Re: [PHP] Re: php 4 to 5
Well, I look at other people's code sice I am new to the whole language. I have only been working with it for about a month and half now. I do have prior experience with languages such as ASP (both JScript and VBscript based). I am probably not going to upgrade now since my stuff "just works". I was just wondering what would be the main advantage. - Original Message - From: "Greg Beaver" <[EMAIL PROTECTED]> To: "Travis Conway" <[EMAIL PROTECTED]> Cc: "PHP-GEMERAL" <[EMAIL PROTECTED]> Sent: Sunday, November 28, 2004 6:15 PM Subject: [PHP] Re: php 4 to 5 Travis Conway wrote: I do not know much about the history of php and do not know why there is active development on both the 4 and 5 major versions, but is there a definite reason for me to migrate from 4 to 5 on my servers?

I was just wondering what would be the main advantage. I switched to PHP over a year ago, and decided that as I was just starting I'd work with PHP5 from day one. The production releases just about kept pace with what I had to ship ( couple of sites used RC without problems for a while ). If you ARE just starting then while the volume of PHP4 code is nice, working clean with PHP5 is not a problem. All my stuff 'borrows' from PHP4 without any problem, and I am learning quickly how to switch to tidier PHP5 'rules'. I actually bought a book to help - Advanced PHP Programming by George Schlossnagle - from which I've had to rewrite some of the stuff to dump the MySQL crap ;) but gives a good grounding in getting things right. -- Lester Caine - L.S.Caine Electronic Services -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Re: PHP 4 to 5 class issues involving static methods and $this
Chris wrote:
I have a class where I need to be able to use the methods as static
methods as well as using them inside an initialized class. Here's an
example of what I need to do:
class my_class {
var $elements = array(); // holds all of my elements
function format_string($string) {
// format the string...
return $this->elements[] = $string;
}
function show_all() {
return implode("\n", $this->elements);
}
}
This worked fine in PHP 4. It silently ignored the $this->elements[]
assignment in statically called methods and just returned my formatted
string without any fuss. However, in PHP 5, I understand that I'm now
required to declare the method format_string as public static if I want
to just call my_class::format_string(), and if I want to use $elements
inside a static method, it also requires being declared as static. I
also understand that I can't use $this inside a statically called
method. I've tried these things, but they don't seem to help.
How can I rewrite my class for PHP 5 to emulate the functionality I had
in PHP 4 in an error free way?
elements[] = $rm->invoke(null, $args);
} catch (ReflectionException $e) {}
}
}
static_my_class::format_string('a');
$a = new my_class;
$a->format_string('a');
?>
