Looping logic

[Nieeru]

Hey there! Quite new to the forums so, be kind. 🙂

I'm creating this script that reads an external XML file and populates a database.
There are 10 different class ID's (1, 2, 3, 4, 5, 6, 7, 8, 9 and 11) and I'm defining variables as true for every occurance of class ID before looping.

While in the loop, what I want to achieve is counting the class ID's, if for instance there are no members with class ID 1 I want to tag it's variable as false, however, it's not really going my way.

So far, I've tried doing this in a few ways.
- With the returned mysql information, doing checks in a while loop
- Exported the returned mysql information in to a single array and doing checks in a foreach loop.

I know I could simply use mysql and make a query for every class ID, then tag them as true/false, but, there has to be an easier way then having to define everything ~10 times.

Home there's someone out there who has an idea what I'm talking about! Cheers.

Does this sort of thing do it for ya?

<?php

// dunno how you're setting all true, but for example:
   $ck=array(1=> true,2=>true,3=>true,4=> true,5=>true,6=>true,
   7=>true,8=>true,9=> true,11=>true
   );

// these are values we wish to check for
   $check=array(1,2,3,4,5,6,7,8,9,11);

// sample data (in your case, this is from a DB)
   $data=array(7,8,9,10,11);

foreach ($check as $c) {
   if (in_array($c,$data)) {
      $ck[$c]=0;
   }
}
// output
print_r($ck);
?>

Probably not very elegant, quick test seems to indicate it might work though.

dalecosp: I thought about maybe doing something like that, but I were unsure as to how I would go about doing it.

It worked like a charm! I'll try finish the script once I get back from Uni. and share it. 🙂
