What best practices should be followed to avoid variable redeclaration issues in PHP classes?

Variable redeclaration issues in PHP classes can be avoided by following best practices such as using unique variable names within the class scope, utilizing proper encapsulation techniques like private or protected visibility, and avoiding global variables. Additionally, utilizing constructor parameters or class properties can help prevent variable redeclaration conflicts. 

class MyClass {
    private $variable;

    public function __construct($variable) {
        $this->variable = $variable;
    }

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