Guidline's of basic programming

[gvanaco]

does someone now an artikle that explain how you have to program a Language (PHP).

For example I will now what's faster a WHILE or an IF function.

Dear Friend,

search in google.com with the key words

That's not what I'am searching or interested.

More the speed of the algotitme (english ?)

Well, you could always write it both ways and have a timer to time how long it takes to see.

I imagine an if will be quicker than a while because a while has extra functionality however I really wouldn't bother wasting time over it, there are going to far bigger bottleknecks than the difference between an if and while.

Sometime's I have to made the desision to make a very complex query into the database, or a lot of easy if and while statements.

I saw a few time's that there is a big differents between the process time.

Because I never used a book or classes (shool), I will now learning the real basic programming.

SQL queries and PHP statements have nothing to do with each other.

As bubblenut said, worrying about which of several PHP constructs might be faster is entirely the wrong thing to do. First, write clean code. There is a saying: "Premature optimization is the root of all evil."

Your bottlenecks are likely to be related to i/o operations.

Worrying about database performance IS the right thing to do, but it's not so much a matter of how you construct your queries (the database can optimize that), but rather how you construct your data model and index your tables.
