我正在尝试转换格式为2009-09-12 20:57:19的时间戳，并将其转换为3分钟前用PHP。
我找到了一个有用的脚本来做这件事，但我认为它正在寻找一种不同的格式来用作时间变量。我想修改的脚本与此格式的工作是:
function _ago($tm,$rcs = 0) {
$cur_tm = time();
$dif = $cur_tm-$tm;
$pds = array('second','minute','hour','day','week','month','year','decade');
$lngh = array(1,60,3600,86400,604800,2630880,31570560,315705600);
for($v = sizeof($lngh)-1; ($v >= 0)&&(($no = $dif/$lngh[$v])<=1); $v--); if($v < 0) $v = 0; $_tm = $cur_tm-($dif%$lngh[$v]);
$no = floor($no);
if($no <> 1)
$pds[$v] .='s';
$x = sprintf("%d %s ",$no,$pds[$v]);
if(($rcs == 1)&&($v >= 1)&&(($cur_tm-$_tm) > 0))
$x .= time_ago($_tm);
return $x;
}
我认为在前几行脚本试图做的事情看起来像这样(不同的日期格式数学):
$dif = 1252809479 - 2009-09-12 20:57:19;
如何将我的时间戳转换成那种(unix?)格式?
举个例子:
echo time_elapsed_string('2013-05-01 00:22:35');
echo time_elapsed_string('@1367367755'); # timestamp input
echo time_elapsed_string('2013-05-01 00:22:35', true);
输入可以是任何受支持的日期和时间格式。
输出:
4 months ago
4 months ago
4 months, 2 weeks, 3 days, 1 hour, 49 minutes, 15 seconds ago
功能:
function time_elapsed_string($datetime, $full = false) {
$now = new DateTime;
$ago = new DateTime($datetime);
$diff = $now->diff($ago);
$diff->w = floor($diff->d / 7);
$diff->d -= $diff->w * 7;
$string = array(
'y' => 'year',
'm' => 'month',
'w' => 'week',
'd' => 'day',
'h' => 'hour',
'i' => 'minute',
's' => 'second',
);
foreach ($string as $k => &$v) {
if ($diff->$k) {
$v = $diff->$k . ' ' . $v . ($diff->$k > 1 ? 's' : '');
} else {
unset($string[$k]);
}
}
if (!$full) $string = array_slice($string, 0, 1);
return $string ? implode(', ', $string) . ' ago' : 'just now';
}
这是我的解决方案，请检查并根据您的要求修改
function getHowLongAgo($date, $display = array('Year', 'Month', 'Day', 'Hour', 'Minute', 'Second'), $ago = '') {
date_default_timezone_set('Australia/Sydney');
$timestamp = strtotime($date);
$timestamp = (int) $timestamp;
$current_time = time();
$diff = $current_time - $timestamp;
//intervals in seconds
$intervals = array(
'year' => 31556926, 'month' => 2629744, 'week' => 604800, 'day' => 86400, 'hour' => 3600, 'minute' => 60
);
//now we just find the difference
if ($diff == 0) {
return ' Just now ';
}
if ($diff < 60) {
return $diff == 1 ? $diff . ' second ago ' : $diff . ' seconds ago ';
}
if ($diff >= 60 && $diff < $intervals['hour']) {
$diff = floor($diff / $intervals['minute']);
return $diff == 1 ? $diff . ' minute ago ' : $diff . ' minutes ago ';
}
if ($diff >= $intervals['hour'] && $diff < $intervals['day']) {
$diff = floor($diff / $intervals['hour']);
return $diff == 1 ? $diff . ' hour ago ' : $diff . ' hours ago ';
}
if ($diff >= $intervals['day'] && $diff < $intervals['week']) {
$diff = floor($diff / $intervals['day']);
return $diff == 1 ? $diff . ' day ago ' : $diff . ' days ago ';
}
if ($diff >= $intervals['week'] && $diff < $intervals['month']) {
$diff = floor($diff / $intervals['week']);
return $diff == 1 ? $diff . ' week ago ' : $diff . ' weeks ago ';
}
if ($diff >= $intervals['month'] && $diff < $intervals['year']) {
$diff = floor($diff / $intervals['month']);
return $diff == 1 ? $diff . ' month ago ' : $diff . ' months ago ';
}
if ($diff >= $intervals['year']) {
$diff = floor($diff / $intervals['year']);
return $diff == 1 ? $diff . ' year ago ' : $diff . ' years ago ';
}
}
谢谢
