How can the use of global variables be optimized or minimized in PHP scripts, according to the recommendations in the forum discussion?

Global variables should be minimized in PHP scripts to avoid potential conflicts and improve code readability and maintainability. One way to optimize the use of global variables is by encapsulating them within classes or functions and passing them as parameters when needed. 

class Example {
    private $globalVar;

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

    public function doSomething() {
        // Use $this->globalVar here
    }
}

$globalVar = 'value';
$example = new Example($globalVar);
$example->doSomething();
