How can PHP developers prevent unauthorized users from requesting a new password for another user's account?

To prevent unauthorized users from requesting a new password for another user's account, PHP developers can implement a token-based system where a unique token is generated and sent to the user's email for password reset. This token should be securely stored in the database and checked against the user's email address to ensure that only the rightful owner can reset their password. 

// Generate a unique token for password reset
$token = bin2hex(random_bytes(16));

// Store the token in the database along with the user's email address
// Make sure to hash the token before storing it for added security

// Send the token to the user's email address for password reset
// Include a link with the token as a query parameter in the email

// When the user clicks on the link, validate the token against the user's email address
// If the token is valid, allow the user to reset their password
