I was not considering that, I was using $obj_string->getValue(), the
__toString method and type casting could save me some keystrokes :)
Anyway, did you abandon the development with the basic types class?

Subject: Re: [PHP] PHP 5 && OO && performance && exceptions
I myself was considering creating classes such as String, but I ran
into more basic problems before performance, for example:
class String {
protected $Value;
function __construct($Value) {
$this->Value = $Value;
}
}
$SomeString = new String("Hello World!");
Print($SomeString); // Does not print "Hello World!"
The way around this was still unsatisfactory:
class String {
protected $Value;
function __construct($Value) {
$this-> Value = $Value;
}
function __toString() {
return $this->Value;
}
}
$SomeString = new String("Hello World!");
Print($SomeString); // Prints "Hello World!"
Because this has obvious limitations, and is only a fix for strings;
this doesnt work for functions that expect integer values.
In reality, there really is no way to use PHP to rewrite a type in PHP
without using the PHP "omni-type".
However, you can use type casting as it is:
