It is also possible to read and output the contents of an entire file with the ''readfile()'' function. This function reads the entire contents of a file and outputs that content. Assuming you don't need to do anything but output the contents of a file then ''readfile()'' is an easy solution because it does all the work for you. You do not need to open the file, read the data, close the file and display the data. All you need to do is call ''readfile()'' passing in the file path as an argument and it does the rest.
