Consider the following: function test() {

} while( $bob = test()) {

    echo $bob . '<br>';

} while(false !== ($bob = test())) {

     echo $bob . '<br>';

}

You would expect the while loop to go on forever just looking at the above code. However, what's happening is that when the empty string is getting returned due to $i being > 10, the while loop is resolving FALSE when $bob is set to the value of the empty string. Is there any way that I can force this not to happen? That the while loop resolves as FALSE only when the function actually returns a (boolean) FALSE value? thnx, Chris
