I'm trying the following, 

I have different files (8 files) that stores values like this:

```
1      2      3      4      5      6
7      8      9      10     11     12
....................

```

I would like to read 8 files at the same time and create an array that will store the first value of each file, another array with the second element, and so on.

For example, if first element of file1 is `1`, in file2 `8`, ..., in file8 `23`; the resulting array in this iteration would be:

```
first_array = [1, 8, ....., 23]

```

I was making some tests on reading files in PHP like this:

```
$myfile = fopen("textoPrueba.txt", "r", 
"/home/berni/Documentos/Vesta1");
// Output one character until end-of-file
while(!feof($myfile))
{
   echo fgetc($myfile);
}
fclose($myfile);

```

This code just show me the elements of a file, but I would like to take specific elements in an iteration.

Someone can give me a hint? Thanks in advance

(NOTE: files have more than a million of elements)
