What's with the arrows?

Facing to the

Imperial CMS is a process to write the PHP site, but I found it also useful in the use of arrows to write the statement, not to say, this type of arrow is oriented to the direction of the way, why in the process of the site also appear this arrow, do it have another meaning?
Here is the code
while ($BQR 2= $empire->fetch ($ecms _bq_sql2))
{
$BQSR 2=sys_returnecmsloopstext ($BQR 2);
$bqno 2++;
?>

You Print_r ($empire); Can you see what he is?

Why does this kind of arrow appear on the Web site of the process?
The shape of the top? It's a bit of a black and white feeling.

The result of my print_r is

I don't know what that means.

$empire must be an object.

I don't know what that means.

This indicates that $empire is a result set object after a MySQL database query. This object holds the results of the SQL statement query.

Mysqlquery Object is not the meaning
Is $empire an object derived from Mysqlquery?

I listen to QQ group said that this is a class, that is, the process has a class. I don't understand.

If you've used an ORM, a framework, and so on, you'll find that the object-oriented invocation in the process-oriented approach is actually too common.

Create an object, then assign the value, and finally save it, so you can:

$student =new student ();
$student->setname= ' Peter ';
$student->setsex= ' M ';

$entityManager->persist ($student);
$entityManager->flush ();

Object calls!!

Take a look at the object-oriented knowledge.

Isn't it better to be object-oriented?
