What is faster: many ifs, or else if?

Question

I\'m iterating through an array and sorting it by values into days of the week.

In order to do it I\'m using many if statements. Does it make any differ

Answer 1

I made a benchmark if there's a true difference between successive if() and if() then a few elseif()

I put a big string and did about 20 strpos() each time (x100 000) with the two methods and it showed this result :

Try 1 : 0.5094 (including elseif)
Try 2 : 0.6700 (including only if)

There's no doubt. I already knew sucessive elseif() were faster, even though there's a return in the middle ; it's still good to put some statistics in the answer.
