looking up db flags

Im guessing its a function that goes in the dbnpc script, and I call it to show up the items for the category selected, but if an explanation line by line is possible with comments or something, that would be great.

PHP Code:

public function getCategoryListing(temp.category){
  clearemptyvars(); // Removes any empty variables in the npc, for example: it would remove 'this.var1= ' if it existed for some reason (usually pointing to an empty object when that happens).
  temp.list = {}; // Create an array outside of for-loop scope so it can be used inside of the for-loop and also outside of it (for the return value).
  // This first for loop will loop through all variables starting with this.item.(temp.category).* where temp.category is the parameter passed in the function and * is anything. For example: if temp.category="pie" then it would loop through all variables starting with 'this.item.pie.' I will explain getdynamicvarnames() below.
  for (temp.acnt: this.item.(@temp.category).getdynamicvarnames() ) {
  // This for loop will loop through similarly to the one above, using the value that was found from 'this.item.(@temp.category).getdynamicvarnames()' to look for deeper variables.
    for (temp.item: this.item.(@temp.category).(@temp.acnt).getdynamicvarnames() ){
      // temp.v is equivalent to 'this.item.(@temp.category).(@temp.acnt).(@temp.item)' in order to shorten it because it will be used several times for temp.list.add().
      temp.v = this.item.(@temp.category).(@temp.acnt).(@temp.item);
      // Add values to the list in their respective order.
      temp.list.add({ temp.item, temp.v[0], temp.acnt, temp.v[3] });
    }
  }

  return temp.list;
} 


var.getdynamicvarnames() returns a list of all variables that exist starting with 'var.' This can be used in several ways, for example, to return all client.variables, you could do:

PHP Code:

//#CLIENTSIDE
function onCreated() {
  for (temp.i: client.getDynamicVarNames()) {
    echo("client." @ temp.i @ " = " @ client.( @ temp.i));
  }
} 


Personally, I don't think you should follow the suggestion given above because it seems needlessly complicated unless you fully understand what is going on within the code.
