PHP: Global variable scope

Question

I have a separate file where I include variables with thier set value. How can I make these variables global?

Ex. I have the value $myval in the v

Answer 1

Using the global keyword in the beginning of your function will bring those variables into scope. So for example

$outside_variable = "foo";

function my_function() {
   global $outside_variable;
   echo $outside_variable;
}
