PHP - Object of class could not be converted to string - php

Question

I'm trying to print a property of the simple class below. But instead i get the error above. I haven't found an answer on similar questions on here. The error triggers on this line:
echo "$object1 name = " . $object1->name . "<br>";
Using XAMPP on Windows Help?
<?php
$object1 = new User("Pickle", "YouGotIt");
print_r($object1);
$object1->name = "Alice";
echo "$object1 name = " . $object1->name . "<br>"; /* this triggers the error */
class User
{
public $name, $password;
function __construct($n, $p) { // class constructor
$name = $n;
$password = $p;
}
}
?>

Answer 1

There are two things wrong in your code,
You're using local variables in your class constructor, not instance properties. Your constructor method should be like this:
function __construct($n, $p) {
$this->name = $n;
$this->password = $p;
}
Now comes to your error, Object of class could not be converted to string. This is because of this $object in echo statement,
echo "$object1 name = " ...
^^^^^^^^
You need to escape this $object1 with backslash, like this:
echo "\$object1 name = " . $object1->name . "<br>";

Answer 2

In my case the problem was the way I was initializing the class variable.
This was my code :
public function __construct(User $userObj) {
$this->$userObj = $userObj;
}
and I solved it by changing it to the following :
public function __construct(User $userObj) {
$this->userObj = $userObj;
}
The line in the first snippet caused the problem : $this->$userObj = $userObj
