I'm getting this error in php. I'm trying to use substr in a class.
Here is my code:

```
<?php
Class Test{
    public $name = "for testing only";
    public $part = substr($this->name, 5, 2);

    public function show() {
        echo $this->part;
        echo $this->name."\n";
    }
    public function change($data) {
        $this->name = $data;
    }
}

$myTest = new Test();
$myTest->show();
$myTest->change("something else");
$myTest->show();
?>

```

Aptana highlights the ( and the first , on line 4 and tells me "syntax error".

Netbeans highlights the whole line 4 and tells me 

> 
> unexpected: ( expected =>,::,',`,OR,XOR and lots more.
> 
> 
> 

When I run the code as a PHP script using Aptana Run menu the error message is: 

> 
> Parse error: syntax error, unexpected '(', expecting ',' or ';' in
>  C:\path\to\file\test.php on line 4
> 
> 
> 

When I change `$this->name` to `$name` the Aptana only highlights the `(`
When I use this code from Interactive Mode in Windows it seems to work:

```
Interactive mode enabled

<?php $name = "for testing only";
$part = substr($name, 5, 2); 
echo $name; echo $part; 
?> 
^Z
for testing onlyes

```

Does anyone know what I am doing wrong? Is `substr()` allowed inside a class?
