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。
//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。
