Re: testing for negative numbers

Is it possible that the value is actually " -2" (with the space)? Robert Samuel White wrote:

Well, I just tried your test script and that works just as it should, so I must be having some other issue. But that still doesn't explain why I can print out the results of $row["dir_id"] and it shows it being -2, yet my script (as printed in the last email) never makes it to the correct conditional statement.

Please provide a complete test script. Are you perhaps not realizing that array indices along with all variables in PHP are case sensitive? $row["ID"] and $row["id"] are not the same thing. The trivial test of your example:

       $myArray["id"] = -2;
       if ($myArray["id"] < 0) echo "Negative";
       else echo "Positive";

Prints "Negative" as expected. -Rasmus On Thu, 6 Feb 2003, Robert Samuel White wrote:

I realize this should be about the simplest thing in the world to do, but for this reason or that it's not working... I'm using PHP version 4.2.3 Whether I have a negative number in an array, for example: $myArray["ID"] = -2 Or the number comes from the database, for example: $row["id"] = -2 I cannot get this simple operation to work: if ($row["id"] < 0) Instead, positive or negative, it seems to think this expression is always true: if ($row["id"] > 0) It's like it takes the absolute value of the number (whether the number is 2 or -2, it thinks it is 2) I've tried many things, including type casting using (int) in front of the expression. Nothing has worked. Any ideas why in the world this is happening? Thanks. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
