PHP how to call function from another class?

Question

I have a class Database in database.php with 145 functions(17,000 lines) and now i've read this is bad practice, so i want sort out the functions correctly into specific classes rather than a "God" Class.

What i want to know is how do i call a function from another class? Below is an example; How do i call function two from within function one?

database.php

require("connect.php");

class Database {
private $connect;

function one() {
//call function two
}

}

forms.php

require("connect.php");

class Forms {
private $connect;

function two() {
//returns forms
}

}

How do i do this?

How do you usually call functions of a class? You create an object and then? :) — N.B.

You'd have a problem if you did that. Both files require connect.php User require_once instead — Nathan Dawson

So should i remove require connect.php from forms class? In forms class i also connect to the database. — user892134

In the example you gave you would do:

function one() {
    $forms = new Forms;
    $forms->two();
}

Another option would be

function one() {
      Forms::two();
   }

And in Forms you would change the method to:

static function two() {

   }
