Marek -
Thanks for your help.
Unfortunately, my ignorance is more extensive than I had believed. In your
reply, ... echo 'Q::qzml() ... what is the signifigance of '::'? I've only
thought of such a figure as expressing a ratio.

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';
}
}
$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.

But as for the first question, I don't know if '->' or '=>' have any
specific *names* in PHP.
