Class not used as an object (Scope Resolution Operator)

Hi all. Am fixing some inherited code, and the previous coder created a class, ie: class myClass { function &doThis($passedVar) { doSomething; } function &doThat($anotherVar) { doSomethingElse; } } BUT, I don't see anywhere where he created an object, ie: $myObject = new myClass(); or $myObject = myClass::doThis("value"); Instead, it's only ever just called directly with a "Scope Resolution Operator", ie: myClass::doThis("valueOne"); myClass::doThat($whatever); myClass::doThis("valueTwo"); myClass::doThat($andSoOn); It seems that this would be making an object, and then destroying it again, on each of the four calls above, which I would think would be wasteful - time, memory, cpu usage, etc. The class has no constants or variables (properties) for any need for persistence, and is just a collection of functions (methods), so I don't see a reason to group them into a class - they could all reside as independent functions within the php file. Is this good? Is there some advantage to making a non-persistent class? Thanks! George Langley    Multimedia Developer    Audio/Video Editor    Musician, Arranger, Composer
