Where and why do we use __toString() in PHP?

Question

I understand how it works but why would we practically use this?

Answer 1

it's like override with c# :

class Person

{

public Person(string firstName, string lastName)

{

FirstName = firstName;

LastName = lastName;

}

public string FirstName { get; set; }

public string LastName { get; set; }

public override string ToString()

{

return FirstName + “ “ + LastName;

}

}
