The following code can be used to convert the number format into indian currency format (Indian rupees, INR) using PHP.
<?php
ob_start();
//Currency format conversion - Indian Rupee
$n = "1000000";
$len = strlen($n); //lenght of the no
$num = substr($n,$len-3,3); //get the last 3 digits
$n = $n/1000; //omit the last 3 digits already stored in $num
while($n > 0) //loop the process - further get digits 2 by 2
{
$len = strlen($n);
$num = substr($n,$len-2,2).",".$num;
$n = round($n/100);
}
echo "Rs.".$num;

No of days between two dates in php
We can find the no days between two dates using PHP....
There are 2 methods:
1) Split the date and subtract
$date1 = "2008-05-18";
$arr = explode('-',$date1); //split the date
$date2 = $arr[2]; //stores 18
$cur_date = date("d"); // current date
echo "Difference: ";
echo $cur_date-$date2;
2) Convert dates into timestamp, subtract and then convert as we want
$date1 = "2008-04-18";
$to_day = date("Y-m-d"); //current date
$day_diff = (strtotime($to_day)-strtotime($date1))/86400; //60*60*24=86400
echo $day_diff;
//change the divider(864000 to get ur corresponding difference
$hour_difference = (strtotime($to_day)-strtotime($date1))/3600; //60*60=3600
$week_diff = (strtotime($to_day)-strtotime($date1))/604800; //60*60*24*7=604800
