What is the use of file in php?

The file function returns the contents of a file as an array, with one line per element in the array.

For instance, if I have a file that contains this:

Hello
This
Is
My
File

Then this is how the file function returns it:


<?php



$contents = file("myfile.txt");

print_r($contents);

?>

which prints

Array
(
[0] => Hello
[1] => This
[2] => Is
[3] => My
[4] => File
)
