How can PHP's built-in functions like ord() be utilized for efficient data encoding in PHP?

When encoding data in PHP, built-in functions like ord() can be utilized to efficiently convert characters into their ASCII values. This can be useful when working with binary data or when encoding data for transmission over networks. By using ord() to convert characters to ASCII values, you can create a more compact and efficient representation of the data. 

$data = "Hello, World!";
$encodedData = "";

for ($i = 0; $i < strlen($data); $i++) {
    $encodedData .= ord($data[$i]) . " ";
}

echo $encodedData;
