Question

 if (isset ($_POST['somethingA']))
 {
      //code for doing something A
 }
 elseif (isset ($_POST['somethingB']))
 {
      //code for doing something B
 }

I will need to access some data from somethingA code, into somethingB code.

How can I do that in a proper way?

Should I declare a variable outside the conditionals, work inside the conditionals, and later (bottom) I use that?

Should I work with them inside the conditionals, and, somehow, pull them out after the conditional lines?

Thanks in advance,

you may do something like you said:

$innervar = null;

if (isset ($_POST['somethingA']))
 {
      $innervar = new A();
      //code for doing something A
 }
 elseif (isset ($_POST['somethingB']))
 {
      $innervar = new B();
      //code for doing something B
     }

$innervar->CommonMethod();

If you are accesing $_POST directly consider using some sort of framework like symfony, or Zend, unless you are learning or working in a very simple(house) project.

Best of luck
