prevent class destruction being called at the end of script

[nekokumi]

hi again

 

i have question again. please see the simplified code, my question and explanation is in the comment in code.

 

if ($_POST['test']) {
  if (isset($_SESSION['a'])) {
  $a= $_SESSION['a'];

  $a->say($_POST['test']);  
// say() function doesn't work as expected because $a destructor already being called in end of script, so some needed variable are freed.
// i would like the $a destructor called here
  unset($_SESSION['a']);
  }
} else {

  $a= new test();	
  $a->get_something_and_display_it();

  $_SESSION['a'] = $a;
                

  echo "<form action='test_create2.php' method='post'>
  <input type='text' name='test'>
  <input type='submit' value='Enter text'>
  </form>";
                
             
// $a test() class destructor is called here, but i'm planning to use $a variable method after the page posted
// and that's why i saved the $a variable into a session.
// i would like to prevent $a destructor being called here.
}

 

there is a way i think, moving the destructor into a method like free();

 

but is that the only way / correct way?

i need your help and suggestion guys

 

thank you

update:

i try moving the destructor content into free() method also doesn't work because the whole class being destructed at the end of script.

Web servers and any server side scripting languages used on them are stateless. All resources that a php script uses are destroyed at the end of code execution on a page.

 

If you want to carry information between pages it must be specifically stored or passed between pages (database, flat-file database, session data file, parameters on the end of the url, cookies...)

Thanks for your reply.

Yes, that's why i saved it the variable into a session variable. here is another example what i am doing to be more clear:

 

page: a.php

 

- $a = new test();

- save $a into session['a']

 

(page a.php ends, $a destructor are being called)

 

page: b.php

 

- $a = session['a'];

- $a->some_method(); // Failed, because some of the variable inside test() class already freed, when page a.php ends.

Make sure your class definition exists in the script before the session_start() on the second page.
