如何在某些条件下做两个平等的陈述？

Question

I need to use different modules based on what value the $what variable holds. There are 2 variables; me and others. If $what = me i want them to see me.php an if $what = others i want them to see others.php. I don't know how to update the snippet that will also take $what = other scenario under consideration.

How to do that?

  $what = "me";

  if ( $q === $what ) {
require("me.php");
  } else {
  require("all.php");
  }

Answer 1

You need elseif statement.

 $what = "me";

 if ( $q === $what ) {
    require("me.php");
 } elseif ($what === "others") {
    require("all.php");
 } else {  // optional "catch all condition"
   die("Should not be here");
 }
