And really, you're not talking about a caller object but about accessing
variables in scope from the next-highest step in the call stack, which may
or
may not be an object. (Hybrid language, remember. It could be a lambda
function as of PHP 5.3, or global scope, or...) ...
function foo()
{
$caller = get_caller(); // returns standard PHP callback format
}
Results with various caller contexts:
// instance method
array(object $instance, string $methodName)
// static method
array(string $className, string $methodName)
// function
string $functionName
// closure
object $instance (instance of Closure)... or alternatively: array(object
$instance of Closure, string "__invoke__")
// global scope
null
