Does class function exist

I'm trying to write a simple function in a class which will display debug information if the function doesn't exist. However I don't know how to specify $this->myfunction name. What I've been working on is:-

    class pageHandler {
        function showMain($arrayData) {
        function callFunction($functionName, $arrayData) {
            if (function_exists($functionName)) {
                call_user_func(array($this, $functionName),$arrayData);
            } else {
                echo "Function $functionName not yet declared<br/>" . print_r($arrayData,true);
    $newTest = new pageHandler();
    $newTest->callFunction("showMain",array('para1'=>'val1', 'para2'=>'val2'));

Open in new window

Any ideas how I should be testing function_exists for a class?

Thank you
