Hope everything is good.
Let's say I have this object x 200 (with different values, of course)
 => stdClass Object ( [Manufacturer] => Nike [Name] => Air Max Talldress [Options] => stdClass Object ( [Black] => Array (  => Medium  => Large ) [White] => Array (  => Small ) ) )
I only want all objects where "Manufacturer = Nike". How should I do to ONLY compare with the "Manufacturer" property, without wasting time on properties that are not relevant in this case. Optimize the process.
I'm not interested in dbms, I want to see what's possible here.
