Hello,


In the following example source:

<?php

class A
{
	var $property = 'string value';

	function methodA()
	{
		echo "$this->property\n";
	}
}

class B
{
	var $objArray   = array();
	var $currentObj = 0;

	function B()
	{
		$this->objArray[$this->currentObj] = new A;
	}

	function methodB($index = 0)
	{
		return $this->objArray[$index];
	}
}

$b = new B;

/*
 * This works:
 */
$b->objArray[$b->currentObj]->methodA();

/*
 * But this don't:
 */
// $b->methodB()->methodA();

?>

Is it possible to get this work? It is something like collections in JScript of Internet Explorer, for example:

<HTML>
<SCRIPT LANGUAGE="JScript">
function numberCells() {
    var count=0;
    for (i=0; i < document.all.mytable.rows.length; i++) {
        for (j=0; j < document.all.mytable.rows(i).cells.length; j++) {

            // Looks like rows() is method of mytable and
            // cells() is method of object returned by rows()
            document.all.mytable.rows(i).cells(j).innerText = count;
            //                   ~~~~~~~ ~~~~~~~~

            count++;
        }
    }
}
</SCRIPT>
<BODY onload="numberCells()">
<TABLE id=mytable border=1>
<TR><TH>&nbsp;</TH><TH>&nbsp;</TH><TH>&nbsp;</TH><TH>&nbsp;</TH></TR>
<TR><TD>&nbsp;</TD><TD>&nbsp;</TD><TD>&nbsp;</TD><TD>&nbsp;</TD></TR>
<TR><TD>&nbsp;</TD><TD>&nbsp;</TD><TD>&nbsp;</TD><TD>&nbsp;</TD></TR>
</TABLE>
</BODY>
</HTML> 

The following example works in PHP3, but not in PHP4:

<?php

class A
{
	var $var = 'some value';
}

class B
{
	var $date = date('Y.m.d');
	var $a = new A;
}

?>

Is it possible to get it work in PHP4? Maybe, in the future versions of PHP4?

If it's possible let me know about this.

P.s. Sorry for my English.

For both your requests are already feature requests filed.
So I'm marking this one as duplicate. However, I was to lazy to look up the bug id's, and that's why I didn't add them here.

IIRC, this is possible in ZE2. Closed.
