Create a secure token for your PHP app in minutes! Learn how with this step-by-step example.
Creating a PHP Token
A token is a unique identifier generated by the server that is used to identify and verify the user’s identity. In this tutorial, we will learn how to generate a secure random token in PHP.
First, we will use the random_bytes
function to generate a random string of bytes. This function takes a single argument, which is the length of the random string in bytes. We will use 32 bytes to generate a 256-bit token.
$token = random_bytes(32);
The $token
variable now holds a random string of bytes. We now need to convert this string of bytes into a string of hexadecimal characters.
$hex = bin2hex($token);
The $hex
variable now holds the hexadecimal representation of the random bytes. We can now use the hash
function to hash the hexadecimal string.
$hash = hash('sha256', $hex);
The $hash
variable now holds the SHA256 hash of the hexadecimal string. We can now convert the hexadecimal string into a URL-safe string using the base64_encode
function.
$token = base64_encode($hash);
The $token
variable now holds a URL-safe string that can be used as a token. We can now store this token in a database or pass it to the client.
We have now created a secure random token in PHP. This token can be used to identify and verify the user’s identity. It is important to note that the token should be stored securely and not be disclosed to anyone else.
