I took yasmary at gmail dot com's function and updated it a little bit to give it a true
facebook style output (yesterday if 1 day ago, the day of the week if within the last week, and then
the month day and year (if necessary) for times greater than a week ago). I also tweaked it to
adjust the time according to a valid timezone string (DateTimeZone).
<?php
function time_ago($date,$timezone='America/Denver') {
if(empty($date)) {
return "No date provided";
}
$periods = array("second", "minute", "hour",
"day");
$lengths = array("60","60","24","7");
$now = time();
$unix_date = $date;
// check validity of date
if(empty($unix_date)) {
return "Bad date";
}
// state the tense
$tense = "ago";
for($j = 0; $difference >= $lengths[$j] && $j < count($lengths)-1; $j++) {
$difference /= $lengths[$j];
}
$difference = round($difference);
if($difference != 1) {
$periods[$j].= "s";
}
$return = "$difference $periods[$j] {$tense}";
/* If the return is days, we do some special processing */
if ($j == 3) {
// set the timezone using DateTime
$timezone = new DateTimeZone($timezone);
$dateTime = new DateTime();
$dateTime->setTimestamp($unix_date);
$dateTime->setTimezone($timezone);
$nowDateTime = new DateTime();
$nowDateTime->setTimestamp($now);
$nowDateTime->setTimezone($timezone);
if ($difference == 1) {
$return = 'Yesterday';
} else if ($difference <= 7) {
//$return = strftime('%A',$unix_date);
$return = $dateTime->format('l');
} else {
//if (strftime('%Y',$unix_time) == strftime('%Y',$now)) {
if ($dateTime->format('Y') == $nowDateTime->format('Y')) {
//$return = strftime('%B %e',$unix_date);
$return = $dateTime->format('F j');
} else {
//$return = strftime('%B %e, %Y',$unix_date);
$return = $dateTime->format('F j, Y');
}
}
//$return .= ' at '.strftime('%l:%M%P',$unix_date);
$return .= ' at '.$dateTime->format('g:ia');
}
return $return;
}
?>
And if you don't care about the timezone:
<?php
function time_ago($date) {
if(empty($date)) {
return "No date provided";
}
$periods = array("second", "minute", "hour",
"day");
$lengths = array("60","60","24","7");
$now = time();
$unix_date = $date;
// check validity of date
if(empty($unix_date)) {
return "Bad date";
}
// state the tense
$tense = "ago";
for($j = 0; $difference >= $lengths[$j] && $j < count($lengths)-1; $j++) {
$difference /= $lengths[$j];
}
$difference = round($difference);
if($difference != 1) {
$periods[$j].= "s";
}
$return = "$difference $periods[$j] {$tense}";
/* If the return is days, we do some special processing */
if ($j == 3) {
if ($difference == 1) {
$return = 'Yesterday';
} else if ($difference <= 7) {
$return = strftime('%A',$unix_date);
} else {
if (strftime('%Y',$unix_date) == strftime('%Y',$now)) {
$return = strftime('%B %e',$unix_date);
} else {
$return = strftime('%B %e, %Y',$unix_date);;
}
}
$return .= ' at '.strftime('%l:%M%P',$unix_date);
}
return $return;
}
?>
Returns look like this:
33 minutes ago
1 hour ago
Yesterday at 11:06am
Tuesday at 2:39pm
February 18 at 8:53pm
