                // Should copy its reference pointer to element
                // 1 of an array.

        function setScalarBVal($value) {
                $this->_b->setVal($value);
        }
                
        function getScalarVal () {
                return $this->_b->getVal();
        }

        function getArrVal () {
                $tmp_b = $this->_bObjArr[1];
                return $tmp_b->getVal();
        }
}
// Inside A object constructor, instantiates a B object, sets value of its
// $_x variable to 4, creates a copy of its reference pointer into an
// array.
$a = new A(4);
print "B obj. instantiated with x value 4.<br><br>";

print "Scalar retrieved value = " . $a->getScalarVal() . "<br>";
print "Array pointer retrieved value = " . $a->getArrVal() . "<br><br>";

$a->setScalarBVal(99);
print "\$_x set to <b>99</b> by SCALAR, retrieved by SCALAR. ";
print "Retrieved value = <b>" . $a->getScalarVal() . "</b><br><br>";

$a->setScalarBVal(99);
print "\$_x set to <b>99</b> by SCALAR, retrieved by ARRAY PTR. ";
print "Retrieved value = <b>" . $a->getArrVal() . "</b><br><br>";

$a->setBValInArr(99);
print "\$_x set to <b>99</b> by ARRAY PTR, retrieved by SCALAR. ";
print "Retrieved value = <b>" . $a->getScalarVal() . "</b><br><br>";

$a->setBValInArr(99);
print "\$_x set to <b>99</b> by ARRAY PTR, retrieved by ARRAY PTR. ";
print "Retrieved value = <b>" . $a->getArrVal() . "</b><br><br>";
?>

I configured PHP 4.0RC2 as static with configure line
./configure --with-mysql --with-apache=../apache_1.3.x --enable-track-vars --enable-track-sid

I don't think my php.ini is relevant. I'll be glad to provide it.
