Getting a value from a PHP object - php

Question

I have an object that is returns as below.
print_r($all->getInfo());
//returns the following on browser.
User Object ( [_name:User:private] => Kanye, West [_email:User:private] => kanye#hotmail.com)
I would like to read the name and email and set it to two seperate variables like below.
$email = $all->getInfo()._email;
$name= $all->getInfo()._name;
Any help would be greatly appreciated.

Answer 1

You can do somtething like this to get access to private proprites.
class sampleClass {
private $property1 = 'name';
private $prooerty2 = 'email';
public function getProperty1(){
return $this->property1;
}
public function getProperty2(){
return $this->property2;
}
public function setProperty1($name){
}
$this->property1 = $name;
}
public function setProperty2($email){
$this->property2 = $email;
}
}
To get properties:
$classy = new sampleClass();
echo $classy->getProperty1;
echo $classy->getProperty2;
To set properties:
$classy->setProperty1('name1');
$classy->setProperty2('email2');
You can also use magic methods for __get and __set, more info.

Answer 2

If you want to access the values, you can either set them to public (which may not be the best solution depending on what you're trying to do), or create the __get() magic method
class foo
{
private $value = "foo";
private $value2 = "foo2";
public function __get($name)
{
switch ($name)
{
case "value";
return $this->$name;
default:
return null;
}
}
}
class bar
{
private $value = "bar";
}
$f = new foo;
$b = new bar;
echo "Result:" . $f->value . "<br/>";
echo "Result:" . $f->value2 . "<br/>";
echo "Result:" . $b->value . "<br/>";
this yeilds
Result:foo
Result:
E_ERROR : type 1 -- Cannot access private property bar::$value -- at line 31
Of course, you can also create a function such as get_name() but then you'd have to do that for every private property you want to access.
If you want to control what is and what is not accessible from the __get() method, you can add some logic. This way you know that if you are trying to access a property, it's in the __get() method and not have to try to figure out what the method name is.
