If you have
//Numbers.txt
1
2
3
4
5
6 <-New Line here
And you do print_r(file('numbers.txt')); You get =
Array
(
[0] => 1
[1] => 2
[2] => 3
[3] => 4
[4] => 5
[5] => 6
)
Again look at "6 <-New Line here". To the file function this is
going to be treated as 1 element. If it was 540A0A it would be
different. Why? Because that is what the file function does.
Please read again, "Note: Each line in the resulting array will
include the line ending, so you still need to use rtrim() if you do not
want the line ending present."
In a text editor it comes up as having a new line after 6 but the new
line character is on the same line as 6.
Now do you get this example?
//numbers.txt
1
2
3
5
6
7
Between 3 and 5 there are 2 new line characters in the middle of the
file. So that's why you get.
Array
(
[0] => 1
[1] => 2
[2] => 3
[3] =>
[4] => 5
[5] => 6
[6] => 7
)
Except if the last line was 0A0A it would be treated as one element in
the array.
