Way is this doing this Starting with 1000 all I what to do is increse
this number by one the first time I run it it adds 1 to the number 10001
second time it 10001002
Shouldn't it just add 1 to the number 1000,1001,1002,1003
<?
//$num ="1000";
$fp2=fopen ("number","r+")or die("unable to open file (number)");
$data = fgets($fp2, 1000);
$data1 = $data + "1";
fwrite($fp2,$data1);
echo $data1;
?>

Richard
