php中时间轴开发(刚刚、5分钟前、昨天10:23等)_php技巧

function tranTime($time) { 
$rtime = date("m-d H:i",$time); 
$htime = date("H:i",$time); 
$time = time() - $time; 
if ($time < 60) { 
$str = '刚刚'; 
} 
elseif ($time < 60 * 60) { 
$min = floor($time/60); 
$str = $min.'分钟前'; 
} 
elseif ($time < 60 * 60 * 24) { 
$h = floor($time/(60*60)); 
$str = $h.'小时前 '.$htime; 
} 
elseif ($time < 60 * 60 * 24 * 3) { 
$d = floor($time/(60*60*24)); 
if($d==1) 
$str = '昨天 '.$rtime; 
else 
$str = '前天 '.$rtime; 
} 
else { 
$str = $rtime; 
} 
return $str; 
} 
 
函数tranTime()中的参数$time必须为Unix时间戳，如果不是请先用strtotime()将其转换成Unix时间戳。上面的代码一看就明白了，不用再多述。 
调用函数，直接

$times="1286861696 "; 
echo tranTime($times);
