Edit Question
Title
Body
I'm new to the OOP paradigm, so there's probably a simple explanation for this question... Do you always need to declare public object-wide variables in a class? For example: <?php class TestClass { var $declaredVar; function __construct() { $this->declaredVar = "I am a declared variable."; $this->undeclaredVar = "I wasn't declared, but I still work."; } function display() { echo $this->declaredVar . "<br />"; echo $this->undeclaredVar; echo "<br /><br />"; } } $test = new TestClass; $test->display(); $test->declaredVar = "The declared variable was changed."; $test->undeclaredVar = "The undeclared variable was changed."; $test->display(); ?> In this code, even though $declaredVar is the only declared variable, $undeclaredVar is just as accessible and useable--it seems to act as if I had declared it as public. If undeclared class variables are always accessible like that, what's the point of declaring them all up front?
