Whether you are learning or new to porgramming in PHP there are a dozens of important php functions you should get hold of at first.
This will make your life lot easier if you know about these functions. And you should remember them by heart if you want to be very very good programmer because with time you could do the same with any other language.
Most of programmers who want to be serious in development field lack the courage to do the first step right, which is to be master in the basics functionality of any language. And believe me the easiest task on any programming language is basically connecting to a database, and execute some quries, list data etc.)
But when life becomes tougher, we encounter logic and write code for a very complex task, these functions are our babies which we should love most... Because, like a good child, these functions are going to save us the way our children do in our old-age.
