Difference between :: and -> in PHP
- by vrode
I always see people in serious projects use :: everywhere, and - only occasionally in local environment.
I only use - myself and never end up in situations when I need a static value outside of a class. Am I a bad person?
As I understand, the only situation when -> won't work is when I try following:
class StaticDemo {
private static $static
}
$staticDemo = new StaticDemo( );
$staticDemo->static; // wrong
$staticDemo::static; // right
But am I missing out on some programming correctness when I don't call simple public methods by :: ?
Or is it just so that I can call a method without creating an instance?
