Question

If I create a constructor function within my class with the variable called $base_url = 'mydomain'. How could I access this via other functions as a general variable?

I have tried creating a test function with echo $base_url but it did not return a variable.

Answer 1

Make it a class variable and reference it with $this

class MyClass {

    public $base_url; // change access modifier as needed

    public function __construct($base) {
        $this->base_url = $base;
    }

    public function getBaseUrl() {
        return $this->base_url;
    }

    public function url($url) {
        return $this->base_url . $url;
    }

}

$myClass = new MyClass('http://example.com/');
echo $myClass->url('register');

Output: http://example.com/register
