How To Open File And Load Contents Into A Variable

Hi,

in my PHP webpage I specify 3 files, like:

[CODE]
$first_file = $_POST[“one”];
$second_file = $_POST[“two”];
$third_file = $_POST[“three”];
[/CODE]

then I have a JS fuction, that in some points, needs to open each file and store the data of each file into a variable. My questions are 2:
First, how do I save all data of each text file into a JS variable?
Second, the part of the Js function which has these variables looks like this:

[CODE]
series:
[
{
name: ‘ONE’,
color: ‘blue’,
data:
[
HERE WE SHOULD PLACE ALL DATA FROM FILE 1
]
},

{
name: ‘TWO’,
color: ‘yellow’,
data:
[
HERE WE SHOULD PLACE ALL DATA FROM FILE 2
]
},

{
name: ‘THREE’,
color: ‘red’,
data:
[
HERE WE SHOULD PLACE ALL DATA FROM FILE 3
]
}
]
[/CODE]

Can you please help me, how I can put the data of each file into the correct place? I am new to JS and came across a helpful snipet of code, but I do not know how I can place my data inside the JS code so as to use them.

Thanks a lot!
