What are the best practices for organizing and structuring PHP code to avoid variable conflicts and scope issues?

To avoid variable conflicts and scope issues in PHP, it is best practice to use namespaces to organize your code and prevent naming collisions. Additionally, using classes and objects can help encapsulate variables within a specific scope, reducing the likelihood of conflicts. 

<?php

namespace MyNamespace;

class MyClass {
    private $myVariable;

    public function setVariable($value) {
        $this->myVariable = $value;
    }

    public function getVariable() {
        return $this->myVariable;
    }
}

$myObject = new MyClass();
$myObject->setVariable('Hello, World!');
echo $myObject->getVariable();

?>
