What is the difference between file () and fread()?

Question

I suppose the open a file using fopen([name],r) and fread to access its contents works as well.
so what is the difference to file([name])?
And why these two ways?

Answer 1

file reads the whole of the file into an array. fread will read up to a set byte length. with file, each line is an array key; knowing which lines you need, you can print those lines. Or, you can loopthe pointer and print the whole of the document.
