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 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:

Hello,
Currently I'm make some utilities classes and I took the idea from java to
make some wrappers class like String, Integer and so on. This allows me to
use the type hint for basic types in php. Anyone have a clue if replacing
the all in one type in php for objects types will degrade the performance?
Also for every controller class that I'm making I'm also making exceptions
class of every error that it can generate. Same questions: It will
degrade performance to throw an exception instead of lest say a pear error
or return false?
Just for know, I'm doing this because I believe that it will eliminate
some o problems o development and will eliminate some basic validations.
Any tips appreciate
Angelo
