How can the functionality of the ASCII encoder program be improved by incorporating chr() and modulo operators in PHP?

The functionality of the ASCII encoder program can be improved by incorporating the chr() function to convert ASCII values to characters and modulo operators to handle values greater than 127. By using chr() and modulo operators, we can ensure that the encoded output includes all ASCII characters, not just those within the range of 0-127. 

function ascii_encoder($input) {
    $output = '';
    
    for ($i = 0; $i < strlen($input); $i++) {
        $ascii_value = ord($input[$i]);
        $encoded_value = $ascii_value % 128;
        $output .= chr($encoded_value);
    }
    
    return $output;
}

// Example usage
$input = "Hello, World!";
echo ascii_encoder($input);
