轉換x小時x分鐘前回到unix時間戳

Question

我正在尋找一種函數將「X小時前」和「X分鐘前」中提供的日期轉換回php中的時間戳，任何人都可以對此進行分解？

Answer 1

strtotime已經這樣做了：

$timestamp = strtotime("8 hours ago"); 

有關更多信息，請參閱relative time format specifications。

Answer 2

$hourago= "-1 hour"; 
$minago = "-2 minute"; 

$timestamp = strtotime($hourago.' '.$minago); 
echo $timestamp; 

或

$hourago= "-1"; 
$minago = "-2"; 

$timestamp = strtotime($hourago.' hour '.$minago.' minute'); 
echo $timestamp; 

Answer 3

我幫計算器上的人寫，做的這種反向，這裏是代碼的函數，我敢肯定，如果你解構和扭轉它，你將有你的答案：

<? 
$unix_time = 6734; 
echo howLongAgo($unix_time); 

function howLongAgo($time_difference){ 

// Swtich logic based on the time difference passed to this function, sets the english string and what number the difference needs to be divided by 
    switch($time_difference){ 
     case ($time_difference < 60): 
       $string = " second"; 
       break; 
     case ($time_difference >= 60 && $time_difference < 3600): 
       $string = " minute"; 
       $divider = 60; 
       break; 
     case ($time_difference >= 3600 && $time_difference < 86400): 
       $string = " hour"; 
       $divider = 3600; 
       break; 
     case ($time_difference >= 86400 && $time_difference < 2629743): 
       $string = " day"; 
       $divider = 86400; 
       break; 
     case ($time_difference >= 2629743 && $time_difference < 31556926): 
       $string = " month"; 
       $divider = 2629743; 
       break; 
     case ($time_difference >= 31556926): 
       $string = " year"; 
       $divider = 31556926; 
       break; 
    } 

// If a divider value is set during the switch, use it to get the actual difference 
if($divider){$diff = round($time_difference/$divider);}else{$diff = round($time_difference);} 
// If the difference does not equal 1, pluralize the final result EG: hours, minutes, seconds 
if($diff != 1){$pluralize="s";} 
// Concatenate all variables together and return them 
$final = $diff . $string . $pluralize . " ago"; 
return $final; 

} 
?>
