Good question. The require() call does not seem to distinguish...coding standards maybe?

It looks as if they're the same, but I could be wrong. It may accept all formats for backwards compatability, or maybe that type of statement was never strongly defined...maybe skyhawk, sloth or cyberscribe know?

The advantage of require to echo etc. is that you can use vars (like configs, templates) more often without needing it to program into every page you need it.
Also once you do it this way you will only have to change 1 file and have the changes be taken throughout all pages where that file is being required.
So there can be an advantage if there's a purpose for it. It won't make much of a difference on one page if only for making the code more accessible.

I belive he was asking the difference between calling require() with the brackets, or using the quotes...I could be very wrong about that.

I took it the way amadeus did.

I never really noticed, but I always the the ()'s out of habit. That was one of the weird things about moving to coldfusion because it almost exsclusively uses the ""s.

According to the Pear coding standards, the correct form is actually:

CODE

require 'global.php';


Because:
  • Require is not a function but more of a built-in directive
  • Single quotes are preferred for strings with no special characters or variables to evaluate
I'm currently writing a 3-part entry on practical coding standards:

Because some standards are really useful and some are just a matter of style. I'm trying to distill it out.

I think my habit too is coming from a c++ background, especially since i tended to lean towards system commands in a lot of my work.
