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。

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<br/>/n";}else {  print 'The given timestamp: ' . date('l dS /of F Y h:i:s A',$time);  print " - is NOT older than 30 minutes<br/>/n";}// short checks:if (time_is_older_than('10s', $time)){ print "Is older than 10 seconds<br/>/n"; }if (time_is_older_than('200m', $time)){ print "Is older than 200 minutes<br/>/n"; }if (time_is_older_than('2h', $time)){ print "Is older than 2 hours<br/>/n"; }if (time_is_older_than('4d', $time)){ print "Is older than 4 days<br/>/n"; }if (time_is_older_than('1y', $time)){ print "Is older than one year<br/>/n"; }

希望本文所述对大家的php程序设计有所帮助。
