The file() reads a file into an array.
Each array element contains a line from the file, with newline still attached.
|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).
The output of the code above will be:
 => Hello World. Testing testing!
 => Another day, another line.
 => If the array picks up this line,
 => then is it a pickup line?
