PHP. Handle file_get_contents errors as Exception.

Below is the way to handle "file_get_contents" errors as ErrorExceptions:

set_error_handler(
    function ($errno, $errstr, $errfile, $errline) {
        throw new \ErrorException(
            $errstr, 0, $errno, $errfile, $errline
        );
    }
);

$contents = file_get_contents(
    $uri, false, $context
);

restore_error_handler();
