PHP - Dates Between A Certain Week

Hi All,

I need to subtract dates and display the number of days left.  I have a 'Start' date and an 'End' date in DATETIME format in the DB.  Not quite sure where to start.  A simply start - end doesn't work  .

Start = 2011-11-01-00:00:00
End = 2011-11-30-23:59:59

Since it is now 2011-11-27, my output should equal 3.  Any help is appreciated.

Hi guys,

I am trying to do a multidates events availability calender. The script below indicates todays date by highlighting an orange colour and also indicates the start and end date of the event highlighting grey colour on the two dates (The colour are link via css classes as shown).
Code: [Select]
//Today's date
$todaysDate = date("d/m/Y");
            $dateToCompare = $daystring . '/' . $monthstring . '/' . $year;
echo "<td align='center' ";
if($todaysDate == $dateToCompare){
echo "class='today'";
}else{
//Compare's the event dates
$sqlcount = "select event_start,event_end from b_calender where event_start ='".$dateToCompare."' AND event_end='".$dateToCompare."'";
$noOfEvent = mysql_num_rows(mysql_query($sqlcount));
if($noOfEvent >= 1){
echo "class='event'";
}
}
It works ok i.e. if start date = 01/01/2012 and end date = 04/01/2012 both date will be highlighted with grey colour. However I want it to also highlight grey on the dates between the 1st and 4th to show that then anydates between the 1st and 4th are not available and this is when I'm stuck.

Please guys I need help.

Thanks

Hello All,

I have read through this script a million times, and I can not for the life of me figure out how the script decides which day of the week to start on. Right now the week starts on Monday (which goes against every other calendar we use). I need to figure out how to make the week start on Sunday.

Here's the script:
<style type='text/css'>
.outofrange
{
background-color: #d9cdb3;
}
.currentday
{
background-color: #ccc;
}
</style>

<?PHP
$Year = preg_replace("/[^0-9]/","",$_GET['year']);
$Month = preg_replace("/[^0-9]/","",$_GET['month']);

if ($Year == "") { $Year = date("Y"); }
if ($Month==0)  { $Month=12; $Year--; }
if ($Month==13) { $Month=1;  $Year++; }

$myServer = "xxxxxx";
$myUser = "xxxxxx";
$myPass = "xxxxxx";

//connection to the database
$dbhandle = mssql_connect($myServer, $myUser, $myPass)
  or die("Couldn't connect to SQL Server on $myServer"); 

//select a database to work with
$selected = mssql_select_db($myDB, $dbhandle)

I have a PHP script that downloads a file from a remote server but in order to download the correct file it has to subtract 1 day of the week.  It used to work quite some time ago so I dont know what is going on now.  The section of the script goes like this....

$days = array("sun","mon","tue","wed","thu","fri","sat");
$today = date("w");
$yesterday = $days[$today - 1];

Then it joins the 3 letter version of the day of week with a file name to grab the correct file download.  $yesterday is not returning the correct value instead I am getting an error...

# ./update.php 
PHP Notice:  Undefined offset: -1 in /root/fcc/work/update.php on line 6
fetching l_am_.zip
ncftpget: server said: l_am_.zip: No such file or directory.
PHP Warning:  unlink(counts): No such file or directory in /root/fcc/work/update.php on line 23
data set empty nothing to process

So in the above error I can see that $yesterday is "Undefined offset" and because of that the file it tries to download is incorrect, it should have tried to download l_am_sat.zip and it left out the 3 letter date code.
