这篇文章主要介绍了php如何实现用已经过去多长时间的方式显示时间,具有一定借鉴价值,感兴趣的朋友可以参考下,希望大家阅读完这篇文章之后大有收获,下面让小编带着大家一起了解一下。

具体如下:
这里以一种可读性比较好的方式显示已经过去多长时间,比如:距离现在10秒,距离现在1天等等。
function time_is_older_than($t, $check_time){
$t = strtolower($t);
$time_type = substr(preg_replace('/[^a-z]/', '', $t), 0, 1);
$val = intval(preg_replace('/[^0-9]/', '', $t));
$ts = 0;
// (s)econds, (m)inutes, (d)ays, (y)ears
if ($time_type == 's'){ $ts = $val; }
else if ($time_type == 'm'){ $ts = $val * 60; }
else if ($time_type == 'h'){ $ts = $val * 60 * 60; }
else if ($time_type == 'd'){ $ts = $val * 60 * 60 * 24; }
else if ($time_type == 'y'){ $ts = $val * 60 * 60 * 24 * 365; }
else { die('Unknown time format given!'); }
if ($check_time < (time()-$ts)){ return true; }
return false;
}
//使用范例:
// timestamp to test:
// (could be from an database or something else)
$time = 1146722922;
// long if check:
if (time_is_older_than('30m', $time)){
print 'The given timestamp: ' . date('l dS \of F Y h:i:s A',$time);
print " - is older than 30 minutes
\n";
}
else {
print 'The given timestamp: ' . date('l dS \of F Y h:i:s A',$time);
print " - is NOT older than 30 minutes
\n";
}
// short checks:
if (time_is_older_than('10s', $time)){ print "Is older than 10 seconds
\n"; }
if (time_is_older_than('200m', $time)){ print "Is older than 200 minutes
\n"; }
if (time_is_older_than('2h', $time)){ print "Is older than 2 hours
\n"; }
if (time_is_older_than('4d', $time)){ print "Is older than 4 days
\n"; }
if (time_is_older_than('1y', $time)){ print "Is older than one year
\n"; }感谢你能够认真阅读完这篇文章,希望小编分享的“php如何实现用已经过去多长时间的方式显示时间”这篇文章对大家有帮助,同时也希望大家多多支持创新互联网站建设公司,,关注创新互联行业资讯频道,更多相关知识等着你来学习!
