Rami,
There are all kinds of conventions for formatting code. Steve gave you
one, and one of the most popular.
Look at some of the example code in the PHP manual, for instance. And
other code posted here in the newsgroup and around the net.
Not all of it adheres to the same conventions, but you'll soon recognize
many of them.
I like this convention because it makes the code much easier to read and
understand. For instance, I find putting the "then" clause on the same
line as the "if" statement more difficult to read. I guess mainly
because the "if" statement is always executed, but the "then" clause may
or may not be. Placing it on another line helps clarify that.
And indenting under "if" statements, loops, function definitions, etc.
are a very good way to help see program flow.
