Question

I have dates array like this

$dates = array('2012-10-02','2012-10-03','2012-10-07', '2012-10-20');

Now if I have a current_date say

$current_date = '2010-10-11';

how would I find whats the closest PAST date to this. Which in this case would be 2012-10-07

thanks

Try like this

$dates = array('2012-10-02','2012-10-03','2012-10-07', '2012-10-20');

echo "<pre>";
print_r($dates);
$dateArray=array();

foreach($dates as $row)
$dateArray[] = date('Y-m-d', strtotime($row));

$current_date = date('Y-m-d', strtotime('2012-10-11'));
array_push($dateArray,$current_date);

sort($dateArray);

echo "<br />";
print_r($dateArray);
echo "</pre>";

echo "<br />";

$cd_index= array_search($current_date, $dateArray);

if($cd_index>0)
{
    $pastdate=$dateArray[$cd_index-1];
    echo "Pastarray-".$pastdate;
}
else
echo "No Past Date";

For Future Date:

if($cd_index<(count($dateArray)-1))
{
    $pastdate=$dateArray[$cd_index+1];
    echo "Pastarray-".$pastdate;
}
else
echo "No Future Date";
