Re: [PHP] Dynamic Function with return?

[Michal Migurski]

 This code works.  It calls the function and receives the appropriate
 return value.
  But, is there a better way of doing this? It seems a bit round-a-bout.

Two options, details in the manual: call_user_func() or create_function().

[PHP] Dynamic Function with return?

[bskolb]

Sample Code:
 
//
?PHP // version 4.3.6
function testFunction($foo) {
return $foo==TEST;
}
 
function wrapper($foofunc, $foovar) {
return eval(return $foofunc($foovar););
}
 
echo wrapper(testFunction, TEST);
?
//
 
This code works.  It calls the function and 
receives the appropriate return value.  
 
But, is there a better way of doing this?
It seems a bit round-a-bout.
 
 
Thanks!

[PHP] SOLVED RE: [PHP] Dynamic Function with return?

[bskolb]

Thanks for the quick reply, I wasn't aware that passing a variable for the
object would work.   

New code:

class testClass {
function testFunction($foo) {
return $foo==TEST;
}
}

$testObj = new testClass;   
$testFunc = testFunction;

echo $testObj-$testFunc(TEST);

Did you already try this?  
function wrapper($foofunc, $foovar){
 return $foofunc($foovar);
}

Maybe I'm missing something, but I don't see the need for the eval since PHP supports 
variable function names.
