Check Date Between Two Dates in PHP

function dateBetween( $checkDate )
{
$firstDate1 = strtotime( "15-Jan-2008" );
$firstDate2 = strtotime( "15-Mar-2008" );
$secondDate1 = strtotime( "16-Mar-2008" );
$secondDate2 = strtotime( "15-Jun-2008" );

$checkDate = strtotime( $checkDate );

if( $checkDate > $firstDate1 && $checkDate < $firstDate2 )
{
return "2000";
}
elseif( $checkDate > $secondDate1 && $checkDate < $secondDate2 )
{
return "4000";
}

return "0";
}

echo dateBetween( "25-Sep-2008" );

?>

How to calculate the date difference between 2 dates using php

$date1 = "2006-03-25";
$date2 = "2009-11-10";

$diff = abs(strtotime($date2) - strtotime($date1));

$years = floor($diff / (365*60*60*24));
$months = floor(($diff - $years * 365*60*60*24) / (30*60*60*24));
$days = floor(($diff - $years * 365*60*60*24 - $months*30*60*60*24)/ (60*60*24));

printf("%d years, %d months, %d days\n", $years, $months, $days);

How can store session in data base

Step1: Create A Table:
CREATE TABLE `sessions` (
`session_key` char(32) NOT NULL,
`session_expire` int(11) unsigned NOT NULL,
`session_value` text NOT NULL,
PRIMARY KEY (`session_key`)
)

Step2 : Create A connection file
configure.php
$HOST = "localhost";
$DBNAME="sessions";
$USER = "nanhe";
$PASS = "chapra";
$HANDLER = "";
$LIFETIME = get_cfg_var("session.gc_maxlifetime");
?>

Step3 : Create handler
handler.php
include("configure.php");
function sessionOpen($save_path, $session_name){

global $HOST, $DBNAME, $USER, $PASS, $HANDLER;

if (!$HANDLER = mysql_pconnect($HOST, $USER, $PASS)) {
echo("

Can't connect to $HOST as $USER");
echo("

MySQL Error: ". mysql_error());
die;
}

if (! mysql_select_db($DBNAME, $HANDLER)) {
echo("

We were unable to select database $DBNAME");
die;
}

return true;
}

function sessionClose()
{

return true;
}

function sessionRead($session_key)
{
global $session;
$session_key = addslashes($session_key);

$session_session_value =
mysql_query("SELECT session_value
FROM sessions WHERE session_key = '$session_key'")
or die(mysql_error());

if (mysql_numrows($session_session_value) == 1) {
return mysql_result($session_session_value, 0);
} else {
return false;
}
}

function sessionWrite($session_key, $val)
{
global $session;
echo "The value=".$val;
$session_key = addslashes($session_key);
$val = addslashes($val);
$session = mysql_result(mysql_query("SELECT COUNT(*) FROM sessions
WHERE session_key = '$session_key'"), 0);

if ($session == 0) {
$return =
mysql_query("INSERT INTO sessions
(session_key, session_expire, session_value)
VALUES ('$session_key',
UNIX_TIMESTAMP(NOW()), '$val')")
or die(mysql_error());
} else {
$return = mysql_query("UPDATE sessions
SET session_value = '$val',
session_expire = UNIX_TIMESTAMP(NOW())
WHERE session_key = '$session_key'")
or die(mysql_error());

if (mysql_affected_rows() < 0) {
echo("We were unable to update session
session_value for session $session_key");
}
}
return $return;
}


function sessionDestroy($session_key)
{
global $session;
$session_key = addslashes($session_key);

$return = mysql_query("DELETE FROM sessions
WHERE session_key = '$session_key'")
or die(mysql_error());
return $return;
}

function sessionGc($maxlifetime)
{
global $session;
$expirationTime = time() - $maxlifetime;

$return = mysql_query("DELETE FROM sessions WHERE session_expire <
$expirationTime") or die("sessionGc Function".mysql_error());
return $return;
}

session_set_save_handler("sessionOpen", "sessionClose", "sessionRead", "sessionWrite", "sessionDestroy", "sessionGc");
