Question

知道为什么这个php函数会导致我的网站冻结吗？

 function makeAgo($timestamp){

  $difference = time() - $timestamp;
  $periods = array("sec", "min", "hr", "day", "week", "month", "year", "decade");
  $lengths = array("60","60","24","7","4.35","12","10");
  for($j = 0; $difference >= $lengths[$j]; $j++)
    $difference /= $lengths[$j];
    $difference = round($difference);
  if($difference != 1) $periods[$j].= "s";
    $text = "$difference $periods[$j] ago";
    return $text;
}

Answer 1

我想你需要改变这个：

  for($j = 0; $difference >= $lengths[$j]; $j++){
    $difference /= $lengths[$j];
    $difference = round($difference);
    if($difference != 1) $periods[$j].= "s";
      $text = "$difference $periods[$j] ago";
      return $text;
  }

因为如果你使用没有大括号的循环，只有第一个next语句在循环中连续执行，而不是任何其他语句。

如果您的时间戳差异小于零，则您的功能会冻结。
还有一件事你忘记提及十年或一年的长度。否则你的功能超级工作...... !!

尝试以下.. !!

 function makeAgo($timestamp){

$difference = time() - $timestamp;
if($difference < 0)
{
  $difference = 0;
}
$periods = array("sec", "min", "hr", "day", "week", "month", "year", "decade");
$lengths = array("60","60","24","7","4.35","12","10","10");
for($j = 0; $difference >= $lengths[$j]; $j++)
  $difference /= $lengths[$j];
  $difference = round($difference);
if($difference != 1) $periods[$j].= "s";
  $text = "$difference $periods[$j] ago";
  return $text;
}
