Writing a PHP function that converts UK date to relative time
What would be the best way of converting UK date and time in the format:
30/01/2013 13:30:06
which is d/m/YH:i:s in PHP noation to relative time (ie just now, few minutes ago, 30 minutes ago, 3 hours ago, 1 day ago.. and so on). I've seen several tutorials on the subject but they all revolve around creating functions without any clear explanations. I would appreciate some assistance on the matter.
希望这可以帮助
function timeSince($ptime){
$etime = time() - strtotime($ptime);
if( $etime < 1 ){
return 'less than 1 second ago';
}
$a = array( 12 * 30 * 24 * 60 * 60 => 'year',
30 * 24 * 60 * 60 => 'month',
24 * 60 * 60 => 'day',
60 * 60 => 'hour',
60 => 'minute',
1 => 'second'
);
foreach( $a as $secs => $str ){
$d = $etime / $secs;
if( $d >= 1 ){
$r = round( $d );
return ' <font style="color:#0099ff"> ' . $r . ' ' . $str . ( $r > 1 ? 's' : '' ) . ' ago</font>';
}
}
}
Writing a custom function might help. Cut the string and convert to numbers. Use mktime() to create a timestamp, compare it to time() current timestamp and switch (case) through various relative time possibilities.
Use mktime(); and date();
For example if you have a specific time in the format d/m/YH:i:s , and you want it as dmY H:s:i , you would explode the time into chunks using explode(); and then use date(new_format, mktime(current_format_chunks))
