1 minute instead of 1 minutes, 1 hour instead of 1 hours, etc.

The script works fine, but I need to modify it to show 1 minute ago instead of 1 minutes ago, 1 hour ago instead of 1 hours ago and 1 day ago instead of 1 days ago. I tried this and that, but couldn't get it working right.

$days = floor($diff/86400);
$hours = floor(($diff-$days*86400)/(60 * 60));
$min = floor(($diff-($days*86400+$hours*3600))/60);
$second = $diff - ($days*86400+$hours*3600+$min*60);

if($days > 0) echo $days." days ago";
elseif($hours > 0) echo $hours." hours ago";
elseif($min > 0) echo $min." minutes ago";
else echo "Just now";

Code (markup):

 

You could just put the plural into a greater than one condition.

<?php

    $days = floor( $diff / 86400 );
    $hours = floor( ( $diff - $days * 86400 ) / 3600 );
    $min = floor( ( $diff - ( $days * 86400 + $hours * 3600 ) ) / 60 );
    $second = $diff - ( $days * 86400 + $hours * 3600 + $min * 60 );

    if ( $days )
        echo "$days day". ( $days > 1 ? 's' : '' ) ." ago";
    elseif ( $hours )
        echo "$hours hour". ( $hours > 1 ? 's' : '' ) ." ago";
    elseif ( $min )
        echo "$min minute". ( $min > 1 ? 's' : '' ) ." ago";
    else
        echo 'Just now';

?>
