'Little' date/time function

[scrupul0us]

im pretty sure this can be collapsed:

function timewhen($timestamp, $tence='ago')
{
	if ($tence == 'ago')
	{
	$tence = 'Ago';
	$difference = time() - $timestamp;
	}
	else
	{
	$tence = 'Left';
	$difference = $timestamp - time();
	}

if($difference < 60)
($difference == '1') ? $string = $difference." Second ".$tence : $string = $difference." Seconds ".$tence;
else
{
$difference = round($difference / 60);
if($difference < 60)
($difference == '1') ? $string = $difference." Minute ".$tence : $string = $difference." Minutes ".$tence;
else
{
$difference = round($difference / 60);
if($difference < 24)
($difference == '1') ? $string = $difference." Hour ".$tence : $string = $difference." Hours ".$tence;
else
{
$difference = round($difference / 24);
if($difference < 7)
($difference == '1') ? $string = $difference." Day ".$tence : $string = $difference." Days ".$tence;
else
{
$difference = round($difference / 7);
if($difference < 4)
($difference == '1') ? $string = $difference." Week ".$tence : $string = $difference." Weeks ".$tence;
else
{
$difference = round($difference / 4);
($difference == '1') ? $string = $difference." Month ".$tence : $string = $difference." Months ".$tence;
}			
}
}
}
}
return $string;	
}

what do you think

[scrupul0us]

any now that im looking at it... with the setup i have now, if the difference is 1, then for the first check lets say ill either get:

1 Day Ago or 1 Day Left... what I'd like is Yesterday or Tomorrow

that means breaking out all the conditionals into nested IFs and it becomes HUGE

[scrupul0us]

function timewhen($timestamp, $tence='ago')
{
	if ($tence == 'ago')
	{
	$tence = 'Ago';
	$difference = time() - $timestamp;
	}
	else
	{
	$tence = 'Left';
	$difference = $timestamp - time();
	}

if($difference < 60)
($difference == '1') ? $string = $difference." Second ".$tence : $string = $difference." Seconds ".$tence;
else
{
$difference = round($difference / 60);
if($difference < 60)
($difference == '1') ? $string = $difference." Minute ".$tence : $string = $difference." Minutes ".$tence;
else
{
$difference = round($difference / 60);
if($difference < 24)
($difference == '1') ? $string = $difference." Hour ".$tence : $string = $difference." Hours ".$tence;
else
{
$difference = round($difference / 24);
if($difference < 7)
{
if ($difference == '1' && $tence == 'Ago') $string = "Yesterday";
if ($difference == '1' && $tence == 'Left') $string = "Tomorrow";
if ($difference != '1') $string = $difference." Days ".$tence;
}
else
{
$difference = round($difference / 7);
if($difference < 4)
{
if ($difference == '1' && $tence == 'Ago') $string = "Last Week";
if ($difference == '1' && $tence == 'Left') $string = "Next Week";
if ($difference != '1') $string = $difference." Weeks ".$tence;
}
else
{
$difference = round($difference / 4);
{
if ($difference == '1' && $tence == 'Ago') $string = "Last Month";
if ($difference == '1' && $tence == 'Left') $string = "Next Month";
if ($difference != '1') $string = $difference." Months ".$tence;
}
}			
}
}
}
}
return $string;	
}

actually wasnt bad, but its still seems bulky

One improvement can be made if you use a boolean to store boolean information - instead of using a string.

function timewhen($timestamp, $past = true)
{
	$seconds = $timestamp -time();
	if ($past)
		$seconds = - $seconds;
	$tense = $past ? "Ago" : "Left";

$minutes = floor($seconds / 60);

if (!$minutes)
{
	return $seconds. ($seconds == 1 ? " Second" : " Seconds")." ".$tense;
}

$hours = floor($seconds / 3600);
if (!$hours)
{
	return $minutes. ($minutes == 1 ? " Minute" : " Minutes")." ".$tense;
}

$days = floor($seconds / (3600 * 24)); // Ignore daylight saving
if (!$days)
{
	return $hours. ($hours == 1 ? " Hour" : " Hours")." ".$tense;
}

$weeks = floor($seconds / (3600 * 24 * 7));
if (!$weeks)
{
	if ($days == 1)
	{
		$string = $past ? "Yesterday" : "Tomorrow";
	}
	else
	{
		$string = $days." Days ".$tense;
	}
	return $string;
}

$months = floor($seconds / (3600 * 24 * 7 * 4)); // It's all only approximate anyway
if (!$months)
{
	if ($weeks == 1)
	{
		$string = $past ? "Last Week" : "Next Week";
	}
	else
	{
		$string = $weeks." Weeks ".$tense;
	}
	return $string;
}
if ($months == 1)
{
	$string = $past ? "Last Month" : "Next Month";
}
else
{
	$string = $weeks." Months ".$tense;
}
return $string;
}
