将时间戳转换为PHP中的时间戳，例如1天前、2天前。。。
我正在尝试转换格式为将时间戳转换为PHP中的时间戳，例如1天前、2天前。。。,php,timestamp,Php,Timestamp,我正在尝试转换格式为2009-09-12 20:57:19的时间戳，并使用PHP将其转换为类似3分钟前的格式 我找到了一个有用的脚本来实现这一点，但我认为它正在寻找一种不同的格式来用作时间变量。我想修改脚本以使用此格式： function _ago($tm,$rcs = 0) { $cur_tm = time(); $dif = $cur_tm-$tm; $pds = array('second','minute','hour','day','week','month'
2009-09-12 20:57:193分钟前的格式
我找到了一个有用的脚本来实现这一点，但我认为它正在寻找一种不同的格式来用作时间变量。我想修改脚本以使用此格式：
function _ago($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 $x;
}
我如何将时间戳转换成那种（unix？）格式？您必须获取每个时间戳，并将其转换成unix时间。例如时间戳，2009-09-12 20:57:19
（（（2008-1970）*365）+（8*30）+12）*24+20可以粗略估计自1970年1月1日以来的工作时间
取这个数字，乘以60，再加上57，得到分钟数
把它乘以60，再加上19
然而，这将非常粗略和不准确地转换它
有什么原因不能从正常的Unix时间开始吗？函数时间\u经过时间\u字符串（$ptime）
function time_elapsed_string($ptime)
{
$etime = time() - $ptime;
if ($etime < 1)
{
return '0 seconds';
}
$a = array( 365 * 24 * 60 * 60 => 'year',
30 * 24 * 60 * 60 => 'month',
24 * 60 * 60 => 'day',
60 * 60 => 'hour',
60 => 'minute',
1 => 'second'
);
$a_plural = array( 'year' => 'years',
'month' => 'months',
'day' => 'days',
'hour' => 'hours',
'minute' => 'minutes',
'second' => 'seconds'
);
foreach ($a as $secs => $str)
{
$d = $etime / $secs;
if ($d >= 1)
{
$r = round($d);
return $r . ' ' . ($r > 1 ? $a_plural[$str] : $str) . ' ago';
}
}
}
{
$etime=time（）-$ptime；
如果（$etime<1）
{
返回“0秒”；
}
$a=数组（365*24*60*60=>“年”，
30*24*60*60=>“月”，
24*60*60=>“天”，
60*60=>“小时”，
60=>“分钟”，
1=>“秒”
);
$a_复数=数组（'year'=>'years'，
“月”=>“月”，
“天”=>“天”，
“小时”=>“小时”，
“分钟”=>“分钟”，
“秒”=>“秒”
);
foreach（$a作为$secs=>$str）
{
$d=$etime/$secs；
如果（$d>=1）
{
$r=四舍五入（$d）；
返回$r.''（$r>1？$a_复数[$str]：$str）。'ago'；
}
}
}
我对原始函数做了一些修改（在我看来更有用，或者更符合逻辑）
//显示“X时间”之前，$rcs是精度深度
函数时间\u早（$tm，$rcs=0）{
$cur_tm=时间（）；
$dif=$cur_tm-$tm；
$pds=数组（'second'、'minute'、'hour'、'day'、'week'、'month'、'year'、'decade'）；
$lngh=阵列（1,6036008640060480026308031570560315705600）；
对于（$v=计数（$lngh）-1；（$v>=0）和（$no=$dif/$lngh[$v]）0）和（$v>=1））
$x.=''.$this->time\u ago（$\u tm，$rcs-1）；
返回$x；
}
使用示例：
echo time_exposed_string（'2013-05-01 00:22:35'）；
回音时间_经过_字符串（'@1367367755'）；#时间戳输入
回音时间字符串（'2013-05-01 00:22:35'，正确）；
输入可以是任意的
输出：
4个月前
4个月前
4个月2周3天1小时49分15秒前
功能：
函数时间\u经过\u字符串（$datetime，$full=false）{
$now=新日期时间；
$ago=新日期时间（$DateTime）；
$diff=$now->diff（$ago）；
$diff->w=地板（$diff->d/7）；
$diff->d-=$diff->w*7；
$string=数组(
‘y’=>‘年’，
'm'=>'month'，
“w”=>“周”，
'd'=>'day'，
“h”=>“小时”，
“i”=>“分钟”，
's'=>'秒'，
);
foreach（$k=>&$v的字符串）{
如果（$diff->$k）{
$v=$diff->$k.''.$v.（$diff->$k>1？'s'：''）；
}否则{
未设置（$string[$k]）；
}
}
如果（！$full）$string=array\u slice（$string，0，1）；
返回$string？内爆（'，'，$string）。'ago'：'just now'；
}
这实际上是我找到的一个更好的解决方案。使用jQuery，但是它工作得非常好。此外，它会自动刷新，与SO和Facebook的方式类似，因此您无需刷新页面即可查看更新
此插件将读取
标签中的datetime
attr并为您填写
e.g. "4 minutes ago" or "about 1 day ago
$time\u ago=''；
$time=time（）-$time；//从那一刻算起的时间
$tokens=数组(
31536000=>“年”，2592000=>“月”，604800=>“周”，86400=>“日”，3600=>“小时”，
60=>“分钟”，1=>“秒”）；
foreach（$unit=>$text形式的令牌）{
如果（$时间<$单位）继续；
$numberOfUnits=楼层（$time/$unit）；
$time\u ago='.$time\u ago.$numberOfUnits.'.$text.（$numberOfUnits>1）？'s'：''；
$time=$time%$unit；}echo$time\u ago；
只需将日期时间传递给此函数即可。它将以时间前的格式为您打印出来
date\u default\u timezone\u set（“您的时区”）；
函数转换（$datetime）{
$time=strottime（$datetime）；
$diff=time（）-$time；
$diff/=60；
$var1=楼层（$diff）；
$var=$var1=60）{
$diff/=60；
$var1=楼层（$diff）；
$var=$var1=24）{$diff/=24；$var1=floor（$diff）；$var=$var1=30.4375）{$diff/=30.4375；$var1=floor（$diff）；$var=$var1=12）{$diff/=12；$var1=floor（$diff）；$var=$var1以下是一个非常简单且非常有效的解决方案
