Why use only one return statement per function?

[gr4devel]

Hi community .

 

A very general question.

 

What is your personal preference concerning the use of only one return statement per function.

 

In the past I've been used to this coding style but now I really appreciate the brevity that multiple return statement in a function (or object method) grant me when writing code and as a result I used it a lot when writing my modules.

 

Now I'm particularly worried about going against the coding standards suggested by PS.

 

How about you guys?

 

 

P.S: if the post isn't placed in the right position in the forum or if the topic isn't right for the forum itself please forgive me and notify me so that I can remove it

as far as i know - in PHP there is no way to return 2 or more variables.

you can return an array of variables (but it is still one variable)

 

for example return array($var1,$var2,$var3);

mmm...wait I think I didn't explain myself.

 

I don't mean to return multiple values but to use multiple return statement in different positions in a given function or method.

 

e.g:

 

function A ($a) {
if($a)
return 'hi';
return 'bye';
}

 

Sorry for the lack of my precision.

for me - everything is fine in this code. Im using these statements.

I don't know why you think that you're going against the coding standards suggested by PS

 

in my opinion

if your code is compatible with php - you definitely don't have to worry

Nice to know my friend .

 

I was worried about the "We recommend one return per method/function." that I've found reading the coding standards (http://doc.prestashop.com/display/PS15/Coding+Standards#CodingStandards-Returnvalues).

 

However let me thank you as always for the participation to this topi
