I still can not reproduce this with the class extending mysqli. Please
try the snapshot. (And next time, DO NOT use the "Add comment" tab when

Sorry, expected and actual result are as this:

Expected result:
----------------
   Publish_date: 45678
   publish IS NOT EMPTY!

Actual result:
---------------
   Publish_date: 45678
   publish IS EMPTY!

Ok, I found the root of problems. Seems it fails when the class extends
mysqli class (?¿). See this:

Reproduce code:
---------------
FooClass.php
class FooClass extends mysqli
{
   var $publish_date;
   function __construct()
   {
   }

   function foo( $var )
   {
      $this->publish_date = $var;
      echo "Publish_date:".$this->publish_date."<br>";
      if( empty( $this->publish_date ) )
         echo "publish IS EMPTY!<br>";
      else
         echo "publish IS NOT EMPTY!<br>";
   }
}



Index.php

include ("FooClass.php");
$obj = new FooClass();
$obj->foo( '45678' );



Expected result:
----------------
   Publish_date: 45678
   publish IS NOT EMPTY!

Actual result:
---------------
   Publish_date: 45678
   publish IS NOT EMPTY!


I expect this time you can reproduce it.

Seems like my example code does not reproduce the error. I'll try to
reduce my failing code to write here.

Description:
------------
empty( $this->variable ) returns always true.


Reproduce code:
---------------
class FooClass
{
    var $publish;
    function foo()
    {
       $this->publish = '123456';
       if( empty( $this->publish ) )
           echo "publish is empty.";
       else
           echo "publish is NOT empty.";
    }
}

Expected result:
----------------
"publish is NOT empty."

Actual result:
--------------
"publish is empty."
