[PHP]About the magic function __call
Hi there!
I'm working with the following code:
?php
abstract class Foo{
protected $a;
protected $b;
protected $c;
function __construct($arg){
$this-a = $arg;
}
function __call($function, $args){
$this-b = $function;
$this-c = $args;
$this-doWhatever();
}
private doWhatever(){
}
}
class Boo extends Foo{
protected $e;
public function __construct(){
parent::__construct('Blah');
}
public function drive(){
$e = 'testing';
parent::drive($e);
}
}
$br = new Boo();
$br-drive();
But I get a Fatal error: Call to undefined method Foo::drive()
The magic fuction __call don't catch the drive(). Why not?
I need another idea for this problem and avoid edit the abstract class.
Sorry about the english.
Thanks for any help

looks like __call() might not work through a subclass if defined in the
parent; i might poke around in the .phpt tests that come w/ the php source
to ensure this is the correct behavior.
in the meantime you can get away w/ some variant this ugliness,
class B extends A {
function __call($method, $args) {
return parent::__call($method, $args);
}
}

this *should* work,
here is a test, tests/classes/__call_005.phpt, you can take the part beneath
the --FILE-- section and see if it blows up on your system or not.
right now, im getting errors on a php5.2.5 system, and its working as
expected on a php5.2.6 system.
--TEST--
When __call() is invoked via ::, ensure private implementation of __call()
in superclass is accessed without error.
--FILE--
?php
class A {
private function __call($strMethod, $arrArgs) {
echo In . __METHOD__ . ($strMethod, array( .
implode(',',$arrArgs) . ))\n;
var_dump($this);
}
}
class B extends A {
function test() {
A::test1(1,'a');
B::test2(1,'a');
self::test3(1,'a');
parent::test4(1,'a');
}
}
$b = new B();
$b-test();
?
--EXPECTF--
In A::__call(test1, array(1,a))
object(B)#1 (0) {
}
In A::__call(test2, array(1,a))
object(B)#1 (0) {
}
In A::__call(test3, array(1,a))
object(B)#1 (0) {
}
In A::__call(test4, array(1,a))
object(B)#1 (0) {
}
also, i found in the code you posted, you are missing a 'function' in front
of doWhatever (cause a parse error, which is why i mention it); w/ the
following modification to your code, its running fine on a php 5.2.6 system,
and choking on 5.2.5;
function __call($function, $args){
var_dump($function);
var_dump($args);
$this-doWhatever();
}
private function doWhatever() {
}

Re: [PHP]About the magic function __call
My information was incomplete: I'm running php 5.1.2 (a requirement from the
customer).
I found this http://bugs.php.net/bug.php?id=42937
I coded this without testing, using only the idea. Thanks!
Thanks for the help Nathan!
