我修改了一个脚本，从时间戳中获取相对日期（x次之前），我想对它进行调整，以添加另一个精度级别，如"昨天"或"前天"。
试过这个，它有效，但不是很干净，你知道我如何在"最近几天"之后简化这两行吗？
function relativedate($timestamp, $limit = 1209600){
$diff = time() - $timestamp;
$time = ($diff < 1) ? 1 : $diff;
$times = array(
"year" => 31536000,
"month" => 2592000,
"week" => 604800,
"day" => 86400,
"hour" => 3600,
"minute" => 60,
"second" => 1
);
// Date limit as displayed full
if ($limit > 0 && $diff > $limit){
return "on ".date("d/m/Y - H:i:s", $timestamp);
}
// Recent days
if ($diff > $times["day"] && $diff < ($times["day"] * 2)-1) return "yesterday";
if ($diff > ($times["day"] * 2) && $diff < ($times["day"] * 3)-1) return "the day before yesterday";
// Display x time ago
foreach ($times as $unit => $seconds){
if ($time < $seconds) continue;
$amount = floor($time / $seconds);
return "since $amount $unit".(($amount > 1) ? "s" : "");
}
}
我的编辑和回复都有效，但仍然不那么干净？试着想办法用另一种方式来做。
关于strtotime("yesterday")和strtotime("-2 days")呢？
试试这个：
function relativedate($timestamp, $limit = 1209600){
$diff = time() - $timestamp;
$time = ($diff < 1) ? 1 : $diff;
$value = '';
$times = array(
31536000 => "year",
2592000 => "month",
604800 => "week",
86400 => "day",
3600 => "hour",
60 => "minute",
1 => "second"
);
// Date limit as displayed full
if ($limit > 0 && $diff > $limit){
return "on ".date("d/m/Y - H:i:s", $timestamp);
}
// Recent days
if ($diff >= (24*60*60) && $diff < (48*60*60)) {
$value = "yesterday";
}
if ($diff >= (48*60*60) && $diff < (72*60*60)) {
$value = "the day before yesterday";
}
// Display x time ago
foreach ($times as $seconds => $text){
if ($time < $seconds) continue;
$amount = floor($time / $seconds);
$value = "since $amount $text".(($amount > 1 && $text != "mois") ? "s" : "");
break;
}
return $value;
}
echo relativedate(strtotime("-1 hour")).'<br />';
echo relativedate(strtotime("-23 hour")).'<br />';
echo relativedate(strtotime("-25 hour")).'<br />';
echo relativedate(strtotime("-49 hour")).'<br />';
echo relativedate(strtotime("-73 hour")).'<br />';
echo relativedate(strtotime("-1173 hour")).'<br />';
结果：
since 1 hour
since 23 hours
since 1 day
since 2 days
since 3 days
