include "Services.php";

OR

require "Services.php";

• How can i call its functions in myFile.php

Answer 1

Just call them the same as you would any other function:

serv1(42);

Answer 2

You should just be able to call serv2(3) or whatever need be.

Answer 3

You can just call any of these functions. After the file is included, the functions will be placed in the global scope.

have you not tried:

include "Services.php";

$num = 123;

serv1($num);

From the doc:

When a file is included, the code it contains inherits the variable scope of the line on which the include occurs. Any variables available at that line in the calling file will be available within the called file, from that point forward. However, all functions and classes defined in the included file have the global scope.

Check out these two doc resources for more information on what you're having trouble understanding:

• include statement: http://php.net/manual/en/function.include.php
• variable scope: http://php.net/manual/en/language.variables.scope.php
