Accessing an Object on different page

[TomTees]

How do I access an object on different pages?

 

I created object "A" on pageone.php and I need to access it on pagetwo.php.

 

How do I do that?

You'd have to pass it through sessions.

You can pass an entire Object through a Session?? 

 

Is this safe?    :-\

 

Any "gotchas"?

 

Could you give me a snippet showing me how to do this?

 

Let's say I have...

 

class Ticket{

  private $price;

  private $destination;

}

 

$objTicket = new Ticket('$350', 'Miami');

 

on Booking.php and I need to have access to the object on RegistrationSummary.php

 

How would I do that using a Session??

 

Thanks,

$_SESSION['objTicket'] = new Ticket('$350', 'Miami');

 

Don't forget that your class definition needs to exist before the session_start() statement so that the object can be recreated from the session data file.

$_SESSION['objTicket'] = new Ticket('$350', 'Miami');

Hmm...  That is strange code?!

 

Why don't you declare the class and instantiate it using normal syntax and then assign it to a session?

 

<?php

  class Ticket{

    $private price;

    $private destination;

}

 

$objTicket = new Ticket('$350', 'Miami');

?>$_SESSION['objTicket']

Hi

 

You could also serialise the object and store it in a file (useful if it is common between different sessions)

 

All the best

Because it's the same.

 

class SomeClass {
  private $data = array('hello', 'world');
  
  function __toString() {
    return serialize($this);
  }
  
  function __sleep() {
    return array('data');
  }
}

 

$c = new SomeClass();
echo serialize($c), ' ', $c, "<br>\n";

$s = serialize($c);
$d = strval($c);
var_dump(unserialize($s));
var_dump(unserialize($d));

You guys are losing me here...

 

I was under the impression that if I store an Object in a Session then that is all I need to do (and then I do NOT have to Serialize the Object as well).

 

Is that correct?

 

I thought that is what the PHP manual said.

 

Also, what is the fascination with Serialization by some people?

 

From what I have read, Serialization is so "old school" and just using Sessions is better.
