"newbie" question: what is =>

I've seen a number of code samples using something like:

a => get(this)

....and I can't find anything that explains what that symbology means. I
assume that is has something to do with an array, but I'm still struggling
to really get a good handle on arrays. Can anyone help me grasp what that is
and what it's used for?

Still learning,
Wm

OK, I kinda understand now -- it's pretty much like an assignment operator
(which is the section of the manual I was searching). Generally speaking,
array[a] = value is the same thing as array(a => value), right?

ya, that's right, but it would look more like:

$ararray['a'] = 5;
or
$ar=array('a'=>5);

Think of it as the "assignment arrow operator". There is also the "arrow"
operator, which gets stuff out of class instances:

$obj->methodName();

The "assignment arrow" can also be used in the following idiom, used to
iterate through an associative array:

foreach ($assoc_array as $key => $value){
print "KEY is $key , VALUE is $value<br>\n";
}

True?
I thought you only did >= & <=
and never
=< & =>

Looking at Comparison Operators,
the second set are not mentioned,
but if that works too :-)

Of course I could be wrong.

Watching people talk about their A level results is making me feel
like a total mong today.
