Check rule/object first before applying PHP API

RouterOS Scripting
1

Hi,

I am having a bit of a problem with updating rules on my router via PHP API, how can I make my code first check if there is a difference in the setting for example first check the router if the rule/object is disabled and then apply or do nothing if everything matches perfectly.

Currently whenever my sync script runs, it keeps readding(updating) the rule/object on the router when it doesn’t need to because the code already has the same info that is already configured on the router.

Current code:

function update_routerOS_address_list($list, $address, $comment) {
		//Set globals
		global $API;
		global $Debug;

		$API->write('/ip/firewall/address-list/print',false);
		$API->write('?comment='.$comment,true);
		$READ = $API->read(false);
		$ARRAY = $API->parseResponse($READ);
		if(count($ARRAY)>0){
			$API->write('/ip/firewall/address-list/set',false);
			$API->write("=.id=".$ARRAY[0]['.id'],false);
			$API->write('=disabled=no',true);
			$READ = $API->read(false);
			$ARRAY = $API->parseResponse($READ);
		} else {
			$API->write('/ip/firewall/address-list/add',false);
			$API->write('=list='.$list,false);
			$API->write('=address='.$address,false);
			$API->write('=comment='.$comment,true);
			$READ = $API->read(false);
			$ARRAY = $API->parseResponse($READ);
		} 
	}
