In the php statement
$q->qzml();
what is the symbol '->' called? What does it mean?
It calls *member* function of object $q. So even if qzml is a global 
function it will not work, the function must be defined in the object's 
class definition:

class Q {

        function qzml() {
                echo 'Q::qzml() function<br>';
        }       
}
$q=new Q;

$q->qzml();

A php script with this line in it, in which $q is an object and qzml() is a function, returns the error message "undefined function". When I remove this line, the function qzml() is recognized.

I have also come across the symbol '=>'. I assume it is not the same symbol. What is it, and what does it mean?
It is used to assign values to keys in array() construct:

Any help would be greatly appreciated.
