เต้มาถามเลย สงสัยเหมือนกัน ไปหาๆ มาได้อันนี้
This is an easily extendable and pretty way to output human-readable date differences such as "1 day 2 hours ago", "6 months ago", "3 years 7 months 14 days 1 hour 4 minutes 16 seconds" etc etc.
Change "$levels = 2;" to whatever you want. A value of 1 will limit to only one number in the result ("3 days ago"). A value of 3 would result in up to three ("3 days 1 hour 2 minutes ago")
<?php
function compare_dates($date1, $date2 = time())
{
$blocks = array(
array('name'=>'year','amount' => 60*60*24*365 ),
array('name'=>'month','amount' => 60*60*24*31 ),
array('name'=>'week','amount' => 60*60*24*7 ),
array('name'=>'day','amount' => 60*60*24 ),
array('name'=>'hour','amount' => 60*60 ),
array('name'=>'minute','amount' => 60 ),
array('name'=>'second','amount' => 1 )
);
$diff = abs($date1-$date2);
$levels = 2;
$current_level = 1;
$result = array();
foreach($blocks as $block)
{
if ($current_level > $levels) {break;}
if ($diff/$block['amount'] >= 1)
{
$amount = floor($diff/$block['amount']);
if ($amount>1) {$plural='s';} else {$plural='';}
$result[] = $amount.' '.$block['name'].$plural;
$diff -= $amount*$block['amount'];
}
}
return implode(' ',$result).' ago';
}
?>
วิธีใช้ก็ สั่ง echo ฟังก์ชัน + ตัวแปร ข้างล่างนี้ (เลือกมาตัวนึง
It can be used in the following ways:
echo compare_dates($start_date,$end_date);
echo compare_dates($end_date,$start_date);
echo compare_dates($start_date); //end date will be assumed as time();
มีอีกหลายอัน
