Question

Even that my system is still functioning properly my error-log is suddenly overflowding with errors like these:

2012-07-20T02:53:25+00:00 WARN (4): [2048] Declaration of User_Model_User::getParent() should be compatible with Core_Model_Item_Abstract::getParent($recurseType = NULL) ([…]/application/modules/User/Model/User.php) [20]

All Models using the Core_Model_Item_Abstract will produce the exact same error.

The strange thing is that the error only show on the production server (running PHP 5.4.3) and not on the development setup (running PHP 5.2.11).

From the error it is clear that the Core_Model_Item_Abstract do not seem to get the expected parameters, but no changes have been make to the Core_Model_Item_Abstract and if it was the case it would properly show in both production and development.

[EDIT]

The parent class in Core_Model_Item_Abstract looks like this. For me it seems like the code is already taking into account that $recurseType is not set:

public function getParent($recurseType = null) {
    if( empty($recurseType) ) $recurseType = null; // Parent and owner are same
    if( !empty($this->_parent_is_owner) ) { 
        return $this->getOwner($recurseType); 
    }
}

Anybody have any thoughts on this?

Answer 1

Change

class User_Model_User {
    function getParent() {
    ...

to

class User_Model_User {
    function getParent($recurseType = NULL) {
    ...

and the problem should go away. This change will not break anything, but will only quiet your logs.

Or you could do this:

abstract class Core_Model_Item_Abstract 
{
  public function getParent(/*$recurseType = NULL*/)
  {
      $recurseType = NULL; # forcing to null as no one is passing this parameter
      ...
  }
}
