PHP时间过去了，在秒之前删除“和”

Question

So, I've got this working code which converts a MySQL date to UNIX Timestamp and subtracts it from the current date() to show a "time elapsed since X"-like timer. (the part which takes the date from database is missing since it's in another script)

    <?php 
    function time_elapsed($secs){
        $bit = array(
            ' year'        => $secs / 31556926 % 12,
            ' week'        => $secs / 604800 % 52,
            ' day'        => $secs / 86400 % 7,
            ' hour'        => $secs / 3600 % 24,
            ' minute'    => $secs / 60 % 60,
            ' second'    => $secs % 60
            );
        foreach($bit as $k => $v){
            if($v > 1)$ret[] = $v . $k . 's';
            if($v == 1)$ret[] = $v . $k;
            }
        array_splice($ret, count($ret)-1, 0, 'and');
        $ret[] = 'ago.';

        return join(' ', $ret);
        }

    $nowtime = time() + 10; //add 10s to avoid error
    $oldtime = strtotime($mysqltime2);

    $time_elapsed = time_elapsed($nowtime-$oldtime)."
";
    echo wordwrap($time_elapsed,35,"<br />
"); //split long line
    ?>

I managed to fix an error reporting missing array or something if the script was executed at the same time of the MySQL date by adding 10 seconds to the current timestamp.

Another issue I have is that the script shows "and X seconds" even if there aren't minutes/hours/days/etc before it. E.g. "and X seconds" "Y minutes and X seconds" "Z hours Y minutes and X seconds" "N days Z hours Y minutes and X seconds"

I want to remove the "and" before seconds ONLY if there's no minutes/hours/etc before it.

Any tip on how to fix this?

You could only splice when needed:

if( count($ret) > 1 ) {
    array_splice($ret, count($ret)-1, 0, 'and');
}
