How can I update a single user, like adding firstname, lastname, etc?

foreach ($users['User'] as $my_object)
{
    $email = (string)$my_object->email;
    $my_associative_array[$email] = $my_object;
	
}

Please post the class definition used when the script instantiated $my_object.  I will show you how to add properties and setters.

<?php

class User {
	public $email;
	public $firstname;
	public $lastname;
	
	public function __construct($email, $firstname, $lastname)  
    {  
        $this->email = $email;
	$this->firstname = $firstname;
	$this->lastname = $lastname;
    } 


	public function setEmail($value)
	{
		$this->email=$value;
	}

	public function getEmail($value)
	{
		return $this->email;
	}

	public function setFirstname($value)
	{
		$this->firstname=$value;
	}

	public function getFirstname($value)
	{
		return $this->firstname;
	}

	public function setLastname($value)
	{
		this->lastname=$value;
	}

	public function getLastname($value)

That cannot possibly be the class definition.  It contains a parse error on line 38.

But that aside, here is the way you do it.  Take note of a few code changes.  See

<?php // RAY_temp_glynco.php
error_reporting(E_ALL);
echo "<pre>";

// CLASS DEFINITION
class User
{
    public $email;
    public $firstname;
    public $lastname;

    public function __construct($email, $firstname, $lastname)
    {
        $this->email = $email;
        $this->firstname = $firstname;
        $this->lastname = $lastname;
    }

    public function setEmail($value)
    {
        $this->email=$value;
    }

    public function getEmail()
    {
        return $this->email;
    }

    public function setFirstname($value)
    {
        $this->firstname=$value;
    }

    public function getFirstname()
    {
        return $this->firstname;
    }

    public function setLastname($value)
    {
        $this->lastname=$value;
    }

    public function getLastname()
    {
        return $this->lastname;
    }
}


// MAKE AN ARRAY OF OBJECTS
$arr[] = new User('Ray.Paseur@Gmail.com', 'Ray', 'Paseur');
$arr[] = new User('NoReply@Gmail.com', 'No', 'Reply');

// SHOW THE ARRAY
var_dump($arr);

// UPDATE ONE OF THE OBJECTS
foreach ($arr as $key => $obj)
{
    // FIND THE OBJECT WE WANT TO UPDATE
    if ( (string)$obj->getLastName() == 'Reply' )
    {
        // MODIFY THE OBJECT
        $obj->setFirstName('Bill');
        $obj->setLastName('Gates');

        // REPLACE THIS ELEMENT OF THE ARRAY
        $arr[$key] = $obj;
    }
}

var_dump($arr);
