How can PHP be used to manually load a file from a directory?
To manually load a file from a directory using PHP, you can use the `file_get_contents()` function. This function reads the entire contents of a file into a string. You need to provide the path to the file you want to load as an argument to this function.
$file_path = 'path/to/your/file.txt';
$file_content = file_get_contents($file_path);
echo $file_content;
