PHP Declaring and Accessing Properties

Declaring and Accessing Properties

Properties are declared in PHP using one of the PPP operators, followed by their name:

class foo {

public $bar;

protected $baz;

private $bas;

public var1 = "Test"; // String

public var2 = 1.23; // Numeric value

public var3 = array (1, 2, 3);

}

Note that, like a normal variable, a class property can be initialized while it is being declared. However, the initialization is limited to assigning values (but not by evaluating expressions). You can’t, for example, initialize a variable by calling a function—that’s something you can only do within one of the class’ methods (typically, the constructor).
