How can developers troubleshoot and resolve issues related to password hashing algorithms, such as switching from MD5 to SHA1 in PHP scripts?

To troubleshoot and resolve issues related to switching from MD5 to SHA1 in PHP scripts, developers can update the hashing algorithm used in their password handling functions. This involves replacing the calls to the MD5 function with the SHA1 function. Additionally, developers should ensure that the stored passwords are re-hashed using the new algorithm to maintain security. 

// Update the password hashing function from MD5 to SHA1
function hash_password($password) {
    return sha1($password);
}

// Example usage
$old_password = "password123";
$new_password = hash_password($old_password);
echo $new_password;
