Global variable inside a constructor with PHP

Question

This should be obvious, but I\'m getting a bit confused about PHP variable scope.

I have a variable inside a Constructor, which I want to use later in a function in

Answer 1

You could use a class variable, which has a context of... a class :
(Example for PHP 5, of course ; I've re-written a few things so your code is more PHP5-compliant)

class Log {
   // Declaration of the propery
   protected $_myVar;

   public function __construct() {
      // The property is accessed via $this->nameOfTheProperty :
      $this->_myVar = true;
   }

   public function test() {
      // Once the property has been set in the constructor, it keeps its value for the whole object :
      $access = $this->_myVar;
   }

}

You should take a look at :

• The "Classes and Objects" section of the PHP manual
• And, for this specific question, the sub-section Properties
