Getters And Setters In Php	View Content

I'm having issues with getter and setter functions in PHP. Following is how I have written my PHP classes.
--------------------------------------------------------------------------------------------------------------------
File1.php
--------------------------------------------------------------------------------------------------------------------
Code: [Select]
<?php
class TestClass1 {
    private $var;
     public function get_varvalue() {
        return $this->var;
    }

    public function set_varvalue($TestVar) {
        $this->var = $TestVar;
    }
}
?>

--------------------------------------------------------------------------------------------------------------------
File2.php
--------------------------------------------------------------------------------------------------------------------
Code: [Select]
<?php
$obj = new TestClass1();
$obj->set_varvalue("someText");
?>

--------------------------------------------------------------------------------------------------------------------
File3.php
--------------------------------------------------------------------------------------------------------------------
Code: [Select]
<?php
class TestClass2 {
   $obj2 = new TestClass1();
   echo $obj2->get_varvalue();
}
?>
File1, File2 and File 3 are separate PHP files. File2 uses the TestClass1 object to set the value to variable 'var' but when I try to get the value print the value in File3.php by creating an object for the same class and calling the get_varvalue() function, I'm getting a blank output.

Please help me to solve this issue.

Thank you.

I know that magic __get and __set are invoked automatically when an object is instantiated, but what about stuff like getName() and setName()

Code: [Select]
class NameClass {
private $_name;
public function getName() {
return $this->_name;
}
public function setName($value) {
$this->_name = $value;
}
}

$someName = new NameClass();
$someName->setName('Bob');
echo $someName->getName();
1. Could the setName() and getName() just as easily be named something generic like:

hotName()
coldName()

Code: [Select]
class NameClass {
private $_name;
public function hotName() {
return $this->_name;
}
public function coldName($value) {
$this->_name = $value;
}
}

$someName = new NameClass();
$someName->coldName('Bob');
echo $someName->hotName();
2. Also, the setName() and getName() methods must be called manually, right? Unless they are manually called, they just sit there, do nothing, am I correct?

Thanks
