php run method and get variable in one line - class

Question

I want to get variable after running class function. I usually do it in 2 lines:
$object->function();
$var = $object->function_variable;
Can I do it somehow in one line?
$var = $object->function()->function_variable;
UPDATE
In general I want to call for different vars from one function in different files
$var = $object->function()->function_variable1;
$var = $object->function()->function_variable2;
$var = $object->function()->function_variable3;

Answer 1

Why doesn't function() easily return your function_variable?

Answer 2

You need to learn about the basics of oop,
If the function returns the value that you want to assign to $var, then you can do:
$var = $object->function();

Answer 3

I suppose you want to access instance variable not function variable. So it will be like:
$var = $object->function()->instance_variable;
For this to work your function should return an object with those instance variables, then only you will be able to achieve this.
For more clarity see the below example:
<?php
class Name
{
public $fname, $lname;
function __construct($fname, $lname)
{
$this->fname = $fname;
$this->lname = $lname;
}
}
class Person
{
private $name;
public function __construct($fname, $lname)
{
$this->setName($fname, $lname);
}
public function getName()
{
return $this->name;
}
private function setName($fname, $lname)
{
$this->name = new Name($fname, $lname);
}
}
$p = new Person('Raj', 'Mishra');
$name = $p->getName();
print $var = $name->fname; // $var = $object->instance_variable1;
print " ";
print $var = $p->getName()->lname; // $var = $object->function()->instance_variable2;
?>
