What is the correct method to access the content of a .txt file in PHP?

To access the content of a .txt file in PHP, you can use the `file_get_contents()` function. This function reads the entire contents of a file into a string. You simply need to provide the file path as the argument to `file_get_contents()` to retrieve the content of the file.

$file_path = 'example.txt';
$file_content = file_get_contents($file_path);

echo $file_content;
