PHP returns the difference between two points in time and displays it in a very humanized way. Humanized design. Translation. Humanized service. English. Humanized city.

1. Custom function (super smart)

//Returns the difference between two time points and displays it in a very user-friendly way

//The function has two parameters. The first parameter refers to the start time, the default value is 1; the second parameter is the current (or end) time, the default is time()

<span style="font-size:18px;">function timespan($seconds = 1, $time = '')
	{

		if ( ! is_numeric($seconds))
		{
			$seconds = 1;
		}

		if ( ! is_numeric($time))
		{
			$time = time();
		}

		if ($time <= $seconds)
		{
			$seconds = 1;
		}
		else
		{
			$seconds = $time - $seconds;
		}

		$str = &#39;&#39;;
		$years = floor($seconds / 31536000);

		if ($years > 0)
		{
			$str .= $years.' 年, ';
		}

		$seconds -= $years * 31536000;
		$months = floor($seconds / 2628000);

		if ($years > 0 OR $months > 0)
		{
			if ($months > 0)
			{
				$str .= $months.' 月, ';
			}

			$seconds -= $months * 2628000;
		}

		$weeks = floor($seconds / 604800);

		if ($years > 0 OR $months > 0 OR $weeks > 0)
		{
			if ($weeks > 0)
			{
				$str .= $weeks.' 周, ';
			}

			$seconds -= $weeks * 604800;
		}

		$days = floor($seconds / 86400);

		if ($months > 0 OR $weeks > 0 OR $days > 0)
		{
			if ($days > 0)
			{
				$str .= $days.' 天, ';
			}

			$seconds -= $days * 86400;
		}

		$hours = floor($seconds / 3600);

		if ($days > 0 OR $hours > 0)
		{
			if ($hours > 0)
			{
				$str .= $hours.' 小时, ';
			}

			$seconds -= $hours * 3600;
		}

		$minutes = floor($seconds / 60);

		if ($days > 0 OR $hours > 0 OR $minutes > 0)
		{
			if ($minutes > 0)
			{
				$str .= $minutes.' 分钟, ';
			}

			$seconds -= $minutes * 60;
		}

		if ($str == '')
		{
			$str .= $seconds.' 秒, ';
		}

		return substr(trim($str), 0, -1);
    	}</span>

2. It is used in the php file as follows:

is used in the template of the tp framework as follows:

The above introduces the difference between the two time points returned by PHP, and displays it in a very user-friendly way, including human-friendly aspects. I hope it will be helpful to friends who are interested in PHP tutorials.
