PHP Quiz

Answer:

The file() reads a file into an array.

Each array element contains a line from the file, with newline still attached.

Syntax:

file(path,include_path,context)

Parameter	Description
path	Required. Specifies the file to read
include_path	Optional. Set this parameter to ‘1’ if you want to search for the file in the include_path (in php.ini) as well
context	Optional. Specifies the context of the file handle. Context is a set of options that can modify the behavior of a stream. Can be skipped by using NULL.

Tips and Notes

This function became binary-safe in PHP 4.3. (meaning that both binary data, like images, and character data can be written with this function).

Example

<?php
print_r(file("test.txt"));
?>

The output of the code above will be:

Array
(
[0] => Hello World. Testing testing!
[1] => Another day, another line.
[2] => If the array picks up this line,
[3] => then is it a pickup line?
)
