PHP转换HTML格式化日期
从Twitter搜索API Atom Feed返回的发布日期为2008-11-03T21:30:06Z,需要将其转换为“X秒/分钟/小时/天前”,以显示多久之前发布的Twitter消息。
认为这可以通过使用DATE_ATOM值的php date()函数来完成?
function time_since($your_timestamp) {
$unix_timestamp = strtotime($your_timestamp);
$seconds = time() - $unix_timestamp;
$minutes = 0;
$hours = 0;
$days = 0;
$weeks = 0;
$months = 0;
$years = 0;
if ( $seconds == 0 ) $seconds = 1;
if ( $seconds> 60 ) {
$minutes = $seconds/60;
} else {
return add_s($seconds,'second');
}
if ( $minutes >= 60 ) {
$hours = $minutes/60;
} else {
return add_s($minutes,'minute');
}
if ( $hours >= 24) {
$days = $hours/24;
} else {
return add_s($hours,'hour');
}
if ( $days >= 7 ) {
$weeks = $days/7;
} else {
return add_s($days,'day');
}
if ( $weeks >= 4 ) {
$months = $weeks/4;
} else {
return add_s($weeks,'week');
}
if ( $months>= 12 ) {
$years = $months/12;
return add_s($years,'year');
} else {
return add_s($months,'month');
}
}
function add_s($num,$word) {
$num = floor($num);
if ( $num == 1 ) {
return $num.' '.$word.' ago';
} else {
return $num.' '.$word.'s ago';
}
}
echo time_since('2008-11-03T21:30:06Z');
strtotime将处理该日期格式,给你一个unix时间戳。 然后,您可以按照如何计算相对时间的算法进行操作。 得到你的结果。
使用PHP 5.2中引入的DateTime功能很容易:
$posted = new DateTime('2008-11-03T21:30:06Z');
$now = new DateTime();
$interval = $posted->diff($now);
echo $interval->format('%a days'); // You can change this to be whatever format you like
