Adding Values from an array larger than

Anon

I'm not sure why this is happening and I'm hoping someone will have an idea.

I have an array with numerical values in it, and i'm adding the values of the array together to get a total. For example $array[1] = 500, $array[2] = 11000, and $array[3] = 6000. If I add these values together array[1] + $array[2] + $array[3]. I'll get 517 rather than 17500. (500 + 11 + 6 instead of 500 +11000 + 6000).

If I echo each value in the array I get the correct values (500, 11000, 6000). It seems to be droping the 000's from the thousands range when I add the array together.

Does anyone know why it does this or how it
can be fixed?

Thanks

<?
$data=array(
500,
11000,
6000,
);
function sum($a,$b) {
return($a+$b);
}
print("sum : ".array_reduce($data,"sum"));
?>

fyi, output is sum : 17500

if this isn't what your after, paste offending code

17500 is the sum i'm after unfortunately i'm getting 517.

This is hard to explain, i'll explain because its too much code to post here.

Here's what i'm trying to do.

I've actually got several different arrays that i'm tring to add the values of together.

each array has 12 values 1 for each month.
$array1[1] = 100
$array1[2] = 123 all the way through
$array1[12] =200.

$array2[1] = 738
$array2[12] = 6000

$array3[1] = 500
$array3[12] = 11000 etc...

I've got about 15 differetn arrays like this.

when i try to add a value from each array together like: $array1[12] + $array2[12] + $array3[12] I get 217 (200 + 6 + 11) not 17200 (200 + 6000 + 11000).

IF i echo each array echo "$array2[12]"; It will return the correct value (6000) and not (6) so i know the value within the array is correct. For some reason it is not adding anything greater that 1000, but instead droping all of the digits, which make it over a thousand.

I know its hard to point out the problem exatcly with out posting my actual code, but It is a very long piece of code. I'm hoping someone h as run into this problem before or can recognize something i might be doing wrong.

I figured it out. I was using number_format on the values I was adding. It was seeing the , as a decimal point. Removed the formatting and it works fine now.
