get property in PHP

Hi guys,

I am relatively new to PHP, have more experience with other OOP language. Can someone tell me how are the get, set properties handled in PHP?Tried to get some ideas, but not sure about the __get() __set() functions.
Cheers

see php manual for details or do a google search for it

 

Haha, well that isnt very helpful advice

The __set and __get are used for function overloading. They're basically called if you're trying to access or read variables of an object.

So for example, if you do something like

echo $object->var;

It will return run the function __get and do whatever you have defined


Similarly, if you try

$object->var = 'test';

The __set function will be run.

Hope this helps

 

well after some google-ing I had mixed feelings, but yeah tonybogs you gave an interesting answer. So I assume the following is right:
class TestClass
{
private $_var;
public function __get()
{
return ($_var);
}
}

public function __construct($var)
{
$_var = $var;
}

$test = new TestClass('this is a test');
//and the code below will call the __get function and print the text in the constructor?????
echo $test->var;


I have used another OOP language (C#), and there is a slightly different approach of properties, but I assume the code above is more likely to be OK.Please let me know your opinion.
Thanks

Ben
