Description:
I have a number of feature requests:
1) Could it be possible to immediately access an array that was
returned from a function, just like its possible to access object
functions immediately? This way its easy to safely access arrays that
are privately stored inside an object (so that another person can not
(accidentally) change information inside that array.
i.e. $temp=$object->return_object($parameter)->data($key);
for an array (that is privately kept inside an object):
$temp=$object->return_array($parameter)[$key];
where $object->return_array would be like:
function return_array(){
return $copied_array=$private_array;
}
This same (feature request) has been asked in report 25898, but the
given "possible solution" did not seem to match my question.
2) Could it be possible for functions that accept parameters by
reference, and return values by reference, to also accept static
value's like strings or booleans?
This would be very nice in situations where I would have to accept a
large string PLUS a small piece of text like "hey", and it would be
very usefull too in situations where I would have to return either an
array or FALSE.
like this:
$data="hey";
test(TRUE, $data."");
function test($param1, &$param2){
$data=array($param2, "bye");
If($param1)
{
return $data;
}
else
{
return FALSE;
}
}
The above script will fail with beta 3 on both the parameters (since a
static string was part of $param2) and the return value (Becouse FALSE
is also not a variable)
This is a functionality I have used alot in other programming
languages, without problems. Sending strings by reference will (in my
opinion) make it possible to optimize your scripts a little more.

#25957 [NoF->Opn]: bad one? mixingup of array / $this-> in memory

Sorry for late update.
I think I have found the cause of the problem, if you have 2 objects, 1
is parent, other is child, en in both you have defined the __destruct()
function, and you call the childs __destruct() function, then stuff
gets really mixed up...
for the rest I have had _no_ problem yet, GREAT JOB PHP5!! :)

Provide a complete (preferrably short as possible) example script.

Description:
In a class I send an array $test as a parameter to a protected
function. Then, if I try to access that array in any way in that
function, suddenly the $this object contains the data of that array
$test (!)
Reproduce code:
---
Sorry, cant make a short-and-clear reproducing code, but here I have a
small code sample that actually caused the problem: (note that
$this->params["source"] _IS_ an array)
protected function get_body($css){
echo "B0 (";
print_r($this);
echo ")";
flush();
$retval="";
while(list($key, $cell_data)=each($this->params["source"])){
echo "B1 (";
print_r($this);
echo ")";
flush();
Expected result:
I will try to get a .zip together with the classes that seem to cause
this problem.
Actual result:
--
B0 (table_key_value_a Object ( [params:protected] => Array ( [source]
=> Array ( [crc] => mBjsS50UkhAnxjWp [sid] => 75 [test_site] =>
75,mBjsS50UkhAnxjWp ) [col headers] => Array ( [0] => Key [1] => Value
) [table header] => HTTP VARIABLES [css prefix] => debug [table header
extra] => align='center' ) ) )

#25898 [NEW]: array returning mechanism from objects?
From: sven at leon dot uia dot mx
Operating system: All (redhat 90)
PHP version: 5.0.0b1 (beta1)
PHP Bug Type: Class/Object related
Bug description: array returning mechanism from objects?
Description:
Im not sure if it is a bug or not.
with an object inside an object, this is possible:
echo $test->testobject()->color;
with and array inside an object, this is NOT possible:
echo $test->testarray()["color"];
In other words, when an object returns an array, I can not directly access
it.
This will work:
$temparray=$test->testarray();
echo $temparray["color"];
Reproduce code:
---
color="red";
}
}
class c_test{
private $testobject; private $testarray=array("color" => "red");
function testobject(){
$testobject=new c_testobject;
return $testobject;
}
function testarray(){
return $testarray;
}
}
$test=new c_test();
echo $test->testobject()->color;
echo $test->testarray()["color"];
?>
Expected result:
redred
Actual result:
--
Parse error: parse error, expecting `','' or `';'' in
/var/www/html/php-easy/test.php on line 19
