Recurse an array with an object/s

[Aggelos]

Hello,
I am using php4
And I have a class product
I create an array of productObjects that has 2 dimensions.
Generraly I am sorting my objects inside arrays and I need to some how
recurse those arrays to get to the objects.

To do that I am using the following method recurseArray()

function recurseArray($a rray) {
if(is_array($ar ray)) {
foreach($array as $arrayValue) {
recurseArray($a rrayValue);
}
}
elseif(is_objec t($array)) {
$object = $array;
return $object;
}
}

the problem with that is that when i try to do
$_product = recurseArray($p roductArray)
print_r($_produ ct);

it won't pring anything. But if i do the pring inside the method like
that
....
elseif(is_objec t($array)) {
$object = $array;
print_r($object )
return $object;
}
....
it will print my object.

Do you know why is this happening ?
It makes me crazy !!!
Thanks, Angelos.

Hi,

Please try: return recurseArray($a rrayValue);

Should do the trick.

This won't do anything, you returned objects are cast in the void....

How would you like your objects returned by the function? In case of a
flat array (which I suspect):
function objects_from_ar ray($var){
$return = array();
if(is_object($v ar)){
$return[] = $var;
}
if(is_array($va r)){
$return = array_merge($re turn,objects_fr om_array($var)) ;
}
return $return;
}

That would just loop forever... won't it ?

[Aggelos]

function objects_from_ar ray($var){

$return = array();
if(is_object($v ar)){
$return[] = $var;
}
if(is_array($va r)){
$return = array_merge($re turn,objects_fr om_array($var)) ;
}
return $return;}

That function will also enter an endless loop like petesprc
We need to loop inside the array to get the next dimension... don't
we ? so when you do arraymerge the $var should be the second dimension
of the array in the first call of the function.

Isn't that right ?
So I suppose I need to have a foreach loop

my array is like that
$productArray[$productTypeId][$productId][$published] = new
objectProduct() ;

so for that i would do 3 nested foreach loops ...
But I want to do that using a function to get to the objectProduct.

Oops,
if(is_array($va r){
foreach($var as $item){
$return = array_merge($re turn, objects_from_ar ray($item));
}
}

> }
return $return;}

No, it won't like this :P. It will loop through an array and if it's done,
it will return all objects found. Unless you're doing something very
strange like putting in a reference to a parent array in a sub array.

We need to loop inside the array to get the next dimension... don't
we ? so when you do arraymerge the $var should be the second dimension
of the array in the first call of the function.

my array is like that
$productArray[$productTypeId][$productId][$published] = new
objectProduct() ;

so for that i would do 3 nested foreach loops ...

Or just a recursive function.

function objects_from_ar ray($var){
$return = array();
if(is_object($v ar)){
$return = $var;
}
if(is_array($va r)){
foreach($var as $item){
$return = array_merge($re turn, objects_from_ar ray($item));

}
}
return $return;
}

Ok that will work now but it is not what I want because at the end my
object gets converted into an assiciative array.
So my product->title now would become product[;title']

Do you know why my version isn't working ? you said something about
void... but i didn't understood that...

Not in my code, I assume in something you want to do afterwards? I told
you I did not know in which format you want the return.

Euh? That's something entirely different. Please explain your exact
intentions from start to finish, would make it a lot easier to give you an
answer you can actually use :-)

This part:
function recurseArray($a rray) {
if(is_array($ar ray)) {
foreach($array as $arrayValue) {
recurseArray($a rrayValue);
-----------------------^^

If the $array you feed it is an object, the same object is immediately
returned. So far so good. If it is an array, you perform the function on
each item of the array. This may or may not return an object. However,
there's nothing 'to the left' of this recurseArray($a rrayValue), which
means that whatever it returns, it is not assigned to anything, so
whatever it returns is lost. If you feed it an array, the function is
performed on every item, but isn't 'saved'. The only 'return' there is for
when it's an object, so if it's not an object your function will return
nothing/null/nada.

Not unless you have a loop in your array itself.

Your problem is you're only returning something if the last item in the
first level of your array is an object. Otherwise you're not returning
anything - so print_r has nothing to print.

But one question - you say you have a two dimensional array. But this
is only a single dimensional array. It just happens that an array
element might itself be an array. That's not two dimensions.

Why not try posting some sample data and what you're trying to get out
of it? Then maybe we could help you a little better.
