$diff=50;//Set this to Maximum difference u can allow between numbers.
for($X=count($_AV);$X>=0;$X--)
{
if ($_AV[$X]== $arg)
{
$result=$X;
break;
}

else if(($_AV[$X]<$arg) AND ($arg-$_AV[$X] <=$diff)
{
$result=$X;
break;
}

else if(($_AV[$X]>$arg) AND ($_AV[$X]-$arg<=$diff)
{
$result=$X;
break;
}
else echo "No Matych found wth in this limit";

}

Hope this will work for u.
