Yeah, I thought so seeing as I had done it like that previously, turns out it was something else that was causing the problem ":D Thanks anyhow ":D -----Original Message----- From: Hutchins, Richard [mailto:Richard.Hutchins@xxxxxxxxxxxxxx] Sent: Thursday, September 30, 2004 5:43 PM To: 'Darryl'; php-db@xxxxxxxxxxxxx Subject: RE: String handling If you use the value from a text box in a mathematical equation or comparison, PHP will automatically attempt to handle it as an integer or some other numeric type (e.g., float). So if you did something like: if($_POST["myvar"] < 10000){ ... } PHP would handle $_POST["myvar"] as an integer automatically since it's being compared to another integer. Chapter 7: Type Juggling in the PHP manual sums this all up nicely. If you want to explicitly cast your variable as an integer, you can do either: settype($_POST["myvar"], "integer"); OR $intval = (int) $_POST["myvar"]; Either way, you're still going to want to do some data validation to make sure that the value in your text box is a number and not a text string before you convert it because you may get unexpected results if you try to convert a string to an integer depending on the contents of the string. The String Conversion section in the Strings chapter of the PHP documentation provides examples of how strings get converted to integers (and other types) by PHP. I am certainly no expert on type casting and have been stung by problems like this in the past. But check out the parts of the PHP documentation I cited and you should be able to figure out what needs to be done.
