calling method of object of object with call_user_func

问题

consider this simple scenario:

$this->method($arg1, $arg2);

Solution:

call_user_func_array(array($this,'method'), array($arg1, $arg2));

consider this scenario:

$this->object->method($arg1, $arg2);

Should this solution work?

call_user_func_array(array($this->object,'method'), array($arg1, $arg2));

Or should this work?

    call_user_func_array(array($this, 'object','method'), array($arg1, $arg2));

Edit: Will try/catch works for SOAP exception, triger while using call_user_func?

  try {
    $soap_res = call_user_func_array(array($this->service,'getBanana'), array(0, 10));
} catch (SoapFault $fault) {
    die($fault->faultstring)
} 

回答1:

This should work:

call_user_func_array(array($this->object,'method'), array($arg1, $arg2));

The first argument is a callback type, containing an object reference and a method name.

回答2:

Here's a hackish variant, might be useful to someone:

$method_name_as_string = 'method_name';
$this->$method_name_as_string($arg1, $arg2);

This uses the PHP variable-variables. Ugly as hell, but not particularly uglier than the others...
