Numeric Comparing giving wrong answer

	echo "$_SESSION[totalcost] <br>";
	echo "$_SESSION[funds] <br>";
	IF ( $_SESSION[funds] < $_SESSION[totalcost] ) {
		echo "You do not have enough cash to upgrade <br>";
	} ELSE {
		echo "Upgrading... <br>";
	}	

 

Output:

 

75,000

622,500

You do not have enough cash to upgrade

 

I have no idea why. What reasons could it be?

It should work given that but maybe try something like this?

 

<?php
if (($_SESSION['funds'] - $_SESSION['totalcost']) < 0) {
   echo "Insufficient Funds";
}else {
   echo "Purchased";
}
?>

ok will try that.

 

however, i got it to work by removing the

 

	echo "$_SESSION[totalcost] <br>";
	echo "$_SESSION[funds] <br>";

 

statements, as a PHP Expert (you seem to be answering everyones questions with ease) why could this be?!

 

[edit]

your way worked. hm i deleted a few statements and it didnt work again, so used yours, and harruh!

Chances are it could be a notice conflict. Because you are essentially using constants to reference the index of the array. I would highly suggest you steer away from that and echo it out like so:

 

<?php
echo $_SESSION['totalcost'] ." <br>";
echo $_SESSION['funds'] . " <br>";
?>

 

The way above will overall be more efficient and correct. This way no notice is thrown for using an undefined constant. Essentially what happens right now, if you user funds without single quotes to try and grab an object at that index of the array the code first searchs to check to see if there is a constant called "funds" if not than it just assumes the word.

 

Anyhow maybe give that a test and see if that works.
