[Mapserver-users] creating class dinamicaly from mapscript: how could if works without failing?

[Eduardo Patto Kanegae]

I'm using PHPMapScript to generate classes for a given layer using the following code:

while (!$vwCommPlaceTypes->EOF){
 	$stClass = ms_newClassObj($hTmpLayer);
	$stClass->set("name",$vwCommPlaceTypes->fields["tip_descricao"]);
	$stClass->setexpression("(('[TIP_CODIGO]' eq '".trim($vwCommPlaceTypes->fields["tip_codigo"])."') AND ([FLAGS] > 0))");		
	$vwCommPlaceTypes->MoveNext();
}

and the final step is $map->save()

but i'm curious: how this work so well if for each iteration of the loop a new class is created inside the same var-name: $stClass ???

I mean, if I have 10 reccords in table, this code generates me 10 classes at the saved mapfile.

in teory I was waiting this code will failed, cause I thougt that 'stClass' will have only the last class object.

but is not what happens. it's a trick of PHP or MapScript API?

thanks
