How to save the array vars in a class?

Hi,
I'm using serialize to save an object which worked until I started using Arrays in the class. Please see this code below:

class Base extends Tile

{

 var $owner;

 var $resources = Array();

 

 function Base($owner)

 {

        $this->Tile();

        $this->owner = $owner;

 }

 function __sleep()

 {

   // used this before which works for simple vars like owner

    //return array('owner');

   // trying this now but doesn't seem to work for arrays

        return( array_keys( get_object_vars( &$this ) ) );

 }

}

Then you would just call serialize and unserialize.

But like I commented that doesn't work, the array is not saved.
Any suggestions what could I try?

Thanks.

Can you show your serialize and deserialize code? I have never heard of problems with those functions working with arrays, and the code you have shown me does necessairly indicate anything I would see as an error--yet.

Sure kurifu, thanks for looking into this!

first the $map is initialized like this: $map = array();
and filled with new Tile()

this is how the map is saved:



saveGlobal('map',$map);



for($y = 0; $y < MAP_HEIGHT; $y += 1)

{

 for($x = 0; $x < MAP_WIDTH; $x += 1)

 {

        $tile = $map[$y][$x];

        if(!isset($tile))

         exit("tile $x $y not set");



        saveGlobal("m$x$y",serialize($tile));

 }

}

this is how it's loaded:



$map = loadGlobal('map');

 

for($y = 0; $y < MAP_HEIGHT; $y += 1)

{

 for($x = 0; $x < MAP_WIDTH; $x += 1)

 {

        $s = loadGlobal("m$x$y");



        $map[$y][$x] = unserialize($s);        

 }

}

And here are the functions used:

 



function saveGlobal($varname,$value)

{

 $_SESSION[$varname] = $value;

}



function loadGlobal($varname)

{

 return $_SESSION[$varname];

}

The problem should not be in the session code I think because everything else works except the array saving.

Thank you, please understand that I am a beginner at php and more of an C++ coder so please feel free to comment the code, it would help me.
