Question

Code example:

<?php // class_database.php
class database
{
include("class_validation.php"); //this does not work
$val = new validation() //this does not work
    public function login($value)
    {
if($val->validate($value))
{
//do something
}
    }
}

<?php // class_validation.php
class validation
{
    public function validate($value)
    {
if($value > 50) return true;
return false;
    }
}

How do I delegate the class validation in class database?
I do not wish to inherit (implement or extends) the class validation -> behavior in validation is not to be changed.
I just want to use the methods from validation class. Any OOP solutions?
Thanks in advance

You cant use include inside a class like that! Either include it at the beginning of the file ( my suggestion ) or use it one line before $val = new validation(); call.

class_database.php:

<?php
    include("class_validation.php");

    class database
    {
        public function login($value)
        {
            $val = new validation();
            if($val->validate($value))
            {
                //do something
            }
        }
    }
?>

 
class_validation.php:

<?php
    class validation
    {
        public function validate($value)
        {
            if($value > 50)
                return true;

            return false;
        }
    }
?>
