Website Server was upgraded to PHP 5.4.30 and now doesn't work

[Learning]

I am a newbie to this forum and a real beginner on PHP

 

After the website went down after the server upgrade to 5.4.30, parts came back but in other places got 2 error messages.

 

1. Home page - Login by members

Fatal Error: call to undefined function session_is_registered() in member_auth_fns.php on line 28

 

2. Admin - Login by me

Parse error: syntax error, unexpected '$_SESSION' (T_VARIABLE), expecting '(' in contacts/user_auth_fns.php line 28

 

I appreciate that the old php was based on session_start (), session_register, session_is_registered, session_unregister, but these were all deprecated in 5.4.30.

 

So to put it bluntly, after trying to interpret the help manuals etc I found a backup I had taken before this and in respect of the Home page login and the admin login what I think was the previous relevant code was before the event

 

<?

function login ($member_name, $password)

// check member and password with db

// if yes, return true

//else return false

{

// connect to db

$conn = db_connect();

 

if (!$conn) return 0;

 $result = MySQL_query(select * from people

                                                     where username='$member_name'

                                                      and password = '$password' ");

if (!$result) return 0;

if (MySQL_num_rows($result)>0)

   return 1;

else

    return;

}

 

function check_auth_member

Some text here

global $auth_member;

if ( (session_is_registered("auth_member")) && (isset($auth_member)) )

return true;

else

return false

}

?>

 

 

Anyone who can give me the revised code for this it would be greatly appreciated

That code is in some serious need of being thrown out.

 

The session_is_registered function is deprecated.

The mysql_* extension is deprecated

Short tags have long been disabled by default.

 

And in general it's just poor code. Moving forward, you might want the code maintained.
