// Skip all URL reserved characters plus dot, dash, underscore and tilde..

}else $diff=$now-$time;

if($diff<30) $output='همین حالا';
else if($diff>=30 && $diff<60) $output=$diff.' ثانیه '.$ago;
else if($diff>=60 && $diff<120) $output='کمتر از '.($diff/60).' دقیقه'.$ago;
else if($diff>=120 && $diff<3600){

if($ago=='پیش') $output='دیروز';
else $output='فردا';
$output.=' ساعت '.date('H:i:s',$time);
}else $output=date($format,$time);

return $output;
}



طرز استفاده هم به این صورت هست شما زمان رو به عنوان پارامتر می فرستید و تابع خروجی مناسب رو برمی گردونه
مثال
ورودی -> 1378461081 ====> خروجی -> دیروز ساعت 14:21:21
ورودی -> strtotime('-5 mins') ====> خروجی -> ۵ دقیقه پیش
ورودی -> strtotime('+5 mins') ====> خروجی -> ۵ دقیقه بعد

نحوه استفاده :




<img src="pim.php?file=image.jpg&x1=50&y1=50&x2=200&y2=100"/>


(با فرض اینکه کد فوق رو به اسم pim.php ذخیره کرده باشین).
کاربرد اصلی این اسکریپت برای وقتی هست که میخواین یک تصویر رو بصورت تکه تکه نشون بدین و با CSS تنظیم کنید تا کنار هم ظاهر بشه. دیگه نیازی نیست توی Photoshop یا سایر برنامه ها تصویر رو برش بدین و توی فایلهای جداگانه ذخیره کنید و در فضای هاست هم صرفه جویی میشه چون برای هر فایل جداگانه، هدرهای تصویر ذخیره میشن و این یعنی تکرار هدرها. کد فوق رو با کمی تغییر میتونید برای سایر انواع تصویر مثل png و... هم استفاده کنید.
موفق باشید.
