What is the significance of the error message "URL file-access is disabled in the server configuration" in PHP?

The error message "URL file-access is disabled in the server configuration" indicates that the PHP script is trying to access a file using a URL, which is not allowed due to security restrictions in the server configuration. To solve this issue, you can use the `file_get_contents()` function with a local file path instead of a URL.

$file_path = 'path/to/your/file.txt';
$file_contents = file_get_contents($file_path);

if ($file_contents === false) {
    echo 'Error reading file';
} else {
    echo $file_contents;
}
