for loop problem?

Hello everyone, I have a pretty big list of codes that need to be put into a mysql db. The numbers range from 1000000 to 1223109. Here's the PHP I wrote to put these codes into a database: <? $connection = mysql_connect("blah","blah","blah"); $db = mysql_select_db("db_to_use", $connection); $value1 = "1000000"; $value2 = "1223109"; for($i="$value1"; $i<="$value2"; $i++) { mysql_query("INSERT INTO passcodes (passcode) VALUES ('P$i')"); if (mysql_error() != "") { print "<font face=Arial size=2>".mysql_error()."</font>"; exit; } } mysql_close($connection); ?> Everytime I run this from a browser, it just keeps looping. It should put about 223109 entries into the "passcodes" table. However, it just keeps looping. I'll end up with 400,000 or so entries before I stop it. I make sure I empty that table before I start running it again. Why is this happening? Thanks everyone, Tyler
