php is one of the few languages that makes this real easy.

$futuredate = strtotime($originaldate . " +2 weeks")

oh and I guess if you want it back in the same string format that you had the original date in, as opposed to a numeric php date type:

$futuredate = date("d-m-Y", strtotime($originaldate . " +2 weeks"));

Finally, if you want to calculate what the date is two weeks from NOW:

$futuredate = strtotime(date("d-m-Y") . " +2 weeks");

For each date in your list, do
if( strtotime($originaldate) == $futuredate )  {
    echo "that's the one.";
}

I did this
<?
$sqlmain = mysql_query("select * from table");
$futuredate = strtotime(date("d-m-Y") . " +2 weeks");
$row = mysql_fetch_array($sqlmain);
$numrows=mysql_num_rows($sqlmain);
?>
<table width="90%" border="2">
 <tr>
 <td>Start Date</td>
    <td>End Date</td>
    <td>Future Date </td>
    <td>Matched</td>
   
    </tr>
<?
$i = 0;
  while($i<$numrows){

$startdate = mysql_result($sqlmain, $i, "bstart_district");
$enddate = mysql_result($sqlmain, $i, "bend_distroct");

 
?>  
  <tr>
    <td><?php echo $startdate; ?></td>
    <td><?php echo $enddate; ?></td>
    <td><?php echo $futuredate; ?></td>
    <td>
   <? if( strtotime($startdate) == $futuredate )  {
    echo "that's the one.";
}
 ?>  

It puts the date in some other format like this

Start Date  End Date          Future Date          Matched
9-25-2007  9-26-2007     1215666000  
9-12-2007  9-12-2007     1215666000  
9-25-2007  9-26-2007     1215666000


thanks

Yes, the format is an internal PHP date format - it represents the number of seconds since jan 1900 or something like that. I don't quite remember.

It is best to deal with this format as much as possible. When extracting data from MySql, the date will come as a string. You use strtotime() to convert the string to a PHP date number type which can be used in PHP's wide range of date functions. Then you use date() to reconvert it back to a string for display purposes.

$formatteddate = date("d-m-Y", $futuredate);
