Instantiate your static variables in the library file. Again, so that only happens once. functions implemented using objects sounds like exactly what I want. Just out of curiosity, and sorry in advance for my ignorance, but does the code I posted fit that type of pattern? If not, what would I need to modify and how would I call it? Actually, I should probably spend some time Googling before I ask you for more details. :D Well, your code does not take advantage of the features of classes, but the syntax is correct. Global, static variables are not consistent with the design concepts of OOP. But as a first step in moving from procedural code to OOP, which is learning the syntax, go for it. -- Stephen ---End Message--- ---BeginMessage--- Thanks Stephen! I really appreciate the help! :) In my PHP ventures over the years, I haven't made much use of static variables/methods/properties ... I was thinking they might be useful for this one bit of code, but based on your feedback (and David's) I think I'll be heading down a different path. Thanks again for the kick in the right direction! Much appreciated! Cheers, Micky ---End Message--- ---BeginMessage--- Hi, first, sorry for the bad English. Yes, at least, as far as I know, this is the perfect way to do what you want to do. Think like this: when you instanciate a class, you are allocating memory. If you don't need any information stored, then you don't need to allocate memory, right? So, it's is logic to have a class that you will call only one fragment when you need it, rather than load the entire class just for one method. Just be careful to organize your utility methods by by meaning. Don't put a method that make dating stuff and a method that write a random string in the same class. By doing so, you are breaking the object orientation purpose. 2013/9/4 Micky Hulse mickyhulse.li...@gmail.com Hi all! Example code: https://gist.github.com/mhulse/6441525 Goal: I want to have a utility class that contain utility methods which should have the option of being called multiple times on a page. I think my main goal is to avoid having to new things ... I don't really need to create an instance here (there's no need for a constructor in this case). Question: Is the above simple pattern a good way to have a class that calls static methods? To put it another way, is there any reason why I would not want to use the above code? Basically I want to wrap these simple functions in a nice class wrapper and have the ability to call them without having to jump through more hoops than is necessary. Are there any pitfalls to writing a class like this? Or, is this the standard way of writing a simple utility class for this type of situation? Please let me know if I need to clarify my questions. Thanks for your time? ---End Message--- ---BeginMessage--- Hi Rodrigo, thanks for the help, I really appreciate it!

A part of me just wants to learn more about PHP OOP, and using static members is something I've not explored much. Seems like a simple functional utility class would be a good time to play and learn more. :D Just be careful to organize your utility methods by by meaning. Don't put a method that make dating stuff and a method that write a random string in the same class. By doing so, you are breaking the object orientation purpose. Excellent tip! Thank you Rodrigo! I really appreciate the tips/advice and inspiration. :) I'll second Rodrigo's opinion, but would like to comment that the name of the class is misleading since it's called Singleton. The singleton pattern is used when you only ever want one instantiation of a class. In your case you are using static methods, the object never needs to be instantiated and so it doesn't fit this pattern. What you are creating is far more consistent with the utility pattern.

Juan, the problem with this list is that that there are too damn many dumb questions. You did something nice but it doesn't stand out. You can check Symfony2 DiC. You can use it as a stand alone component.
