class TestClass{

function method_a(){
// do something
}

function method_b(){
// do something
}

function testcall(){
$functionname="method_a";

if(function_exists($function)){
echo "found<br />";
}else{
echo "not found<br />";
}
}

}

when I new an object it always echo not found??

How can I reference the class function??

anybody can help me ??

I think it should be something missing such as "$this->"

is it possible to do this ???

thx all!!

You're almost there, and thinking along the right lines...

Instead of
>>if(function_exists($function)){

(which should incidentaly have read if(function_exists($functionname)){)

you want if (method_exists($this,$functionname)) {

Classes have methods, even though php uses the keyword "function" to define them (as do several other laguages actually!) so because it's a class method rather than a normal function, you use method_exists() rather than funtion_exists()
