Pass var from one class to extended class

[ziycon]

I need to pass a var from the parent class to an extend class but need it to keep the value that was set during the running of the main class. the code i have so far is below but isn't keeping the value from the parent class.

The problem is getting the 'v1' value passed to the ext class to use it in a SQL query. Any ideas??

class main {
   var $v1;

   function __consturct() {
   }

   function someFunc() {
      ..do stuff..

      $v2 = &new ext($this->v1);

      ..do stuff..
   }
}
class ext extends main {
   ..do stuff..
   ..get v1 value from parent class..
   ..use v1 value in SQL query and insert values returned..
}

It's there.

$v1 doesn't have a value though.

Here is a little example.

<?php
	class main {
	   var $v1= "test";
	 
	   function __consturct() {
	   }
	 
	   function someFunc() {

		  $v2 = &new ext($this->v1);
	   }
	}
	class ext extends main {
		function showVar ()
		{
			return $this->v1;
		}
	}


	$myExt = new ext();
	echo $myExt->showVar();
	echo "<br />" . $myExt->v1;
?>

I meant to say that $v1 does have a value set in the parent class that needs to be passed to the extend class, is there a way to do this?

class main {
   var $v1;

   function __consturct() {
   }

   function someFunc() {
      ..do stuff..

      $this->v1 = "string";

      $v2 = &new ext($this->v1);

      ..do stuff..
   }
}
class ext extends main {
   ..do stuff..
   ..get v1 value from parent class..
   ..use v1 value in SQL query and insert values returned..
}

Did you try my example?

Line 16 shows you how to access the variable. It is important that the parent class' constructor is called before inherited variables can be accessed.
