Hello,
as you know there is a new callback function __call($method, $params) in
php5. the __call() method of an object is called, if the method named
$method is not declared in this class.
i want this function simply call the method of another class with
SomeClass::$method(...) but i'm getting into trouble (bit heavy
programming!:) passing the arguments (stored as Array in $params) to the
SomeClass::$method([arguments]) method...
further, i think i'm getting problems with objects passed through the
__call() method?!
any suggestions?
thanks
vivi
ok, here is an example: hope you'll understand what i want...
pre
?php
class MyClass {
function __call($method, $params) {
// $params = Array(mixed var, mixed var, ...);
print(request for . $method . ()\n);
// how to get objects in this string?!
// do i have to implement switch($type) { case object: ...
} here?!
$parameterstring = \ . $params[0] . \;
eval(OtherClass:: . $method . ( . $parameterstring . ););
}
}
class OtherClass {
function OtherMethod($obj = false) {
if(is_object($obj)) {
// this method receives an object to show the
difficulties with object
passed through call...
if(method_exists($obj, printSomething)) {
$obj-printSomething();
}
}
else {
print(Error: no object passed! ' . $obj . '\n);
}
}
}
class Whatever {
function printSomething() {
print(passing object through __call() is fine\n);
}
}
$someObj = new Whatever();
// $someObj-printSomething();
$MyObj = new MyClass();
// this works perfectly
$MyObj-OtherMethod(passing a string);
// this is my problem...
$MyObj-OtherMethod($someObj);
?
/pre
please, try and help :)

Can't you just say:
OtherClass::$method($params);
here?
}
}
class OtherClass {
function OtherMethod($obj = false) {
if(is_object($obj)) {

ok, i'm sorry, but i found the solution for my own:
on the top you see some snippet of my EXAMPLE Message before.
you can implement the $parameterstring generation algorithm like this (and
its very very easy!!)
$parameterstring = ;
for($i = 0; $i count($params); $i++) {
if(!empty($parameterstring)) {
$parameterstring .= , ;
}
$parameterstring .= \$params[ . $i . ];
}
replace the line $parameterstring = \ . $params[0] . \; with this
code snippet and it works...
any way, thanks.

No, sorry that doesn't work. Interpreter is trying to acces static member
$method .. and this member does not exist.
The error message:
Fatal error: Access to undeclared static property: OtherClass::$method
in ...
Thanks for your time.
