array_unique for objects?
arrays, methods, php
Solution
Well, `array_unique()` compares the string value of the elements:
Note: Two elements are considered equal if and only if `(string) $elem1 === (string) $elem2` i.e. when the string representation is the same, the first element will be used.
So make sure to implement the `__toString()` method in your class and that it outputs the same value for equal roles, e.g.
class Role {
private $name;
//.....
public function __toString() {
return $this->name;
}
}
This would consider two roles as equal if they have the same name.
Problem
Is there any method like the array_unique for objects? I have a bunch of arrays with 'Role' objects that I merge, and then I want to take out the duplicates :)
