Re: Dissappearing instance variables; Bug or Feature?

In PHP4 "$this->one = $one;" assigns a *copy* of $one to $this->one. You need to use "$this->one =& $one;" The code will work as expected in PHP5 (and zend.ze1_compatibility_mode set to off). Ryan Briones wrote:

This is a scaled down example of something I'm doing in some code. The results are very funky. I guess I could understand this happening if $two was out of scope when print_r($this) was called in One()...actually no I couldn't. <?php Class One {

    function One() {
        $this->test = array();
        $two = new Two( $this );
        print_r( $this );
    }
        function set( $index, $value ) {
        $this->test[$index] = $value;
    }

} Class Two {

    var $one = null;
    function Two( &$one ) {
        $this->one = $one;
        $this->one->set( 'foo', 1 );
        print_r($this);
    }

} $obj = new One; ?> OUTPUT: two Object (

    [one] => one Object
        (
            [test] => Array
                (
                    [foo] => 1
                )

        )

) one Object (

    [test] => Array
        (
        )

) This only happens if you assign the reference passed to the second class as an instance variable. If you call the reference directly, the variable persists. ie: <?php Class One {

    function One() {
        $this->test = array();
        $two = new Two( $this );
        print_r( $this );
    }
        function set( $index, $value ) {
        $this->test[$index] = $value;
    }

} Class Two {

    var $one = null;
    function Two( &$one ) {
        $one->set( 'foo', 1 );
    }

} $obj = new One; ?> OUTPUT: one Object (

    [test] => Array
        (
            [foo] => 1
        )

) Any Ideas? Ryan Briones
