I'd like to call a static function of class A, in class B by passing it via Start.php as a parameter, but without including the ClassA.php into ClassB.php.
The reason I want to do this is because I have some client-specific logic, that i want to separate and call centrally and only when I really need it (index.php) without including it in the other files.
Let's say I've 3 files.
Start.php, ClassA.php, ClassB.php
ClassA.php
class A {
public static function foo($param) {
// do some special logic
// and return either true or false
}
}
ClassB.php
class B {
function bar($var, $func) {
foreach($var as $v) {
if($func($var)) {
echo 'OK';
}
}
}
}
Start.php
require_once('ClassA.php');
require_once('ClassB.php');
class Start() {
function init() {
$b = new B();
$test = array(1,2,3,4,5);
$b->bar($test, ['A', 'foo']);
}
}
Start::init();
So, Start depends on ClassA and ClassB, that's OK.
But I don't want ClassB to depend on ClassA.
When I do it like this, I get error, saying that Class A cannot be found.
Is that possible? Is that even considered as good practice?
