php call_user_func_array（）警告

Question

I am using following code in my program.

class A {
function __call($fname,$arguments)
{
    $methods = array('get', 'set');
    foreach ($methods as $method) {
        if(strstr($fname,$method))
        {
            $fname = str_replace($method, "", $fname);
            $function = $method."method";
            if($method == "set")
            {
                call_user_func_array("setmethod", array($fname,$arguments[0])); 
            }
            if($method == "get")
            {
                call_user_func_array("getmethod", $fname);
            }
            break;
        }
    }
}

function setmethod ($key,$value)
{
    $this->$key = $value;
}

function getmethod($key)
{
    return $this->$key;
}
}

and I am getting warrning like this

"Warning: call_user_func_array() expects parameter 1 to be a valid callback, function 'setmethod' not found or invalid function name"

and the program get stopped nothing is displayed further.

Answer 1

You are trying to call the global function, while what you need to call the the object member method.

Use an array to present the callback:

call_user_func_array(array($this, "setmethod"), array($fname,$arguments[0])); 

Same as:

call_user_func_array(array($this, "getmethod"), $fname);
