What are the advantages of accessing files through the local filesystem in PHP instead of using URL/http?

When accessing files through the local filesystem in PHP instead of using URL/http, you can have faster access to the files since you are not making a network request. Additionally, you have more control over the file operations and can easily manipulate files on the server without worrying about permissions or network issues.

$file_path = '/path/to/file.txt';

// Read file contents
$file_contents = file_get_contents($file_path);

// Write to file
file_put_contents($file_path, 'Hello, World!');

// Check if file exists
if (file_exists($file_path)) {
    echo 'File exists!';
}
