the appropriate text representation.
• Finally, the returned string is appended to the output, indicating the relative time elapsed since the timestamp.
