Returns the file in an array. Each element of the array corresponds to a
line in the file, with the newline still attached. Upon failure,
file() returns FALSE.
Note:
Each line in the resulting array will include the line ending, unless
FILE_IGNORE_NEW_LINESis used, so you still need to use rtrim() if you do not want the line ending present.
