PHP: Object assignment to static property, is it illegal?

Question

Is it illegal to assign some object to static property?

I am getting HTTP 500 error in below code.

require_once(\'class.linkedlist.php\');

class Sin         


        

Answer 1

You can't create new objects in class property declarations. You have to use the constructor to do this:

class SinglyLinkedlistTester {
    public static $ll;

    public function __construct() {
        static::$ll = new Linklist();
    }
}

Edit: Also, you can test your files for errors without executing them using PHP's lint flag (-l):

php -l your_file.php

This will tell you whether there are syntax or parsing errors in your file (in this case, it was a parse error).
