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 $this inside a statically called
method. I've tried these things, but they don't seem to help.
How can I rewrite my class for PHP 5 to emulate the functionality I had
in PHP 4 in an error free way?
<?php
abstract class static_my_class {
public static function format_string($string) {
}
}
class my_class {
var $elements = array();
public function __call($method, $args) {
try {
$rm = new ReflectionMethod('static_my_class', $method);
return $this->elements[] = $rm->invoke(null, $args);
} catch (ReflectionException $e) {}
}
}
static_my_class::format_string('a');
$a = new my_class;
$a->format_string('a');
?>
