I'm one of the ignorant multitude beginning to grope their way across

the threshhold of web programming. I come from another world, not computer science, and thus have a question so basic I haven't found any reference to it anywhere. It's killing me.

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: http://sk.php.net/manual/en/function.array.php

Any help would be greatly appreciated. Thanks, -Paul
