Why does "var_dump" give me different data than "echo"?

Hi there,

I am putting some decimal data from a database into an array, in order to draw a graph. This works generally without problem. But from time to time, the graph doesn't display correctly.

Now, while echoing the data I get this:

43.2
45.2
49.6
56.2
65.1
70.2
50.5
38
36.6
14.3
15.2
6.6
4.1
5.4

Strange thing is that if I use a var_dump, I get this that is no more decimal data, but only integers:

array(1) { [0]=> array(14) { [0]=> string(2) "43" [1]=> string(2) "45" [2]=> string(2) "50" [3]=> string(2) "56" [4]=> string(2) "65" [5]=> string(2) "70" [6]=> string(2) "50" [7]=> string(2) "38" [8]=> string(2) "37" [9]=> string(2) "14" [10]=> string(2) "15" [11]=> string(1) "7" [12]=> string(1) "4" [13]=> string(1) "5" } }

I checked with other decimal data, and there the var_dump output is correct:

[0]=> string(10) "0.00004316"

that is, giving me the numbers behind the point too.

What can be the reason for this?

Thanks for any hints!

the reason depends on your data processing, as I don’t know that, I can’t really tell something.

PS. your data ain’t integers, they’re strings. generally, any data sent to the browser are strings.

Thanks a lot. Got me thinking (into a different direction before) and trying out some stuff, and finding the (formatting) error indeed before that step.
