 Excercises for OOP beginners?
Ok, like a lot of people, i'm a beginner with OOP in php. I'm asking the very experienced people here, what sort of excercises or scripts to try and do first using OOP to better my knowledge?

I would personally start of by making an object and writing members to change it's properties and then get used to calling those members from within the class and from outside the class.
IE
PHP Code:
class newClass
{
public $property;
function __construct($property)
{
$this -> property = $property;
}
public function changeProperty($property)
{
$this -> property = $property;
}
public function nullProperty()
{
$this -> property = $this -> changeProperty(NULL); #In this line we called the function we made before to change the property and supplied the null value for it.
}
}
$Obj = new newClass("Object 1");
echo "The current property is: ".$Obj -> property."<br />"; // Outputs "The current property is: Object 1"
$Obj -> changeProperty("Object 1 V2");
echo "The current property is: ".$Obj -> property; // Outputs "The current property is: Object 1 V2"
$Obj -> nullProperty();
echo "The currenty proprety is: ".$Obj -> property; // Outputs "The current property is: "
I hope that helped. The script should work - but knowing me and my lax syntax and error checking .. it might not

You should note that his code that he wrote above is for PHP5, PHP4 lacks in OOP functionality.

Stay away from PHP4, it is as a whole depreciated at this point.
For scripts, make any semi-large script and implement OOP on it, try a user system.

No problem 
And yes, Creative Logic is right. That script is\was for PHP 5. Some of the keywords used aren't in PHP 4.

For absolute beginners in OOP i would recommed them to look at the PHP4 tutorials as they give a basic and abit easier understanding of learning OOP in PHP and then move on to the differences in PHP5.
But in general i can only agree with staying away from PHP4 in general, but for learning basic OOP and testing it does the job

I learned OOP with PHP5 and never had a problem.
Thanks to Village Idiot.

PHP4 and 5 are almost identical till you get to some advanced concepts, although some basic concepts have better functionality. Why start a beginner on bad standards?
