Iv nesne yönelimi etrafında başımı almak için çalışıyor ve ben iv bazı kavramların almaya başladı düşünüyorum, ama emin değil im. Soru herhangi kurallara aykırı ise düşünce benim tren ben burada gerçekten hızlı sormaya karar verdim oldukça zor olduğunu kanıtladı doğru olup olmadığını cevapları bir google arama yapma, lütfen söyle.
Im I thinking correctly in regards to messagepassing? What are the obviously bad things? How should I think while going forward with my learning?
Like getpagecontent($page, $connection); etc
Atm im reading [Oreilly - Learning php and mysql][1] and [Programming in an Object-Oriented Environment][2] And some books on UML
İşte kodudur.
