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 \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。
