What does the PHP syntax $var1->$var2 mean?
Reference - What does this symbol mean in PHP?

I'm looking at a PHP framework's code, and now and then the symbols "->" appear... for example:

$controller->permissionCheck($ret);

What does "->" stand for and what is used for?

Answer 1

In your example, $controller is a PHP object created somewhere, and permissionCheck is a function defined in that object that is being called with the variable $ret being passed to it. Check this: Reference - What does this symbol mean in PHP?.
