Answer:
A)
The file() reads a file into an array.
Each array element contains a line from the file, with newline still attached.
Syntax:
|
1 |
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
123
<?phpprint_r(file("test.txt"));?>
The output of the code above will be:
1234567
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?)
