$result = $className::$me thodName(); - possible?

[Joshua Beall]

Hi All,

I have been trying to dynamically call a static member function, as follows:

$className = 'MyClass';
$methodName = 'MyMethod'
$result = $className::$me thodName();

However, I get a parse error when I do this:

Parse error: parse error, unexpected T_PAAMAYIM_NEKU DOTAYIM in
/home/HE/web_develop/ghea/www/cgi-bin/lib/EventRegistrati onBridgerClasse s.inc
on line 28

Line 28 is indeed the line in which $result = $className::$me thodName();
appears.

Is there any way to do what I am trying to do? I have had success
dynamically calling methods on known classes. E.g.,

$methodName = 'MyMethod';
$result = MyClass::$metho dName();

This works fine. What if I want to have the class name dynamically defined
as well? Is there any way to do that?

Thanks for any pointers!

call_user_func( ) should help.

In your code is the semicolon(;) missing or is that a typo?
$className = 'MyClass';
$methodName = 'MyMethod'; <---- semicolon
$result = $className::$me thodName();

Oops, typo - sorry about that.

I simplified my code for the sake of example, and I missed that semicolon.

call_user_func( array($classNam e,$methodName), $parameter); did the trick.
Thanks for the pointer, Michael.

$className = 'MyClass';

$result = call_user_func( array($classNam e, $methodName));

There's a workaround, at least:

$result = call_user_func( array($classNam e,$methodName), <any parameters
here>);

The problem is that $className::$me thodName() results in an error simply
because $className is a string, not an object.
$$className won't work because $MyClass is an undefined variable and not
an object.

I think eval() might solve that.
Try something like

eval($className .'::'.$methodNa me.'();');

This *should* translate the string into

MyClass::MyMeth od();

and execute it.

I'm sure that eval() will help you out but I haven't tested this.
