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

To be honest I don't think it would matter which way you do it in terms of performance, I doubt you would see any difference. I would recommend using a switch statement which isn't a performance enhancment, simply syntactically nicer:

switch ($day) 
{
    case "Monday":
        // do something with Monday
        break;
    case "Tuesday":
        // do something with Tuesday
        break;
    case "Wednesday":
        // do something with Wednesday
        break;
}
