php实现用已经过去多长时间的方式显示时间

前端之家收集整理的这篇文章主要介绍了php实现用已经过去多长时间的方式显示时间前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

本文实例讲述了PHP用已经过去多长时间的方式显示时间的方法分享给大家供大家参考。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。

PHP;"> function time_is_older_than($t,$check_time){ $t = strtolower($t); $time_type = substr(preg_replace('/[^a-z]/','',$t),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"; }

希望本文所述对大家的PHP程序设计有所帮助。
