如何将PHP中的unix时间戳转换为ISO8601时间戳？

Question

我想从MySQL中提取unix时间戳并将其转换为ISO8601时间戳。我需要它来将日期的格式设置为类似Facebook的格式（或“30分钟前的堆栈溢出”），而不是显示确切的日期和时间。有人处理过吗？

Answer 1

$timestamp = '1268932078'; 

$iso8601 = date('c', $timestamp); 

但也有内置的功能，以帮助你这个，如果你不希望推出自己的，例如：DateTime::diff。

Answer 2

的Facebook就像时间格式：

时差功能 输出在Facebook的 风格经过的时间：1天前，或4个月前。

http://www.php.net/manual/en/function.time.php#89415

function nicetime($date) 
{ 
    if(empty($date)) { 
     return "No date provided"; 
    } 
$periods = array("second","minute","hour","day","week","month","year","decade"); 
$lengths = array("60","60","24","7","4.35","12","10"); 
$now = time(); 
$unix_date = strtotime($date); 
    if(empty($unix_date)) {  
     return "Bad date"; 
    } 
    if($now > $unix_date) {  
     $difference  = $now - $unix_date; 
     $tense   = "ago"; 

    } else { 
     $difference  = $unix_date - $now; 
     $tense   = "from now"; 
    }  
    for($j = 0; $difference >= $lengths[$j] && $j < count($lengths)-1; $j++) { 
     $difference /= $lengths[$j]; 
    } 
    $difference = round($difference); 
    if($difference != 1) { 
     $periods[$j].= "s"; 
    } 
    return "$difference $periods[$j] {$tense}"; 
} 

// convert timestamp to date ISO8601 
$timestamp = date('c', '1268932078'); 
// convert to nice date 
echo nicetime($timestamp); //40 years ago
