Parse Errors

Last Modified: 2010-05-18
I bought a book from Wiley Publishing which included a ton of PHP / MySQL Examples.

None of the code seems to work on a Windows or Linux box.

In the following code lines 9, 10, 15, 18 and 44 all state that I have a Parse error. The other consistent part is this;
session_user()-> in all 5 lines

Any Help here would be Great and Thanks!

print start_page('Project Management Example');

$query = 'select p.project_id, p.project, p.due_dt
            , if(p.owner_id=?,1,0) as is_owner
      from projects p
$bind = array(session_user()->user_id);
if (!session_user()->is_admin())
      $query .= ' , project_user_map m
            where p.project_id = m.project_id and m.user_id = ?
      $bind[] = session_user()->user_id;
$query .= ' order by is_owner desc, p.due_dt ';
$rows = session_user()->dbh()->getAll($query, $bind);

$links = array();
$done_id = Status::status_id('done');
$cancelled_id = Status::status_id('cancelled');
$slipped_id = Status::status_id('slipped');
foreach ($rows as $row)
      extract($row, EXTR_OVERWRITE|EXTR_PREFIX_ALL, 'p');
      $tlinks = array();
      $tlinks[] = anchor_tag(
            , 'Calendar'
      $tlinks[] = anchor_tag(
            , 'Task List'
      $query = 'select t.*, u.user as owner
            from tasks t left join users u on t.owner_id = u.user_id
            where t.project_id = ?
                  and t.status_id <> ?
                  and (t.due_dt >= curdate() - interval 3 day
                        and t.due_dt <= curdate() + interval 3 day)
      $bind = array($p_project_id, $cancelled_id);
      $events = session_user()->dbh()->getAll($query,$bind);

Shouldn't it be something like
$session_user = session_user();

$bind = array($session_user->id);

what version of PHP do you use?
i think this syntax only works as from PHP 5 on, but not sure...

I think we would need to see the function 'session_user()' to be able to solve this one, since it is not a built in PHP function.
What does it mean to be "Always On"?

Okay also, on those lines shouldn't the operator be => and not ->?

When Changing it and running it I get:

"unexpected t_double_arrow"

Here's the Function:

function session_user()
      if (!isset($_SESSION))
            global $_SESSION;

      if (empty($_SESSION['user']) || !($_SESSION['user'] instanceof User))
            $_SESSION['user'] = new User;

      return $_SESSION['user'];

The '->' operator is the PHP Object Oriented Programming (OOP) method for accessing class methods/properties/etc... but can also be used for calling functions.  I'm not sure what they're trying to do in this script.  I agree with AngelIII - I don't think you can use this OOP method in PHP < 5.  I'm also not quite sure how to translate it to PHP 4.x.

That was it, PHP5. The Book I got the samples from was written previous to PHP5, why they would then put a CD together and release the code with PHP5 projects!?!?!?
