请帮我创建一个转换日期的功能，如
2010-10-04 17:45:50
进入更像
的东西10 October at 17:45
因此，如果不需要它们可以隐藏数年，并显示日期
today/yesterday at 17:45
这有点类似于Facebook显示过去日期的方式。

尝试使用此类： 我定义了一些常量转换为西班牙语，但你可以忽略它们或为其他函数制作验证语言！
您可以专注于这些功能： shortDateHuman（），longDateHuman（），shortTimeHuman（），longTimeHuman（）
要使用它，您可以执行：$datetest=new Date($language);然后使用
$datetest->longDateHuman();
此外，如果需要，您可以检查 setGMTOffset 功能。

所选答案与问题100％匹配。第二个做得更好（链接）。我还要指出Carbon，这是一个帮助约会的课程。您可能正在寻找的功能是：
echo Carbon::now()->subMinutes(2)->diffForHumans(); // '2 minutes ago'

我喜欢this function。它的输入是一个unix时间戳，这是自1970年1月1日以来的秒数。
public function FormatTime($timestamp)
{
// Get time difference and setup arrays
$difference = time() - $timestamp;
$periods = array("second", "minute", "hour", "day", "week", "month", "years");
$lengths = array("60","60","24","7","4.35","12");
// Past or present
if ($difference >= 0)
{
$ending = "ago";
}
else
{
$difference = -$difference;
$ending = "to go";
}
// Figure out difference by looping while less than array length
// and difference is larger than lengths.
$arr_len = count($lengths);
for($j = 0; $j < $arr_len && $difference >= $lengths[$j]; $j++)
{
$difference /= $lengths[$j];
}
// Round up
$difference = round($difference);
// Make plural if needed
if($difference != 1)
{
$periods[$j].= "s";
}
// Default format
$text = "$difference $periods[$j] $ending";
// over 24 hours
if($j > 2)
{
// future date over a day formate with year
if($ending == "to go")
{
if($j == 3 && $difference == 1)
{
$text = "Tomorrow at ". date("g:i a", $timestamp);
}
else
{
$text = date("F j, Y \a\\t g:i a", $timestamp);
}
return $text;
}
if($j == 3 && $difference == 1) // Yesterday
{
$text = "Yesterday at ". date("g:i a", $timestamp);
}
else if($j == 3) // Less than a week display -- Monday at 5:28pm
{
$text = date("l \a\\t g:i a", $timestamp);
}
else if($j < 6 && !($j == 5 && $difference == 12)) // Less than a year display -- June 25 at 5:23am
{
$text = date("F j \a\\t g:i a", $timestamp);
}
else // if over a year or the same month one year ago -- June 30, 2010 at 5:34pm
{
$text = date("F j, Y \a\\t g:i a", $timestamp);
}
}
return $text;

您可能还想看一下CakePHP助手。他们的TimeHelper做你想做的事。
